Description

{POWER MANAGEMENT DEVICE ASSOCIATED WITH SOLAR POWER AND CONTROLLING METHOD THEREOF}

Various embodiments of the present disclosure relate to a power management device associated with solar power generation and a control method thereof.

In the past, monitoring of PV systems was limited. Although PV is recognized as an important form of renewable energy, these systems can cause potential problems and inefficiencies if not properly monitored. Therefore, monitoring of PV systems is a very important factor.

Monitoring systems of the past have limited data collection and analysis capabilities. This makes it difficult for operators to track the performance and operating status of power generation systems in real time or to predict potential problems in advance. These limitations have resulted in problems such as reduced power generation, equipment failures or malfunctions, and additional maintenance and costs to resolve them.

Additionally, the absence of a remote monitoring and management system made it difficult for operators to monitor and manage the status of the power generation system in real time. This limited operational efficiency and troubleshooting capabilities, and could have created potential security threats that could affect the safety and reliability of the system.

There is a need for an effective system and method for monitoring solar power generation systems. Such a system should provide the ability to track and monitor the performance of the power generation system in real time, allowing early detection of potential problems and taking preventive measures. It should also have the ability to remotely monitor and manage the system, allowing operators to operate the system efficiently anytime and anywhere.

On the other hand, in addition to simple monitoring of solar power generation, immediate response is required when a system problem occurs. Even if the solar power generation decreases due to a system problem, if the manager is not aware of it, the response may be delayed. If the response is delayed, economic loss may occur due to the decrease in power generation during that time. In addition, if the solar power generation system is installed remotely, it may take time for the user to visit directly to solve the problem, and thus economic loss may occur due to the decrease in power generation.

The present disclosure has been made to solve the above-described problems, and can provide a power management device related to solar power generation capable of performing an immediate reset when a problem occurs, and an operating method thereof.

In one embodiment, a power management device may include an input power interface for receiving power from a wall power source, a plurality of output power interfaces configured to be electrically connected to each of a plurality of devices for processing and/or monitoring power provided from a solar panel, a plurality of switches, and a controller. Here, each of the plurality of switches may be configured to selectively electrically connect each of the input power interface and the plurality of output power interfaces. The controller may be configured to identify information associated with power generation by the solar panel and/or an error associated with at least some of the plurality of devices, and based on the identification of the error, control the state of at least some of the plurality of switches corresponding to at least some of the plurality of devices to an OFF state, control the state of at least some of the plurality of switches to an OFF state, control the state of at least some of the plurality of switches to an ON state after a specified period of time has elapsed, and then determine whether an error associated with at least some of the plurality of devices and/or the information associated with power generation by the solar panel has occurred.

A method of controlling a power management device may be provided, comprising: an input power interface for receiving power from a wall power source; a plurality of output power interfaces configured to be electrically connected to respective devices for processing and/or monitoring power provided from a solar panel; and a plurality of switches. Here, each of the plurality of switches may be configured to selectively electrically connect the input power interface and each of the plurality of output power interfaces. The control method may include an operation of checking information associated with power generation by the solar panel and/or an error associated with at least some of the plurality of devices, an operation of controlling a state of at least some of the plurality of switches corresponding to at least some of the plurality of devices to an off state based on the checking of the error, an operation of controlling the state of at least some of the plurality of switches to an off state and, after a specified period of time has elapsed, controlling the state of at least some of the plurality of switches to an on state, and an operation of checking, after controlling the state of at least some of the plurality of switches to an on state, whether an error has occurred associated with information associated with power generation by the solar panel and/or at least some of the plurality of devices.

According to the present disclosure, a power management device associated with solar power generation capable of performing an immediate reset when a problem occurs and a control method thereof can be provided.

Figure 1 is a drawing for explaining a solar power generation system according to one embodiment.

According to one embodiment, the solar power generation system may include a plurality of monitoring devices (10) associated with the solar power generation. Each monitoring device (10) may include a router (11), a shared device (12), a communication device (13), a connection panel (14), an inverter (15), and/or a distribution panel (16).

According to one embodiment, the router (11) can provide internet connectivity and transmit data of the solar power generation system to the outside. The router (11) can remotely access and monitor the system and securely store related data. The router (11) (or another router (4)) can, for example, provide information monitored within the system to an external client user (1) (or a client application). For example, at least one external UPS (2), a switching hub (3), and/or another router (4) can further operate (or be connected to, or utilize) for communication between the client user (1) (or the client application) and the router (11), but is not limited thereto.

According to one embodiment, the UPS (2) can supply stable power to the connected device even in an abnormal power situation, thereby preventing data loss and device damage. The main functions of the UPS (2) are to protect the device from intermittent power supply interruption or power punching, and to maintain stable operation in case of temporary power problems.

According to one embodiment, the switching hub (3) can perform a role related to data transmission in a communication network. The switching hub (3) can manage data flow between multiple devices and control packet switching and data transmission. This enables rapid and stable data communication between devices within the network, and the performance and stability of the network can be maintained.

Therefore, the UPS (2), switching hub (3), and other routers (4) can perform their respective roles in the communication system to ensure stable power supply and data communication. These devices can be interconnected within the communication system to provide a smooth data flow and stable communication environment. In particular, a remote client user (1) (or client application) can receive information related to solar power generation.

According to one embodiment, the router (12) can facilitate communication between the router (11) and the communication device (13) and manage data flow. The router (12) can manage network connections and enable sharing and transmission of data between various devices.

According to one embodiment, the communication device (13) may be implemented as, for example, a serial-to-Ethernet converter. For example, the communication device (13) may transmit/receive data with the router (11) and/or the shared device (12) via TCP/IP communication, but there is no limitation on the communication method. The communication device (13) may be assigned, for example, an IP address. The communication device (13) may transmit/receive data with the connection panel (14), the inverter (15), and/or the power distribution (15) based on RS-485, but there is no limitation on the communication method. Accordingly, the communication device (13) may receive data from the connection panel (14), the inverter (15), and/or the power distribution (15) and/or data sensed with respect to the connection panel (14), the inverter (15), and/or the power distribution (15) based on RS-485. The communication device (13) can generate a packet based on the received data. The communication device (13) can transmit the generated packet to the router (11) and/or the sharing device (12) via TCP/IP communication. Accordingly, a remote client user (1) (or client application) can receive data from the connection panel (14), the inverter (15), and/or the distribution panel (15) and/or data sensed for the connection panel (14), the inverter (15), and/or the distribution panel (15), and display a screen using the data.

According to one embodiment, the connection board (14) can perform a connection between the solar panel and the inverter (15). The connection board (14) can transfer the generated solar energy to the inverter (15) and perform power conversion and control.

According to one embodiment, the inverter (15) can convert direct current (DC) power generated from the solar power generation system into alternating current (AC) power. The inverter (15) can control and adjust power quality before supplying the generated power to the electric grid or connected electric system.

The distribution system (16) can distribute power to the electric grid connected to the solar power generation system. The distribution system (16) can guide the generated power to an appropriate electric circuit and maintain a stable connection with the grid.

According to the above, a remote client user (1) (or client application) can receive data from the connection panel (14), the inverter (15), and/or the power distribution unit (15) and/or sensed data for the connection panel (14), the inverter (15), and/or the power distribution unit (15), and display a screen using the data. By checking the screen, the user can check the current power generation status even remotely.

However, as described above, although monitoring of the power generation status remotely may be possible, immediate response may be difficult when a problem occurs. For example, if a problem occurs in the inverter (15), the power transmitted to the external system may decrease rapidly. In particular, if the user does not check the state of the sudden decrease in power for a relatively long period of time, the period of power decrease is likely to last relatively long, resulting in a high possibility of economic loss.

FIG. 2 is a drawing for explaining a power management device according to one embodiment.

Referring to FIG. 2, a power management device (101) according to one embodiment may provide operating power to an inverter (15). For example, the inverter (15) may receive power from a solar panel (21), process it, and provide it to an external grid. The solar panel (21) may be implemented to include, for example, a single-crystal silicon solar cell, or may be implemented to include a multi-crystal silicon solar cell, and there is no limitation on its type. Single-crystal silicon solar cells and/or multi-crystal silicon solar cells may be connected to form a module, and a plurality of modules may form an array. The solar panel (21) of FIG. 2 may mean at least one of a solar cell, a module, or an array, and there is no limitation.

As described above, the inverter (15) can convert the direct current voltage provided from the solar panel (21) into an alternating current voltage and provide it to an external grid. The external grid may be, for example, a power purchaser, but there is no limitation.

In one example, the inverter (15) may be a central axis inverter. A central axis inverter is mainly used in large-scale solar power generation systems, and multiple solar panels can be connected to one inverter. A central axis inverter can convert DC power into AC power vertically through one central axis. A central axis inverter is relatively simple to install and maintain, and can operate efficiently in a large-scale power generation system.

In one example, the inverter (15) may be a distributed inverter (String Inverter). A distributed inverter may be mainly used in a small-scale solar power generation system. It is an inverter individually connected to each solar panel and can convert DC power generated from each panel into AC power. A distributed inverter is flexible in installation and may be suitable for a small-scale power generation system. In addition, since it has operational independence between individual panels, even if one panel has a problem, the other panels can operate normally.

In one example, the inverter (15) may be a multi-output inverter. A multi-output inverter may be an inverter that provides multiple independent AC outputs. Such an inverter may regulate multiple power outputs from a single inverter to meet various power requirements. A multi-output inverter may be applied to a variety of applications and may efficiently supply power to multiple power consumers.

In one example, the inverter (15) may be a transformerless inverter. A transformerless inverter may be an inverter that does not use a transformer when converting AC power. A transformerless inverter may have higher efficiency and a smaller size, and may be easy to install and maintain.

In one example, the inverter (15) may be a grid-tied inverter. A grid-tied inverter may be used to connect a solar power generation system to an electrical grid. A grid-tied inverter maintains voltage and frequency synchronization with the grid and may supply generated power to the grid or take power from the grid.

Meanwhile, the various types of inverters (15) described above can commonly convert direct current from a solar panel into alternating current. Meanwhile, when converting direct current into alternating current, operating power may be required. The power management device (101) according to the embodiment can provide operating power of the inverter (15). For example, the power management device (101) can include an input power interface for providing operating power to the inverter (15). The input power interface can be implemented as, for example, a 220V outlet (or, may be named a power socket), but there is no limitation on the form of implementation thereof. In addition, the power management device (101) can include a second power interface for connection to a wall power source. The input power interface can be implemented as, for example, a 220V outlet or a 220V plug, but there is no limitation on the form of implementation thereof. Accordingly, the power management device (101) can receive power from the wall power source and provide at least a portion of the received power to the inverter (15). The inverter (15) can operate using the power provided from the power management device (101), and can thus invert power from the solar panel (21) and output it to an external grid.

Meanwhile, the power management device (101) may receive sensing information of the solar processing devices including the inverter (15) and/or sensing information associated with each of the solar processing devices, or may be implemented to include a sensor for sensing. The power management device (101) may transmit the sensed information to the client. The client device (100) may display a first screen (103) associated with the power generation status based on the information received from the power management device (101). The first screen (103) may include current output power amount, power generation amount, power generation time, and/or accumulated power generation amount, but there is no limitation on the information. Alternatively, the client device (100) may display a second screen (104) based on the received information. The second screen (104) may include information associated with voltage (e.g., RST), current, active power, accumulated active power amount, frequency, operation status, and/or communication time, but there is no limitation.

In one example, the power management device (101) can check for an error in a specific hardware connected to the power management device (101). For example, assume that an error is detected in the inverter (105). The power management device (101) can control an internal switch to temporarily cut off power provided to the inverter (105) and then supply power again. Accordingly, the inverter (105) is temporarily not provided with operating power, and thus the inverter (105) can be turned off and then turned on again. Accordingly, the inverter (105) can be reset.

In one example, the power management device (101) may receive a reset command for specific hardware connected to the power management device (101) from the client device (100). For example, as illustrated in FIG. 2, the power management device (101) may transmit information to the client device (100). The client device (100) may display, for example, a first screen (103) or a second screen (104) based on the received information. Meanwhile, a user of the client device (100) may determine that an error related to the solar power system has occurred based on the first screen (103) or the second screen (104). Accordingly, the user may input a reset command for specific hardware (for example, an inverter (105)) through a UI provided by the client device (100). The client device (100) may transmit a reset command for specific hardware (for example, an inverter (105)) to the power management device (101). The power management device (101) can control an internal switch to temporarily cut off power provided to the specific hardware (e.g., inverter (105)) based on a reset command and then supply power again. Accordingly, the inverter (105) can be temporarily turned off and then turned on again because the inverter (105) is not provided with operating power. Accordingly, the inverter (105) can be reset.

In one example, the power management device (101) may identify an error related to power generation. The power management device (101) may determine to reset the identified hardware (e.g., the inverter (105)) according to, for example, priority. The power management device (101) may control an internal switch to temporarily cut off power provided to the inverter (105) and then provide power again. Accordingly, the inverter (105) may be temporarily deprived of operating power, and thus the inverter (105) may be turned off and then turned on again. Accordingly, the inverter (105) may be reset. If the error is continuously identified even after resetting the inverter (105), the power management device (101) may perform a reset on the next priority hardware as well.

In one example, the power management device (101) may receive a reset command for at least some of the hardware connected to the power management device (101) from the client device (100). For example, as illustrated in FIG. 2, the power management device (101) may transmit information to the client device (100). The client device (100) may display, for example, a first screen (103) or a second screen (104) based on the received information. Meanwhile, a user of the client device (100) may determine that an error related to the solar power system has occurred based on the first screen (103) or the second screen (104). Accordingly, the user may input a reset command through a UI provided by the client device (100). The client device (100) may transmit the reset command to the power management device (101). The power management device (101) can control an internal switch to temporarily cut off power provided to hardware (e.g., inverter (105)) determined according to priority based on a reset command and then supply power again. Accordingly, the inverter (105) is temporarily not provided with operating power, and thus the inverter (105) can be turned off and then turned on again. Accordingly, the inverter (105) can be reset. If an error is continuously confirmed even after resetting the inverter (105), the power management device (101) can also perform a reset on the next priority hardware.

FIG. 3 is a drawing for explaining a solar power system according to one embodiment.

A power management device (101) according to one embodiment may be connected to, for example, a connection box (301), an RTU (302), and/or an inverter (303).

For example, the power management device (101) can receive power from an external power source (e.g., AC 220 V) through the input power interface. In one example, an auto-recovery leakage circuit breaker (116) can be connected between the input power interface and the external power source, but this is exemplary and there is no limitation on whether the auto-recovery leakage circuit breaker (116) is connected and/or the type of the auto-recovery leakage circuit breaker (116). Power can be input to a power supply (115) (e.g., a Switching Mode Power Supply, SMPS) included in the power management device (101) through the input power interface. The power supply (115) can convert and/or process the received power into power suitable for, for example, the controller (114) and provide it. The controller (114) can operate based on the power provided from the power supply (115). The input power interface may be implemented to include, for example, a 220V outlet or a 220V plug, but there is no limitation on the implementation form. Accordingly, the power management device (101) can receive power from a wall power source through the input power interface.

Meanwhile, the power management device (101) may include a plurality of switches (121a, 121b, 121c, 121d, 121e). The plurality of switches (121a, 121b, 121c, 121d, 121e) may be connected to, for example, input power interfaces. Each of the plurality of switches (121a, 121b, 121c, 121d, 121e) may be connected to a plurality of output power interfaces (122a122b, 122c, 122d, 122e). For example, when each of the plurality of switches (121a, 121b, 121c, 121d, 121e) is in an on state, the input power interface can be connected to each of the plurality of output power interfaces (122a122b, 122c, 122d, 122e). Accordingly, a load connected to at least some of the plurality of output power interfaces (122a122b, 122c, 122d, 122e) can receive power from the wall power supply. Meanwhile, when some of the plurality of switches (121a, 121b, 121c, 121d, 121e) are in an off state, the electrical connection between the output power interface and the input power interface corresponding to the corresponding switch can be released. For example, when the fourth switch (121d) is in the off state, the fourth output power interface (122d) connected to the fourth switch (121d) and the input power interface may be electrically disconnected. Accordingly, the inverter (303) connected to the fourth output power interface (122d) may not receive power. Meanwhile, after a predetermined period of time has elapsed, the fourth switch (121d) may be controlled to be turned on again. In this case, the electrical connection between the fourth output power interface (122d) connected to the fourth switch (121d) and the input power interface may be restored (or, recovered). Accordingly, the inverter (303) connected to the fourth output power interface (122d) may receive power again. Accordingly, the inverter (303) may be turned on again when power is supplied after being turned off due to being temporarily not receiving power. Accordingly, the inverter (303) can perform a reset according to turn off-turn on.

If the inverter (303) supports a function of automatically turning on when power is supplied, the inverter (303) can perform a reset according to the power supply interruption and power supply resumption described above. If the inverter (303) does not support a function of automatically turning on after power is supplied, the controller (114) can provide a turn-on control signal to the inverter (303) through, for example, the terminal block (111). That is, the control for resetting the inverter (303) by the controller (114) can be organized as follows.

- First point in time: Turn-off signal output of the 4th switch (121d) corresponding to the inverter (303)

-Second point in time: Turn-on signal output of the 4th switch (121d) corresponding to the inverter (303)

-Third point (may be implemented to be omitted): Turn-on signal output of inverter (303)

Accordingly, the inverter (303) can be turned off after the first time point and before the second time point. The inverter (303) can be automatically turned on after the second time point, or can be turned on based on a turn-on signal generated at the third time point. Accordingly, the inverter (303) can be reset. Meanwhile, the first time difference between the first time point and the second time point can be set to, for example, a sufficient period of time so that the inverter (303) can be turned off. Depending on the implementation, the time difference between the first time point and the second time point can be set to be the same for each connected device, or can be set to be different. For example, the time difference between the time point of occurrence of the switch turn-off signal corresponding to the RTU (302) and the time point of occurrence of the switch turn-on signal, and the time difference between the time point of occurrence of the switch turn-off signal corresponding to the inverter (303) and the time point of occurrence of the switch turn-on signal, can be set to be the same for each connected device, or can be set to be different for each connected device.

Meanwhile, the second time difference between the second time point and the third time point may be set to, for example, a sufficient period of time for the inverter (303) to resume turning on after receiving power. Depending on the implementation, the time difference between the second time point and the third time point may be set to be the same for each connected device, or may be set to be different. For example, the time difference between the occurrence time of the switch turn-off signal corresponding to the RTU (302) and the occurrence time of the RTU (302) turn-on signal, and the time difference between the occurrence time of the switch turn-off signal corresponding to the inverter (303) and the occurrence time of the inverter (303) turn-on signal may be set to be the same for each connected device, or may be set to be different for each connected device.

Meanwhile, not only devices (301, 302, 303) independent from the power management device (101) may be connected to the output power interface, but also a device (e.g., LTE modem1) (304) implemented as at least a part of the power management device (101) may be connected to the output power interface. In one example, all of the output power interfaces (122a122b, 122c, 122d, 122e) may be implemented to be exposed outside the housing of the power management device (101), or in another example, some of the output power interfaces (122a122b, 122c, 122d, 122e) may be implemented to be located inside the housing. For example, the LTE modem1 (304) implemented to be located inside the housing of the power management device (101) may be implemented to be connected to the power interface (122b) located inside the housing, but there is no limitation.

For example, the status LED (112) can indicate the status of each connected device (or the status of power connected to the device), but there is no limitation. The management LCD (113) can output information related to the status of each connected device (or the status of power connected to the device), but there is no limitation. The controller (114) can be implemented with, for example, an MCU, a CPU, a GPU, an FPGA, etc., and there is no limitation in the form of implementation. The LTE modems connected to (or included in) the controller (114) can communicate with other LTE modems, and thus data can be transmitted/received. For example, the power management device (101) can perform, for example, LTE-based communication with an external remote access security system, but this is an example and there is no limitation.

In one example, the controller (114) can check for an error in a specific hardware connected to the power management device (101). For example, assume that an error is detected in the inverter (303). The controller (114) can control the internal switch (121d) to temporarily cut off power provided to the inverter (303) and then supply power again. Accordingly, the inverter (303) is temporarily not provided with operating power, and thus the inverter (303) can be turned off and then turned on again. Accordingly, the inverter (303) can be reset.

In one example, the controller (114) may receive a reset command for specific hardware connected to the power management device (101) from the client device (100). For example, as illustrated in FIG. 2, the power management device (101) may transmit information to the client device (100). The client device (100) may display, for example, a first screen (103) or a second screen (104) based on the received information. Meanwhile, a user of the client device (100) may determine that an error related to the solar power system has occurred based on the first screen (103) or the second screen (104). Accordingly, the user may input a reset command for specific hardware (for example, an inverter (303)) through a UI provided by the client device (100). The client device (100) may transmit a reset command for specific hardware (for example, an inverter (303)) to the power management device (101). The controller (114) may control the internal switch (121d) to temporarily cut off power provided to the specific hardware (e.g., inverter (303)) based on the reset command and then supply power again. Accordingly, the inverter (303) may be temporarily turned off and then turned on again because the inverter (303) is not provided with operating power. Accordingly, the inverter (303) may be reset.

In one example, the controller (114) may identify an error related to power generation. The controller (114) may decide to reset the identified hardware (e.g., inverter (303)) according to priority, for example. The controller (114) may control the internal switch (121d) to temporarily cut off power provided to the inverter (303) and then provide power again. Accordingly, the inverter (303) may be temporarily deprived of operating power, and thus the inverter (303) may be turned off and then turned on again. Accordingly, the inverter (303) may be reset. If the error is continuously identified even after resetting the inverter (303), the controller (114) may perform a reset on the next priority hardware as well.

In one example, the controller (114) may receive a reset command for at least some of the hardware connected to the power management device (101) from the client device (100). For example, as illustrated in FIG. 2, the power management device (101) may transmit information to the client device (100). The client device (100) may display, for example, a first screen (103) or a second screen (104) based on the received information. Meanwhile, a user of the client device (100) may determine that an error related to the solar power system has occurred based on the first screen (103) or the second screen (104). Accordingly, the user may input a reset command through a UI provided by the client device (100). The client device (100) may transmit the reset command to the power management device (101). The controller (114) can control the internal switch (121d) to temporarily cut off power provided to hardware (e.g., inverter (303)) determined according to priority based on the reset command and then supply power again. Accordingly, the inverter (303) is temporarily not provided with operating power, and thus the inverter (303) can be turned off and then turned on again. Accordingly, the inverter (303) can be reset. If an error is continuously confirmed even after resetting the inverter (303), the controller (114) can also perform a reset on the next priority hardware.

In one example, the power management device (101) may perform resets of each of the devices according to priority as described above, but this is exemplary. Depending on the implementation, the power management device (101) may perform resets of at least some of the connected devices simultaneously.

FIG. 4a illustrates a flowchart of an operation method of a power management device according to one embodiment.

In one embodiment, the power management device (101) can, in operation 401, perform monitoring of a plurality of devices. For example, the power management device (101) can monitor electrical characteristics (e.g., but not limited to, voltage, current, power, and/or impedance) of the plurality of connected devices (or output power interfaces corresponding to the devices). Alternatively, the power management device (101) can monitor the amount of power generated from the solar panel. Those skilled in the art will appreciate that in various embodiments of the present disclosure, monitoring of at least some of the plurality of devices can be replaced with monitoring the amount of power generated from the solar panel.

The power management device (101) may, in operation 403, determine whether an error is detected for a first device among the plurality of devices. For example, the power management device (101) may determine whether a condition indicating an error is satisfied in an electrical characteristic corresponding to the first device among the plurality of devices (e.g., voltage, current, power, and/or impedance, but not limited thereto). Alternatively, as described above, the power management device (101) may, instead of operation 403, determine whether an error is detected for the amount of power generated from the solar panel. If an error is not detected (403-No), the power management device (101) may continue to perform monitoring.

If an error is detected (403-Yes), the power management device (101) can, in operation 405, inquire of the client device whether to reset the first device. For example, the power management device (101) can transmit an inquiry message including identification information about the first device to the client device. In operation 407, the power management device (101) can receive a reset command for the first device. For example, the power management device (101) can receive a reset command from the client device. For example, the client device can output a UI for inquiring about whether to reset based on reception of the inquiry message. If the reset command for the first device is confirmed through the UI, the client device can transmit the reset command for the first device to the power management device (101).

The power management device (101) can control, in operation 409, the first power control module corresponding to the connection port of the first device to be turned off. Here, the connection port can be, for example, the output power interface described with reference to FIG. 3, and the first power control module can be, for example, the switch described with reference to FIG. 3, but there is no limitation on the implementation thereof. The power management device (101) can control, in operation 411, the first power control module corresponding to the connection port of the first device to be turned on. For example, the power management device (101) can output a control signal for turning off a switch, which is an example of the first power control module, and after a predetermined period of time has elapsed, output a control signal for turning on the switch, but this is exemplary and there is no limitation on the operation for reset.

As described above, the power management device (101) can perform a reset on a specific device according to a reset command for the specific device. Meanwhile, this is merely exemplary, and the power management device (101) may be implemented to simply transmit the monitoring result to the client device and perform a corresponding reset operation when a reset command for the first device is received from the client device. Meanwhile, as described above, in order to perform a reset on a specific device, the power management device (101) must store and/or manage information about which device is connected to which connection port (or, output power interface), and this will be described below.

FIG. 4b illustrates a flowchart of an operation method of a power management device according to one embodiment.

According to one embodiment, the power management device (101) can detect a connection to the first port in operation 421. The power management device (101) can check information related to the connection to the first port in operation 423. The power management device (101) can identify a device connected to the first port in operation 425. For example, the power management device (101) can store and/or manage associated information such as Table 1.

1st connection port Remote Access Security System Second connection port LTE Modem 3rd connection port RTU 4th connection port Inverter 5th connection port N/A

For example, the power management device (101) may, in operation 423, acquire, store, manage, and/or update information related to the connection of the first port based on user input. If the connection port is implemented as a USB type rather than a 220V interface, those skilled in the art will understand that the power management device (101) may acquire, store, manage, and/or update related information such as Table 1 based on type information based on the USB protocol.

Accordingly, the power management device (101) can identify a switch to be controlled for resetting a specific device by using the associated information as shown in Table 1. For example, if it is determined that a reset of the inverter is required, the power management device (101) can confirm that the inverter corresponds to the fourth connection port by using the associated information as shown in Table 1. The power management device (101) can reset the inverter by turning off the switch corresponding to the fourth connection port and turning on the switch after a predetermined period of time.

FIG. 4c illustrates a flowchart of an operation method of a power management device according to one embodiment.

According to one embodiment, the power management device (101) can detect a connection to the first port in operation 431. The power management device (101) can check power consumption related information based on the first port in operation 433. The power management device (101) can identify a device connected to the first port based on the power consumption related information based on the first port in operation 435. For example, the rated power consumption may be different for each device. For example, the first rated power consumption of the first device may be included in a first range, and the second rated power consumption of the second device may be included in a second range. The power management device (101) can, for example, check that the power consumption consumed in the first port is included in the first range. The power management device (101) can determine that a first device corresponding to a first range is connected to the first port, for example, based on whether power consumption consumed at the first port is included in a first range. The power management device (101) can determine that power consumption consumed at the first port is included in a second range, for example. The power management device (101) can determine that a second device corresponding to a second range is connected to the first port, for example, based on whether power consumption consumed at the first port is included in a second range.

Meanwhile, the method of confirming relationship information between the connection ports and connected devices described above with reference to FIG. 4b or FIG. 4c is merely exemplary, and those skilled in the art will understand that there is no limitation to the method of confirming relationship information of connected devices for each connection port as in Table 1.

FIG. 4d illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

According to one embodiment, the power management device (101) can perform monitoring of a plurality of devices in operation 461. The power management device (101) can determine whether an error has occurred in the first device based on the monitoring result in operation 463. Meanwhile, as described above, those skilled in the art will understand that operations 461 and 463 may be replaced with monitoring of information related to power generation of solar panels rather than monitoring the devices and determining whether an error has occurred based on the monitoring result. If no error has occurred (463-No), the power management device (101) can continue performing monitoring. If an error has occurred (463-Yes), the power management device (101) can control the first power control module corresponding to the connection port of the first device to be turned off in operation 465. Here, the connection port may be, for example, the output power interface described with reference to FIG. 3, and the first power control module may be, for example, the switch described with reference to FIG. 3, but there is no limitation on the implementation thereof. The power management device (101) may, in operation 467, control the first power control module corresponding to the connection port of the first device to be turned on. For example, the power management device (101) may output a control signal for turning off the switch, which is an example of the first power control module, and, after a predetermined period of time has elapsed, output a control signal for turning on the switch, but this is exemplary and there is no limitation on the operation for reset.

According to the above, the power management device (101) can perform a reset for a specific device according to a reset command for the specific device. In contrast to the embodiment of FIG. 4a, the power management device (101) can be configured to automatically perform the reset operation without a reset command from the client device. Meanwhile, if it is determined that an error still occurs even after performing the reset operation for the first device (or all devices), the power management device (101) can be configured to report the occurrence of an error to the client device.

FIG. 5 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

According to one embodiment, the power management device (101) can, in operation 501, monitor a power generation status. For example, the power management device (101) can monitor at least one piece of information (e.g., but not limited to, voltage, current, power, and/or impedance) associated with power generation provided from the solar panel. The power management device (101) can perform the monitoring based on information from a sensor that can sense information generated by a solar panel included in (or connected to) the power management device (101), but there is no limitation on the monitoring method.

According to one embodiment, the power management device (101) may, in operation 503, determine whether a power generation abnormality is detected based on the monitoring result. For example, the power management device (101) may determine, as a condition for the power generation abnormality, whether the amount of power provided from the solar panel decreases below a threshold amount, whether the length (or ratio) of time during which the amount of power is below a threshold amount exceeds a threshold amount (or a threshold ratio), and/or whether the reduction rate of the amount of power exceeds a threshold ratio, but there is no limitation on the type thereof. In operation 505, the power management device (101) may control the Nth power control module corresponding to the target device to be turned off based on the detection of the power generation abnormality. Here, the connection port may be, for example, the output power interface described with reference to FIG. 3, and the Nth power control module may be, for example, the switch described with reference to FIG. 3, but there is no limitation on the implementation thereof. In operation 507, the power management device (101) may control the Nth power control module corresponding to the target device to be turned on. For example, the power management device (101) may output a control signal to turn off a switch, which is an example of the Nth power control module, and after a predetermined period of time has elapsed, output a control signal to turn on the switch. However, this is an example and there is no limitation on the operation for reset.

The power management device (101) can check whether the reset for all devices is completed in operation 509. If the reset for all devices is not completed (509-No), the power management device (101) can change the target device to the next priority in operation 511. The power management device (101) can perform a reset operation on the changed target device. If the reset for all devices is completed (509-Yes), the power management device (101) can recheck whether there is a power generation abnormality in operation 513. If there is a power generation abnormality confirmed, the power management device (101) can perform an additional operation (e.g., reporting to a client device).

Meanwhile, in another embodiment, the power management device (101) may check whether a power generation abnormality is detected after performing a reset operation on one target device. If the power generation abnormality is still detected, the power management device (101) may change the target device to the next priority and perform a reset operation. If the power generation abnormality is no longer detected, the power management device (101) may stop changing and resetting the target device. For example, assume that the priorities are in the order of the first device -> second device -> third device. The power management device (101) may perform a reset operation on the first device based on the power generation abnormality. The power management device (101) may re-check whether a power generation abnormality exists for a specified period of time after the reset operation on the first device is completed. If a power generation abnormality is detected again after the reset on the first device, the power management device (101) may perform a reset operation on the second device, which is the next priority. The power management device (101) may re-check whether there is a power generation abnormality for a specified period of time after the reset operation for the second device is completed. If no power generation abnormality is detected after the reset for the first device, the power management device (101) may perform monitoring for power generation and may not perform any more reset operations.

FIG. 6A illustrates a flowchart for explaining an operating method of an electronic device according to one embodiment. The embodiment of FIG. 6A will be explained with reference to FIG. 6B. FIG. 6B is a diagram for explaining an artificial intelligence model according to one embodiment.

According to one embodiment, the power management device (101) can check weather information in operation 601. For example, the power management device (101) can obtain weather information input from a user or received based on LTE communication, and there is no limitation on the method of obtaining the information. The power management device (101) can check power generation-related information in operation 603. The power management device (101) can receive power generation-related information based on information from a sensor that can sense information generated by a solar panel included in (or connected to) the power management device (101), for example, and there is no limitation on the method of checking the information.

According to one embodiment, the power management device (101) may, in operation 605, determine whether there is a power generation abnormality based on weather information and power generation-related information. For example, the power management device (101) may input weather information and power generation-related information into an artificial intelligence model such as FIG. 6b. The artificial intelligence model may be trained to receive, for example, weather information and power generation-related information as input values and output whether there is an abnormality (or, abnormality probability). For example, when the weather is cloudy (or rainy), the possibility of a power generation abnormality may be low even if the power generation amount is relatively low. Or, when the weather is clear, the possibility of a power generation abnormality may be high even if the power generation amount is relatively high. Accordingly, the accuracy of determining whether there is a power generation abnormality based only on the power generation amount may be low. The power management device (101) may also determine whether there is a power generation abnormality using weather and power generation information based on, for example, an artificial intelligence model. As in FIG. 6b, the artificial intelligence model may determine whether there is an abnormality using weather information (for example, weather, amount of sunlight, but there is no limitation on the type) and power generation information. Meanwhile, the artificial intelligence-based abnormality determination is merely exemplary, and the power management device (101) can also determine whether power generation is abnormal based on rules.
