Background Art

[0002] The electricity market is composed of an operator who generates electricity (hereinafter referred to as a power generation operator), an operator who sells electricity to consumers (hereinafter referred to as a retail electricity operator), and an operator who operates the power system to perform power transmission and distribution from a power plant to consumers (hereinafter referred to as a power transmission and distribution operator).

Mode for Carrying Out the Invention

[0010] Hereinafter, a rate calculation device, a rate calculation system, a rate calculation method, and a rate calculation program according to an embodiment of the present disclosure will be described in detail with reference to the drawings.

[0011] Embodiment. Fig. 1 is a diagram showing a configuration example of a rate calculation system according to an embodiment.

[0012] As shown in FIG. 1, the charge calculation system 100 includes a charge calculation device 10, a transmission-related information management device 20, a system operation information management device 30, and a charge calculation condition setting device 40. The charge calculation device 10 is connected to the transmission-related information management device 20, the system operation information management device 30, and the charge calculation condition setting device 40 via a network (not shown). Note that the charge calculation device 10 may be directly connected to a part or all of the transmission-related information management device 20, the system operation information management device 30, and the charge calculation condition setting device 40. For example, the charge calculation device 10 may be directly connected to the charge calculation condition setting device 40 without going through the network.

[0013] Based on the information managed by the transmission-related information management device 20, the information managed by the system operation information management device 30, and the conditions set by the charge calculation condition setting device 40, the charge calculation device 10 calculates the charges that the power transmission and distribution utility operating the power system bills to the power generation utility and the retail electricity utility. Specifically, the charge calculation device 10 calculates the charges for the power generation utility and the retail electricity utility for the costs required for demand-supply adjustment and the charges for the power generation utility and the retail electricity utility for the costs required for congestion alleviation within the system.

[0014] The transmission-related information management device 20 is provided, for example, within the transmission system and manages various types of information related to the transmission service in the power system, i.e., transmission-related information. Examples of the transmission-related information managed by the transmission-related information management device 20 include transmission supply contract information, supply plan information, supply performance information, etc. The transmission supply contract information includes information on the utilities that have contracted for the transmission service, the operation plan for each generator formulated by each power generation utility, the demand assumption for each system formulated by each retail electricity utility, etc. The supply plan information indicates the planned generation value when the contractor is a power generation utility and the planned demand value when the contractor is a retail electricity utility. The supply performance information indicates the actual generation value when the contractor is a power generation utility and the actual demand value when the contractor is a retail electricity utility.

[0015] The system operation information management device 30 is provided, for example, within a system control system, and manages system operation information which is various types of information regarding the operation results of a power system. Examples of the system operation information managed by the system operation information management device 30 are system connection information, congestion handling results, supply-demand adjustment results, and the like. The system connection information is information regarding the power transmission paths from each generator connected to the power system to each consumer. The congestion handling results are the results of congestion handling implemented when a congestion state occurs in which the power transmission amount in a power transmission path is greater than the power transmission capacity of the path. Specifically, congestion handling is a process of performing, for example, power source substitution for switching the power source to be generated, output adjustment of the power source, etc., so that the power transmission amount becomes less than or equal to the power transmission capacity of the path, while enabling the necessary power to be sent to the consumers. For example, when generating power with a generator in region B and sending it to consumers in region A results in the power transmission amount exceeding the power transmission capacity of the path and causing a congestion state, the output of the generator in region B is reduced so that the power transmission amount becomes less than or equal to the power transmission capacity of the path, and the insufficient power is adjusted to be generated by a generator in region C that can send power to region A without passing through the location where the congestion state occurred. The congestion handling results are information indicating the content of the implemented congestion handling, and include, for example, the results of power source substitution implemented for congestion elimination, the results of output adjustment for each power source, and information on the location where congestion occurred. The results of output adjustment may be the results of adjustment power commands for instructing the generator to change its output. The supply-demand adjustment results are the results of supply-demand adjustment for eliminating an imbalance by adjusting the power generation amount when an imbalance occurs. Similar to congestion handling, supply-demand adjustment also performs power source substitution, output adjustment of the power source, and the like. Therefore, the supply-demand adjustment results include the results of power source substitution and the results of adjustment power commands for the generator.

[0016] The charge calculation condition setting device 40 sets the charge calculation conditions used when the charge calculation device 10 calculates the charges to be billed to the power generation business operator and the retail electricity business operator. Here, the charge to be billed is the charge for the costs incurred due to the implementation of the above-mentioned congestion handling and supply-demand adjustment. Examples of the charge calculation conditions set by the charge calculation condition setting device 40 are the charge claim distributions for each of the power generation business operator and the retail electricity business operator.

[0017] The charge calculation device 10 includes a consignment-related information acquisition unit 11, a system operation information acquisition unit 12, a supply-demand adjustment cost calculation unit 13, a congestion processing cost calculation unit 14, a supply-demand adjustment charge calculation unit 15, and a congestion processing charge calculation unit 16. The supply-demand adjustment cost calculation unit 13 and the supply-demand adjustment charge calculation unit 15 constitute a supply-demand adjustment charge determination unit 17, and the congestion processing cost calculation unit 14 and the congestion processing charge calculation unit 16 constitute a congestion processing charge determination unit 18.

[0018] The consignment-related information acquisition unit 11 acquires consignment-related information from the consignment-related information management device 20. The system operation information acquisition unit 12 acquires system operation information from the system operation information management device 30.

[0019] The supply-demand adjustment cost calculation unit 13 calculates the cost incurred by the power transmission and distribution operator for supply-demand adjustment (hereinafter referred to as the supply-demand adjustment cost) based on the information related to supply-demand adjustment among the information included in the consignment-related information and the system operation information, and the charge calculation conditions set by the charge calculation condition setting device 40. The information related to supply-demand adjustment used by the supply-demand adjustment cost calculation unit 13 in calculating the supply-demand adjustment cost is specifically the supply-demand adjustment performance information and the consignment supply contract information.

[0020] The congestion processing cost calculation unit 14 calculates the cost incurred by the power transmission and distribution operator for congestion processing (hereinafter referred to as the congestion processing cost) based on the information related to congestion processing among the information included in the consignment-related information and the system operation information, and the charge calculation conditions set by the charge calculation condition setting device 40. The information related to congestion processing used by the congestion processing cost calculation unit 14 in calculating the congestion processing cost is the system connection information, the congestion processing performance, and the consignment supply contract information.

[0021] The supply-demand adjustment charge calculation unit 15 determines the supply-demand adjustment charges to be billed to each of the power generation operator and the retail electricity operator based on the supply-demand adjustment cost calculated by the supply-demand adjustment cost calculation unit 13, the supply plan information, and the supply performance information.

[0022] The congestion processing charge calculation unit 16 determines the congestion processing charges to be billed to each of the power generation business operator and the retail electricity business operator based on the congestion processing costs calculated by the congestion processing cost calculation unit 14, the supply plan information, and the supply performance information.

[0023] Next, the operation of the charge calculation device 10 according to the present embodiment will be described.

[0024] FIG. 2 is a flowchart showing an example of the overall operation of the charge calculation device 10. The charge calculation device 10 executes the operation shown in FIG. 2 at a predetermined timing. For example, the charge calculation device 10 executes the operation shown in FIG. 2 at a determined cycle such as every 30 minutes.

[0025] The charge calculation device 10 first acquires system operation information and entrusted delivery-related information from the system operation information management device 30 and the entrusted delivery-related information management device 20 (step S1). In step S1, the charge calculation device 10 acquires the system operation information and the entrusted delivery-related information newly registered in the system operation information management device 30 and the entrusted delivery-related information management device 20 from the time of the previous execution of the operation shown in FIG. 2 to the current time. That is, the system operation information acquisition unit 12 of the charge calculation device 10 acquires the system operation information that has not been acquired in the past among the system operation information held by the system operation information management device 30, and the entrusted delivery-related information acquisition unit 11 acquires the entrusted delivery-related information that has not been acquired in the past among the entrusted delivery-related information held by the entrusted delivery-related information management device 20.

[0026] The charge calculation device 10 also acquires charge calculation conditions from the charge calculation condition setting device 40 (step S2).

[0027] Next, the charge calculation device 10 calculates the supply and demand adjustment charges for each demand BG (balancing group) and the supply and demand adjustment charges for each power generation BG based on the grid operation information and the consignment-related information acquired in step S1 and the charge calculation conditions acquired in step S2 (step S3). A demand BG is a unit that bundles a plurality of consumers to formulate a demand plan and is composed of one or more retail electricity suppliers. The calculation of the supply and demand adjustment charges is performed by the supply and demand adjustment charge determination unit 17. Details of the operation in which the supply and demand adjustment charge determination unit 17 of the charge calculation device 10 calculates the supply and demand adjustment charges for the demand BG and the power generation BG respectively will be described later.

[0028] Next, the charge calculation device 10 calculates the congestion handling charges for each demand BG and the congestion handling charges for each power generation BG based on the grid operation information and the consignment-related information acquired in step S1 and the charge calculation conditions acquired in step S2 (step S4). The calculation of the congestion handling charges is performed by the congestion handling charge determination unit 18. Details of the operation in which the congestion handling charge determination unit 18 of the charge calculation device 10 calculates the congestion handling charges for the demand BG and the power generation BG respectively will be described later.

[0029] Next, the operation of calculating the supply and demand adjustment charges in step S3 above will be described.

[0030] FIG. 3 is a flowchart showing an example of the operation in which the supply and demand adjustment charge determination unit 17 of the charge calculation device 10 calculates the supply and demand adjustment charges.

[0031] In the calculation of the supply and demand adjustment charges, first, the supply and demand adjustment cost calculation unit 13 acquires the supply and demand adjustment performance information, the consignment supply contract information, the supply plan information, and the supply performance information (step S11). Specifically, the supply and demand adjustment cost calculation unit 13 acquires the supply and demand adjustment performance information from the grid operation information acquired by the grid operation information acquisition unit 12 in step S1 of FIG. 2, and acquires the consignment supply contract information, the supply plan information, and the supply performance information from the consignment-related information acquired by the consignment-related information acquisition unit 11.

[0032] Next, the supply-demand adjustment cost calculation unit 13 calculates the cost performance of supply-demand adjustment based on the supply-demand adjustment performance information and the entrusted supply contract information, and apportions it based on the burden ratio between the demand side and the power generation side (step S12). Specifically, for each power source that contributed to the supply-demand adjustment, the supply-demand adjustment cost calculation unit 13 obtains the difference between the planned value and the actual value of power generation, multiplies the obtained difference by a unit price determined in advance, and calculates the supply-demand adjustment cost for each power source. The total of the supply-demand adjustment costs for each power source that contributed to the supply-demand adjustment is set as the cost performance of the supply-demand adjustment. In addition, the supply-demand adjustment cost calculation unit 13 divides the cost performance of the supply-demand adjustment into the cost burden of the supply-demand adjustment on the demand side (the demand-side burden portion of the adjustment cost performance) and the cost burden of the supply-demand adjustment on the power generation side (the power generation-side burden portion of the adjustment cost performance) according to a preset burden ratio. The above-mentioned "unit price" is determined when each power generation business operator contracts for the entrusted transmission service with the power transmission and distribution business operator and is included in the entrusted supply contract information. The above-mentioned "burden ratio" is set by the rate calculation condition setting device 40.

[0033] Next, the supply-demand adjustment charge calculation unit 15 calculates the difference between the demand planned value and the demand actual value for each demand BG, and the difference between the power generation planned value and the power generation actual value for each power generation BG based on the supply plan information and the supply performance information (step S13).

[0034] Next, the supply-demand adjustment charge calculation unit 15 calculates the supply-demand adjustment charge for each demand BG based on the demand-side burden portion of the adjustment cost performance and the difference between the demand planned value and the demand actual value for each demand BG obtained in step S13 (step S14). For example, if the demand-side burden portion of the adjustment cost performance is X, there are three groups of demand BGs, namely A, B, and C, and the differences between the demand planned values and the demand actual values of A, B, and C are Da, Db, and Dc respectively, the supply-demand adjustment charge calculation unit 15 sets the supply-demand adjustment charge for A as X×Da÷(Da + Db + Dc). The supply-demand adjustment charges for B and C are calculated in the same way.

[0035] Further, the supply-demand adjustment charge calculation unit 15 calculates the supply-demand adjustment charge for each power generation BG based on the power generation side's share of the actual adjustment cost and the difference between the planned power generation value and the actual power generation value for each power generation BG obtained in step S13 (step S15). The supply-demand adjustment charge calculation unit 15 calculates the supply-demand adjustment charge for each power generation BG in the same manner as in step S14.

[0036] Next, the operation of calculating the congestion handling charge in step S4 described above will be explained.

[0037] FIG. 4 is a flowchart showing an example of the operation in which the congestion handling charge determination unit 18 of the charge calculation device 10 calculates the congestion handling charge. The congestion handling charge determination unit 18 of the charge calculation device 10 repeats each of the processes in steps S21 to S25 shown in FIG. 4 for each congestion system. The congestion system is a partial system where congestion occurs. For example, it is a system within a defined range centered on the location where congestion occurs. When the power system is operated with one of the blocks obtained by dividing the power system into a plurality of parts as the smallest management unit, the block where congestion has occurred may be used as the congestion system.

[0038] In calculating the congestion handling charge, first, the congestion handling cost calculation unit 14 acquires the congestion handling performance information, system connection information, entrusted supply contract information, and supply plan information (step S21). Specifically, the congestion handling cost calculation unit 14 acquires the congestion handling performance information and system connection information from the system operation information acquired by the system operation information acquisition unit 12 in step S1 of FIG. 2, and acquires the entrusted supply contract information and supply plan information from the entrusted-related information acquired by the entrusted-related information acquisition unit 11.

[0039] Next, the congestion processing cost calculation unit 14 calculates the cost performance of congestion processing based on the congestion processing performance information and the entrusted supply contract information, and apportions it based on the burden ratio between the demand side and the power generation side (step S22). Specifically, for each power source that contributed to the congestion processing, the congestion processing cost calculation unit 14 obtains the difference between the planned value and the actual value of power generation, multiplies the obtained difference by a unit price determined in advance, and calculates the congestion processing cost for each power source. The sum of the congestion processing costs for all power sources that contributed to the congestion processing is set as the cost performance of the congestion processing. In addition, the congestion processing cost calculation unit 14 divides the cost performance of the congestion processing into the cost burden of the congestion processing on the demand side (the demand side burden portion of the congestion processing cost performance) and the cost burden of the congestion processing on the power generation side (the power generation side burden portion of the congestion processing cost performance) according to a preset burden ratio. The above-mentioned "unit price" is determined when each power generation business operator contracts for a transmission service with the power transmission and distribution business operator and is included in the entrusted supply contract information. The unit price used in step S12 above and the unit price used in step S22 above may be the same value or different values. The above-mentioned "burden ratio" is set by the rate calculation condition setting device 40. The burden ratio used in step S12 above and the burden ratio used in step S22 above may be the same value or different values.

[0040] Next, the congestion processing charge calculation unit 16 calculates the total value of the demand planned values for each demand BG and the total value of the power generation planned values for each power generation BG based on the supply plan information (step S23).

[0041] Next, the congestion processing charge calculation unit 16 calculates the congestion processing charge for each demand BG based on the demand side burden portion of the congestion processing cost performance and the total value of the demand planned values for each demand BG obtained in step S23 (step S24). For example, when the demand side burden portion of the congestion processing cost performance is Y, there are two groups of demand BGs, A and B, and the total values of the demand planned values for A and B are Ea and Eb respectively, the congestion processing charge calculation unit 16 sets the congestion processing charge for A as Y×Ea÷(Ea + Eb). The congestion processing charge for B is calculated in the same way.

[0042] Next, the congestion processing charge calculation unit 16 calculates the congestion processing charge for each power generation BG based on the power generation side's share of the actual congestion processing cost and the total value of the power generation plan values for each power generation BG obtained in step S23 (step S25). The congestion processing charge calculation unit 16 calculates the congestion processing charge for each power generation BG in the same manner as in step S24.

[0043] Note that one demand BG may be related to multiple congested systems, and one power generation BG may also be related to multiple congested systems. That is, among the congestion processing charges determined by executing steps S21 to S25 for each of the congested systems, there may be multiple cases where the destination demand BGs are the same, or there may be multiple cases where the destination power generation BGs are the same. Therefore, the congestion processing charge calculation unit 16 sums up those with the same destination demand BGs and also sums up those with the same destination power generation BGs to obtain the final congestion processing charges for each of the demand BG and the power generation BG.

[0044] Next, the hardware configuration of the charge calculation device 10 will be described. FIG. 5 is a diagram showing an example of the hardware that realizes the charge calculation device 10.

When the processor 101 operates as the delivery-related information acquisition unit 11 and the system operation information acquisition unit 12 to acquire delivery-related information and system operation information from the outside, the communication interface 104 is used. The communication interface 104 is also used when acquiring fee calculation conditions from the fee calculation condition setting device 40.

[0047] Note that the program for operating as the consignment-related information acquisition unit 11, the system operation information acquisition unit 12, the supply-demand adjustment cost calculation unit 13, the congestion processing cost calculation unit 14, the supply-demand adjustment fee calculation unit 15, and the congestion processing fee calculation unit 16, which is stored in the storage device 102, may be provided to a user or the like in a form written on a storage medium such as a CD (Compact Disc)-ROM or a DVD (Digital Versatile Disc)-ROM, or may be provided to a user or the like via a network.

That is, the fee calculation device 10 may be realized in a form including an electronic computer and a program executed by the electronic computer. Each function of the fee calculation device 10 may also be realized in a form in which a plurality of electronic computers operate in cooperation.

[0049] As described above, the fee calculation device 10 according to the present embodiment determines the supply-demand adjustment fee, which is the amount to be billed to each power generation company and each retail electricity company for the costs incurred in supply-demand adjustment, based on the supply-demand adjustment results by the power transmission and distribution company, the power generation planned value and the power generation actual value by the power generation company, and the demand planned value and the demand actual value by the retail electricity company. Further, the fee calculation device 10 determines the congestion processing fee, which is the amount to be billed to each power generation company and each retail electricity company for the costs incurred in congestion processing, based on the congestion processing results and the system connection information by the power transmission and distribution company, the power generation planned value by the power generation company, and the demand planned value by the retail electricity company.
