Based on the above embodiments of the energy storage system, FIG. 4 is a first schematic flowchart of a control method of the energy storage system provided by the embodiment of the present application. As shown in Figure 4, the control method includes the following steps:

Step 41, obtaining the current water temperature and the required temperature of the heating device.

In this solution, this solution is applied to the energy storage system in the above-mentioned embodiment, and based on the above-mentioned energy storage system, the control method of the energy storage system is implemented.

In this step, the temperature detection component detects the temperature of the water in the water tank, and the controller obtains the temperature detected by the temperature detection component and the required temperature of the heated device in real time, that is, the temperature that the heated device needs to reach.

In a possible implementation, the temperature sensor measures that the temperature of the water in the water tank is 65 degrees, and the controller obtains the temperature value and obtains that the required temperature of the heated device is 35 degrees.

In another possible implementation, the temperature sensor measures that the temperature of the water in the water tank is 65 degrees, and the controller obtains the temperature value and obtains that the required temperature of the heated device is 45 degrees.

Step 42. Adjust the power of the pump according to the current water temperature and the required temperature.

In this step, when the heating device needs to be heated, the water temperature in the water tank has reached a value that can provide heating. At this time, the hot water in the water tank is distributed to the heating device through the second pipe by using the principle of heat exchange , in order to increase the heating efficiency, it can be controlled by increasing the flow velocity in the second water pipe.

As an example, the heating device may be a crude oil barrel. In order to prevent the crude oil in the crude oil barrel from solidifying, it is necessary to continuously provide heat for the crude oil barrel, that is, the second water pipe serves as a heating coil of the crude oil barrel.

Optionally, the implementation of this step can be divided into the following steps:

Step 1. Determine the difference between the current water temperature and the required temperature according to the current water temperature and the required temperature;

In a possible implementation, the current water temperature is 65 degrees, the required temperature of the heated device is 35 degrees, and the difference at this time is 30 degrees.

In another possible implementation, the current water temperature is 65 degrees, the required temperature of the heated device is 45 degrees, and the difference at this time is 20 degrees.

Step 2. If the difference is greater than the preset threshold, adjust the power of the pump to the first preset power;

For example, the preset threshold can be set to 25 degrees. When the difference is greater than the threshold, it means that the heat receiving device does not need much heat, and the flow rate of the water in the second water pipe can be controlled to be low, that is, the power of the pump should not be adjusted too high. ; When the difference is less than or equal to the threshold, it means that the heat receiving device needs more heat, and the flow rate of the water in the second water pipe can be controlled to increase, that is, the power of the pump can be adjusted to increase.

In a possible implementation, 30 degrees is greater than 25 degrees, that is, the power of the pump is adjusted to a first preset power, for example, 20 kWh.

Step 3. If the difference is less than or equal to the preset threshold, adjust the power of the pump to the second preset power.

Wherein, the first preset power is smaller than the second preset power.

In another possible implementation, 20 degrees is less than 25 degrees, that is, the power of the pump is adjusted to a second preset power, for example, 30 kW h.

In this technical solution, the control of the energy storage system in the above embodiments is realized, so as to realize better energy supply for the heated device.

On the basis of the above embodiment of the control method of the energy storage system, Fig. 5 is a schematic flow diagram II of the control method of the energy storage system provided by the embodiment of the present application. As shown in Figure 5, the control method may also include the following steps:

Step 51 , acquiring the temperature from each temperature sensor.

In this solution, this solution is applied to the energy storage system in the above-mentioned embodiment, and based on the above-mentioned energy storage system, the control method of the energy storage system is realized.

In this step, since the energy source of the energy storage system is sunlight, and the position of the sun relative to the fixed point is constantly changing as time goes by, at this time, the temperature measured by each temperature sensor in the temperature sensor set passes through the first The temperature of the beam of the biconvex lens.

Among them, different temperature sensors represent different positions of the sun.

In a possible implementation, the temperature values obtained sequentially from the temperature sensor set are 23 degrees, 35 degrees, 45 degrees, 72 degrees, 46 degrees, and 30 degrees, and each temperature represents a different orientation of the sun and the energy storage system. It is the orientation of the spotlight component and the sun.

The controller obtains the temperature value corresponding to each sensor.

Step 52: Determine the orientation of the temperature sensor corresponding to the maximum temperature among the temperatures transmitted from each temperature sensor.

In this step, the maximum value is determined among the temperature values corresponding to each temperature sensor, and the orientation of the temperature sensor is obtained.

In a possible implementation, 72 degrees is greater than other temperature values, that is, the orientation of the temperature sensor corresponding to 72 degrees is the reference information needed to control the rotation of the motor.

Among them, the setting relationship between the orientation and the temperature sensor can be designed in advance, for example, the H temperature sensor corresponds to the angle between the sun and the ground of 30 degrees; the I temperature sensor corresponds to the angle between the sun and the ground of 60 degrees; the J temperature sensor corresponds to the angle between the sun and the ground The angle between the ground and the ground is 90 degrees; the K temperature sensor corresponds to the angle between the sun and the ground of 120 degrees; the L temperature sensor corresponds to the angle between the sun and the ground of 150 degrees.

Step 53: According to the orientation of the temperature sensor corresponding to the maximum temperature, control the motor to drive the heating part to rotate to a position where the light-collecting component and the incident angle of sunlight form an angle of 90 degrees.

In this step, after the temperature sensor corresponding to the maximum temperature value is determined, the motor is controlled to rotate the angle corresponding to the temperature sensor, so that the light concentrating component in the heating part of the energy storage system can fully obtain sunlight.

In a possible implementation, a temperature of 72 degrees corresponds to the J temperature sensor, and the J temperature sensor corresponds to an angle of 90 degrees between the sun and the ground. At this time, the motor drives the heating part to rotate until the concentrator is facing the sky, that is, the angle is 90 degrees. s position.

The control method of the energy storage system provided by the embodiment of the present application obtains the temperature transmitted by each temperature sensor, and then determines the position of the temperature sensor corresponding to the maximum temperature from the temperatures transmitted by each temperature sensor, and finally according to the temperature corresponding to the maximum temperature The orientation of the sensor is controlled by the motor to drive the heating part to rotate to a position where the condensing component and the incident angle of sunlight form an angle of 90 degrees.
