[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electric business in which electric power is transferred from a supply unit to a demand unit, in an electricity business with an imbalanced electric power corresponding to an excess or deficiency of a supply amount of the supply unit with respect to an amount of power received by the demand unit. The present invention relates to an imbalanced power trading support system for supporting a power trade.
[0002]
[Prior art]
As a result of the partial liberalization of the power market, electric utilities will either participate in tenders, etc. conducted by electric power companies (general electric utilities) and sell them to electric power companies as wholesale suppliers, or As a specific-scale electric utility, or as a specific-scale electric utility, a large-scale consumer subject to liberalization (special-scale customer: In principle, receive power from a 20KV special high-voltage transmission line with a usage scale of 2,000 KW or more) (Consumer).
Further, in the future, further liberalization of the electric power market is expected to make it possible to consign electric power retailing to consumers receiving high-voltage power of 50 KW or more and small-sized consumers such as ordinary households.
[0003]
In the liberalization of the electric power market as described above, at present, electric power companies will continue to operate the transmission line network centrally.
Therefore, the electric power company uses the existing transmission line network of the electric power company to transfer power to the customers, so from the viewpoint of ensuring the system stability of the transmission line network, it is necessary to follow the same amount of rules at the same time. is there.
[0004]
Note that the rule of the same simultaneous amount is that the amount of power received by the consumer (demand unit) from the transmission line network and the amount of power supplied by the generator (supply unit) to the transmission line network are measured for 30 minutes. Etc. must be matched within the prescribed period.
[0005]
Conventionally, as described above, in order to achieve the above-mentioned rule of the same amount of electricity, an electric power company that transfers power to a customer, as described above, receives electricity from a customer's transmission line network as a demand unit and generates electricity as a supply unit. In order to reduce the imbalance power to 0 using a computer system that manages the amount of power supplied to the transmission line network of the facility, the imbalance corresponding to the excess or deficiency of the power supply of the power generation facility with respect to the amount of power received by the customer. In some cases, the power is grasped and the power generation plan of the power generation equipment is corrected (for example, see Patent Documents 1 to 4).
[0006]
However, in such a method, it is necessary to adjust the output of the power generation equipment in accordance with fluctuations in the amount of power received by the customer, and the power generation cost increases due to a reduction in power generation efficiency of the power generation equipment and complicated load following control. Sometimes.
[0007]
Therefore, in many countries, a system in which the system operator adjusts the imbalance power, which is the deviation between the received power amount and the supplied power amount, as described above, is adopted in many countries. In particular, in the eastern United States, PJMs (Pennsylvania, New Jersey, Maryland, etc.) use the above-mentioned imbalanced power in the imbalanced market (a kind of real-time in which the grid operator adjusts the imbalanced power generated as a whole). Market).
[0008]
When procuring imbalanced power from the imbalanced market, in settlement with the imbalanced market, the amount of imbalanced power traded is calculated by subtracting the amount of power supplied from the amount of power received for each preset price setting period Multiplying the calculated transaction volume by the transaction price of imbalanced power set by the imbalanced market during the price setting period to calculate a clearing fee to be settled for the imbalanced power transaction; Is settled.
That is, when trading imbalanced power with the imbalanced market, it is necessary to grasp the power supply amount and the power reception amount for each price setting period in which the imbalanced transaction price is set.

[Problems to be solved by the invention]
However, in particular, a meter already installed in a small customer often measures or measures the amount of received power in a relatively long meter reading period, for example, every day or every month.
Therefore, in the electricity business that retails electricity to small customers whose received power is measured every relatively long meter reading period, when trading imbalanced power with the power market, It is difficult to trade and settle imbalanced power in response to short-period price fluctuations.
[0011]
In addition, as described above, when performing the transaction and settlement of imbalanced power for each relatively short price setting period, the measurement meter of the small customer needs to be able to measure the amount of received power for each of the price setting periods. It is necessary to measure the amount of power received by the customer for each of the above-mentioned price setting periods, such as by modifying or changing, and it is possible to secure profits in the above-mentioned electricity business by increasing the installation cost of metering meters and the cost of meter reading work. It will be difficult.
[0012]
Therefore, the present invention, in the electricity business as described above, for each pricing period shorter than the meter reading period, which is the timing of measuring the amount of power received by the customer, the transaction and settlement between the imbalanced electricity market and the electricity market. An object of the present invention is to realize an imbalanced power trading support system that enables the system.
[0013]
[Means for Solving the Problems]
In order to achieve this object, the first characteristic configuration of the imbalanced power trading support system according to the present invention is that, in an electric power business in which power is transferred from a supply unit to a demand unit, the power supply of the supply unit with respect to the amount of power received by the demand unit.

In the case of the specific demand section to which the meter reading data relating to the amount of power received in each meter reading period longer than the price setting period is input, the metering data alone cannot grasp the clearing received power data. However, according to the imbalanced power transaction support system having the first characteristic configuration, the metering data of the specific demand section and the standard price setting in the demand section of the specific demand section are provided by the liquidation receiving amount data deriving means. From the clearing profile data related to the amount of received power for each period, the amount of received power for clearing for the price setting period of the specific demand unit can be estimated. Then, the estimated power receiving amount data for clearing of the specific demand unit and the metering data itself of other demand units or the power receiving amount data for clearing derived from the meter reading data are integrated, and the pricing period of all demand units is set. It is possible to recognize the amount of received power for each.
[0015]
Therefore, as described above, the settlement receiving power data deriving means derives the settlement receiving power data, and sets the supply unit pricing period derived from the actual supply amount on the supply unit side or the supply amount planned on the previous day or the like. It is possible to calculate the clearing power supply data for each power supply amount, and to derive the transaction volume data for the transaction volume for each of the imbalanced power price setting periods with respect to the power market by the transaction volume data deriving means. Can be settled in the electric power market for each price setting period shorter than the meter reading period.
[0016]
The settlement profile data is data capable of recognizing the amount of received power for each standard price setting period in each of a plurality of demand section attribute categories such as home use, business use, and industrial use. This is set in the balanced electric power market, and as the settlement profile data, data that is disclosed on the Internet or the like by the one that manages the imbalanced electric power market can be used.

Therefore, for example, by using the settlement fee derived by the settlement means, settlement processing with the electric power market can be performed, or the settlement fee charged from the electric power market can be checked.
[0019]
The third characteristic configuration of the imbalanced power trading support system according to the present invention is, in addition to the second characteristic configuration, setting a power price for the supply unit or the demand unit using a settlement fee derived by the settlement unit. Power pricing means.
[0020]
That is, according to the imbalanced power transaction support system of the third characteristic configuration, the power price setting means charges at least a part of the settlement fee generated by the imbalanced power transaction to, for example, a demand unit. The electricity price for the supply unit or the demand unit by adding it to the electricity sales price for the supply unit or subtracting it from the purchase price paid for the supply unit. Increase in procurement cost due to the above can be suppressed.
[0021]
The fourth characteristic configuration of the imbalanced power trading support system according to the present invention, in addition to the first to third characteristic configurations, using planning profile data regarding the amount of power received for each predetermined planning period of the demand unit, Power demand and supply planning means for estimating the power receiving amount data for the power receiving amount for each of the planning periods of the demand unit, and performing a power supply and demand plan using the power receiving amount data for the plan,
The present invention is characterized in that there is provided planning profile data modifying means capable of modifying the planning profile data of the specific demand section using the transaction volume data derived by the transaction volume data deriving module.
[0022]
In other words, according to the imbalanced power trading support system of the fourth characteristic configuration, the power supply and demand planning means relates to the standard amount of power received by the demand unit for each predetermined period such as 5 minutes in the same manner as the settlement profile data. Using the planning profile data, the power receiving unit estimates the power receiving amount data relating to the power receiving amount for each planning period in the planning period such as the next day of each demand unit, and adjusts the supply unit according to the estimated power receiving amount data for planning. And a power supply and demand plan that determines the amount of power supply during the planning period. When the supply and demand plan is performed in this manner, the transaction amount data of the imbalanced power is determined to be due to the difference between the settlement received amount data and the planned received amount data of the specific demand part. The profile data for correction can be corrected by the profile data correction means so that the difference in the amount of received power is reduced. Therefore, in the power supply and demand planning means, the power supply and demand planning is performed so that the transaction amount of imbalanced power is as small as possible, and the imbalance power supply cost can be reduced.
[0023]
The fifth characteristic configuration of the imbalanced power trading support system according to the present invention is the above-described fourth characteristic configuration, in which the power supply and demand planning unit performs a power supply and demand plan using planning profile data corresponding to a time attribute category. Do
The point is that the planning profile data correcting means corrects the planning profile data corresponding to the time attribute section of the specific demand part based on the transaction volume.

That is, according to the imbalanced power trading support system of the fifth characteristic configuration, the received power of the demand unit varies according to the time attribute section such as a season or a day of the week. By performing power supply and demand planning using the corresponding profile data for planning, the received power data for planning can be accurately estimated. Further, when the planning profile data of the specific demand part is corrected by the planning profile data correction means, the planning profile data corresponding to the actual time attribute class of the planning target time is corrected, whereby the demand part is corrected. The accuracy of estimating the amount of received power can be further improved.
[0025]

On the other hand, with respect to the meter reading data of the specific customer D1 regarding the amount of received power for each month longer than the above-mentioned price setting period, the profiling processing means 45 uses the customer attribute classification of the specific customer D1 stored in the customer information DB 71. Recognized, and settlement profile data corresponding to the customer attribute category of the specific customer D1 is extracted from the profile DB 73 (step 105).
[0059]
Then, the profiling processing unit 45 adds the payment profile data corresponding to the customer attribute classification of the specific customer D1 extracted as described above to the monthly power reception amount recognized from the meter reading data of the specific customer D1. By multiplying the ratio of the amount of power received for one month in the profile data for clearing, the amount of power received by the specific customer D1 every 30 minutes is estimated (step 106), and the estimated time of the specific customer D1 for 30 minutes is estimated. Data indicating the amount of received power for each is acquired as the amount of received power for settlement (step 107).
[0060]
Then, the received power data for clearing relating to the received power for each 30 minutes in the clearing period of each customer D acquired by the received power data for clearing data deriving means 44 is totaled respectively, and the 30 minute data of all the customers D is collected. The data is transmitted to the market transaction server 60 as the total received power data for clearing relating to the total received power for each market (step 108), and is used in the market transaction server 60 for the market settlement processing for the power market.
[0061]
Further, in the power receiving management server 40, the power selling price set for each customer D is extracted from the power price DB 76 (step 109), and the power receiving amount for settlement of each customer D derived in step 107 above. From the data and the extracted power selling price for each customer D, a clearing fee to be charged to each customer D is derived (step 110). Then, a bill to be sent to each customer D is issued, the power rate is transmitted to the customer terminal 13, and the power rate is settled to each customer D such as the power rate charging process. (Step 111).
[0062]
Next, in the power supply side process executed by the power supply management server 50, as shown in FIG. 4, the meter reading means 52 communicates with the generator terminal 23 which automatically measures the measurement meter 21 of the generator S. By the communication, the so-called automatic meter reading in which the measurement data indicating the power supply amount of the generator S every 30 minutes is received by the communication unit 51 (step 201). Then, the measurement data of each power generator S is registered in the meter reading DB 74 (Step 202).
[0063]
In addition, the metering data for each generator S during the settlement period is read from the meter reading DB 74 by the settlement electricity supply amount data deriving means 53 from the meter reading DB 74 for each settlement period such as one month with the electricity market M. It is extracted as power supply amount data (step 203).
[0064]
Then, the power supply data for clearing indicating the power supply amount for each 30 minutes in the clearing period of each generator S acquired by the power supply data deriving means for clearing 54 is totaled, and the total of 30 The data is transmitted to the market transaction server 60 as the total electricity supply data for clearing indicating the total electricity supply amount per minute (step 204), and is used in the electric power market settlement processing for the electric power market in the market transaction server 60.
[0065]
Further, in the power supply management server 50, the power purchase price set for each generator S is extracted from the power price DB 76 (step 205), and the power supply amount for settlement of each generator S derived in step 203 is derived. A settlement fee to be paid to each generator S is derived from the data and the extracted power purchase price for each generator S (step 206). Then, issuance of a transaction statement to be sent to each generator S, transmission of the power rate to the generator terminal 23, and settlement of the power rate to each generator S, such as the transfer processing of the power rate, are performed. (Step 207).
[0066]
Next, in the market settlement process executed by the market transaction server 60, as shown in FIG. 5, at the end of the settlement period, the total received power data for settlement is acquired from the power reception management server 40 (step 301). Clearing power supply amount data is obtained from the power supply management server 50 (step 302).
[0067]
Then, the transaction amount data deriving means 62 subtracts the total power supply amount data for clearing from the total received power data for clearing, and calculates the transaction amount of imbalance power between the power market M and the power market M every 30 minutes during the clearing period. The transaction volume data shown is derived (step 303).
[0068]
Further, the settlement means 63 extracts the imbalanced electric power transaction price for each 30-minute price setting period in the settlement period published by the market server 31 from the electric power market DB 75 (step 304) and derived in the above step 303. From the transaction amount data and the extracted power transaction price, clearing fee data indicating a clearing fee every 30 minutes to be cleared within a clearing period with the power market M is derived (step 305). Then, a bill to be transmitted to the market server 31 of the power market M is issued, and a settlement process with the power market M is performed (step 306).
[0069]
Further, after the settlement fee data is derived in step 305, the settlement price to be paid to the electricity market M is stored in the electricity price DB by the electricity price setting means 64 so that the settlement fee falls within the profit range of the electricity business. The power selling price and the power purchase price may be modified or set (step 307).
[0070]
Further, the transaction amount data derived in step 303 is used by the planning profile data correcting means 55 of the power supply management server 50 for the planning profile data correcting process shown in FIG.
[0071]
That is, the planning profile data correction unit 55 acquires from the market transaction server 60 the transaction volume data indicating the transaction volume of the imbalance power every 30 minutes during the settlement period derived in the power market settlement process (step 401). ) From the transaction volume data, it is determined that the specific period when the transaction volume is equal to or more than the allowable transaction volume during the settlement period and the specific transaction volume at the specific period (step 402). That is, when the difference between the planning profile data used for estimating the planned received power amount of the specific customer D1 and the clearing profile data used for deriving the cleared received power amount exceeds an allowable level, It can be recognized as the above specific time, and the difference can be recognized as the above specific transaction amount.
[0072]
Time attribute divisions such as month, day of the week, and time zone of the above specific time are recognized (step 403), and based on past transaction volume data derived by the market transaction server 60, in the same time attribute division as the recognized time attribute division. The past actual transaction volume is extracted.
[0073]
Then, the singular transaction volume determined in step 402 is compared with the actual transaction volume (step 405). If the singular transaction volume is continuous, the imbalanced power transaction volume is increased. However, the planning profile data used to derive the planned receiving power data for the specific customer D1 is different from the clearing profile data used to derive the actual clearing receiving data. Assuming that there is a large difference, the planning profile data of the specific time attribute segment of the specific customer D1 is corrected so that the difference between the specific transaction amount and the actual transaction amount is reduced ( Step 406).
[0074]
Conversely, if the specific transaction volume is abrupt, it is determined that the increase in the imbalanced power transaction volume is not caused by the difference between the planning profile data and the clearing profile data. The process ends.
[0075]
[Another embodiment]
In the above-described embodiment, the transaction amount data deriving unit 62 subtracts the clearing power supply amount data indicating the actual power supply amount of the generator S from the clearing power reception amount data indicating the actual power reception amount of the customer D, The transaction amount data indicating the overall transaction amount of the imbalanced power is configured to be derived for each price setting period, and the settlement means 63 is configured to derive the overall clearing fee data using the transaction amount data. And a configuration for performing a clearing process with the power market M using the clearing charge data has been described. Separately, the transaction amount data deriving means 62 and the settlement means 63 will be described below. It may be configured as follows.
[0076]
That is, in another embodiment, at the end of a clearing period such as one month, the transaction amount data deriving means 62 includes the clearing received power data derived by the clearing received power data deriving means 44 and the clearing power supply data deriving means 53. Using the planned power receiving amount data and the planned power feeding amount data planned for the clearing period by the power supply and demand planning means 54 together with the clearing power feeding amount data derived in the above, the planned power receiving amount for the actual power receiving amount on the customer D side. The customer-side transaction volume data corresponding to the excess or deficiency of the power supply and the generator-side transaction volume data corresponding to the actual power supply deficiency with respect to the planned power supply on the generator S side are calculated for each price setting period. Is configured to be derived.
[0077]
That is, the transaction amount data deriving means 62 derives the customer-side transaction amount data by subtracting the planned power reception amount data from the settlement power reception amount data, and subtracts the clearing power supply amount data from the planned power supply amount data to generate the power generation. To derive transaction data on the client side.
[0078]
Next, the settlement means 63 calculates the imbalance power on the consumer D side from the consumer-side transaction volume data and the consumer-side transaction price set for the consumer D side with respect to the power market M. Of the customer-side settlement fee data indicating the settlement fee to be settled for the transaction of the above-mentioned transaction, and the generator set on the generator side between the generator-side transaction amount data and the electricity market M. From the side transaction price, generator-side settlement fee data indicating the settlement fee to be settled for the imbalanced power transaction on the generator S side is derived.
[0079]
Then, using the customer-side settlement fee data and the generator-side settlement fee data, separately performing the imbalance power transaction on the customer D side and the imbalance power transaction on the generator S side. Further, by performing the liquidation process in this manner, the transaction price of imbalanced power to the customer side and the transaction price of imbalanced power to the generator side can be set to different prices. .
