The performance information of the power storage device 20 includes, for example, a maximum charge capacity, a maximum output amount, a maximum charge amount, a current charge capacity (SOC: State Of Charge), a response time, and the like.
[0023] The market information storage unit 122 stores information (e.g., requirement information) about the electricity market and electricity products in the electricity market. The market information storage unit 122 stores trading information for each of a plurality of electricity markets, trading information for electricity products, etc. The plurality of electricity markets are different types of markets with different trading formats. The plurality of electricity markets include, for example, wholesale electricity trading markets (spot markets, hourly markets, and forward markets), supply and demand adjustment markets (primary, secondary (1), secondary (2), tertiary (1), and tertiary (2) electricity products), and capacity markets.
[0024] In addition, information (requirement information) regarding electricity products in the supply and demand adjustment market includes, for example, bidding time unit (3 hours, 30 minutes, etc.), response time (within 10 seconds, within 5 minutes, within 15 minutes, etc.), duration (5 minutes or more, 30 minutes or more, 3 hours, etc.), whether parallelization is required (mandatory or optional), command interval, monitoring interval, available supply amount, minimum bid amount, increment width, etc.
[0025] Here, the electricity market and types of electricity products will be described. The supply and demand adjustment market is a market for trading power adjustment capacity, and trades primary, secondary (1), secondary (2), tertiary (1), and tertiary (2) power products with different trading formats. The primary power product is called FCR (Frequency Containment Reserve) and is a product for trading primary adjustment capacity. The secondary (1) power product is called S-FRR (Synchronized Frequency Restoration Reserve) and is a product for trading secondary adjustment capacity (1). The secondary (2) power product is called FRR (Frequency Restoration Reserve) and is a product for trading secondary adjustment capacity (2).
[0026] The tertiary (1) electricity product is called RR (Replacement Reserve) and is a product that trades tertiary adjustment capacity (1).

The data utilization unit 134 is, for example, a Web processing unit accessible from the user terminal 30, and transmits various display information (various output information) to the user terminal 30 in response to a display request (output request) from the user terminal 30, and displays it on the display unit 33 of the user terminal 30.
[0039] The market bidding processing unit 40 executes bidding in each electricity market based on the bidding plans for the multiple electricity markets and electricity products that have been formulated. The market bidding processing unit 40 includes a market bidding management unit 41, a first market bidding unit 42-1, a second market bidding unit 42-2, a third market bidding unit 42-3, and a fourth market bidding unit 42-4.
[0040] In this embodiment, the first market bidding unit 42-1, the second market bidding unit 42-2, the third market bidding unit 42-3, and the fourth market bidding unit 42-4 refer to market bidding units in electricity markets with different transaction formats, and will be described as the market bidding unit 42 when referring to any market bidding unit included in the market bidding processing unit 40, or when no particular distinction is made. The market bidding units 42 have a similar configuration although they differ in the electricity markets and types of electricity products they handle.
[0041] 1, the market bid processing unit 40 corresponds to four different types of electricity markets, the first market bidding unit 42-1 to the fourth market bidding unit 42-4, but may be configured to correspond to N electricity markets, which may be three or less, or five or more. For example, if there are N electricity markets, the market bid processing unit 40 is assumed to include the first market bidding unit 42-1 to the Nth market bidding unit 42-N.
[0042] The market bidding management unit 41 adjusts and manages bids in all (all types of) corresponding markets (for example, bids by the first market bidding unit 42-1 to the fourth market bidding unit 42-4).
[0043] The first market bidding unit 42-1 executes bidding processing for, for example, the weekly commodity market (primary, secondary (1), secondary (2), and tertiary (1) electricity commodities) in the supply and demand adjustment market. The first market bidding unit 42-1 executes market bidding for transactions for the following week (transactions of four electricity commodities in the weekly commodity market) in the week before the delivery week.
[0044] The first market bidding unit 42-1 formulates a bidding plan for the weekly commodity market, taking into consideration the contract results of each electricity market up to the present time stored in the contract information storage unit 123, and executes bidding processing for the weekly commodity market based on the bidding plan.

[0058] Next, with reference to FIG. 2, the detailed configuration of the first market bidding section 42-1 (market bidding section 42) will be described. Fig. 2 is a functional block diagram showing an example of the first market bidding unit 42-1 in this embodiment. As described above, the first market bidding unit 42-1 is the market bidding unit 42 that executes bidding processing for, for example, the weekly commodity market (primary, secondary (1), secondary (2), and tertiary (1) electricity products) in the supply and demand balancing market. Each of the first market bidding unit 42-1 to the fourth market bidding unit 42-4 shown in Fig. 1 above has the same configuration (market bidding unit 42), and here, as an example, details of the first market bidding unit 42-1 that executes bidding processing for the weekly commodity market (primary, secondary (1), secondary (2), and tertiary (1) electricity products) in the supply and demand balancing market will be described.
[0059] As shown in Fig. 2, the first market bidding unit 42-1 includes a prediction processing unit 421, a market bidding planning unit 422, a bidding management unit 423, a first product bidding unit 424-1, a second product bidding unit 424-2, ..., and a fourth product bidding unit 424-4. Note that the third product bidding unit 424-3 and the fourth product bidding unit 424-4 are not shown in Fig. 2. Also, the detailed configuration of the second product bidding unit 424-2 and subsequent units is not shown.
[0060] The prediction processing unit 421 is included in each market bidding unit 42 (each of the first market bidding unit 42-1 to the fourth market bidding unit 42-4) and predicts the respective market prices (transaction prices). The prediction processing unit 421 of the first market bidding unit 42-1 shown in Fig. 2 predicts the transaction prices of each electricity product (primary, secondary (1), secondary (2), and tertiary (1) electricity product) in the weekly commodity market of the supply and demand balancing market. The prediction processing unit 421 predicts the transaction prices based on, for example, weather forecast information acquired from the external server 2, past transaction price information, etc.
[0061] The predicted value of the transaction price includes a predicted price distribution that indicates the probability distribution of the predicted value of the transaction price. Details of the predicted price distribution will be described later with reference to FIG. The prediction processing unit 421 stores the predicted trading price values of the respective electricity products in the prediction information storage unit 124. Furthermore, the prediction processing unit 421 may predict the predicted value of the transaction price according to the bidding unit of the electricity product, for example.
[0062] The market bidding planning unit 422 creates a bidding plan for each electricity commodity in the weekly commodity market based on the predicted value of the transaction price in each electricity market predicted by the prediction processing unit 421, and creates an overall bidding plan (initial) for all of the products subject to bidding. The overall bidding plan also includes the bidding order of the products subject to bidding. The market bidding planning unit 422 creates a bidding plan for the electricity market for the electricity storage device 20 based on, for example, the predicted value of the transaction price, the contract results of electricity transactions concluded in each electricity market, and management device information related to the electricity storage device 20 to be managed. In addition, the market bidding planning unit 422 creates a bidding plan according to the bidding unit of the electricity product.
[0063] The market bidding planning unit 422 formulates an overall bidding plan so that the expected profit based on the predicted price distribution is equal to or greater than a certain value. Details of the expected profit will be described later with reference to FIGS.
[0064] The market bidding planning unit 422 stores the overall bidding plan in the bidding plan memory unit 125 and transmits it to the bidding planning units 425 of each bidding target product (first product bidding unit 424-1, second product bidding unit 424-2, ..., and fourth product bidding unit 424-4) via the bidding management unit 423.
[0065] The market bid planning unit 422 may select one type of a plurality of power products and create a bidding plan, or may create a bidding plan that combines a plurality of power products. For example, the market bid planning unit 422 may create bidding plans for different power products in different time periods, or may create a bidding plan that combines a plurality of power products in consideration of the response time of the requirement information. For example, when bidding for two power products, the market bid planning unit 422 may create a bidding plan that leaves a gap between the response times.
[0066] The bid management unit 423 manages the bidding plan planning process and bidding process of the market bidding unit 42. The bid management unit 423 of the first market bidding unit 42-1 shown in Fig. 2 manages the bidding plan planning process and bidding process for the weekly commodity market (primary, secondary (1), secondary (2), and tertiary (1) electricity commodities). The bid management unit 423 acquires the overall bidding plan planned by the market bidding planning unit 422 and transmits it to the bidding planning unit 425 of each commodity subject to bidding (first commodity bidding unit 424-1, second commodity bidding unit 424-2, ..., and fourth commodity bidding unit 424-4).
[0067] Furthermore, the bidding management unit 423 stores the contract result acquired by the contract result acquisition unit 427 (described later) in the contract information storage unit 123, and transmits it to the market bidding unit 42 of the next electricity market.
[0068] In this embodiment, the first commodity bidding unit 424-1, the second commodity bidding unit 424-2, ..., and the fourth commodity bidding unit 424-4 refer to commodity bidding units for electricity commodities with different transaction formats, and will be described as the bidding processing unit 424 when referring to any market bidding unit provided in the first market bidding unit 42-1, or when no particular distinction is made.
[0069] 2 shows an example in which the market bidding unit 42 corresponds to four different types of electricity products, the first commodity bidding unit 424-1 to the fourth commodity bidding unit 424-4. However, the market bidding unit 42 may be configured to correspond to M number of electricity products, which may be three or less, or five or more. For example, if there are M number of electricity products, the market bidding unit 42 is assumed to include the first commodity bidding unit 424-1 (first bid processing unit 424) to the M-th commodity bidding unit 424-M (M-th bid processing unit 424). Furthermore, if the concept of electricity products does not exist in the electricity market, M may be 1 (M=1). In this case, the market bidding unit 42 is assumed to include one bid processing unit 424 corresponding to the first commodity bidding unit 424-1.
[0070] 2, the first commodity bidding section 424-1 corresponds to the first electricity commodity in the weekly commodity market of the supply and demand adjustment market, the second commodity bidding section 424-2 corresponds to the second (1) electricity commodity in the weekly commodity market of the supply and demand adjustment market, the third commodity bidding section 424-3 corresponds to the second (2) electricity commodity in the weekly commodity market of the supply and demand adjustment market, and the fourth commodity bidding section 424-4 corresponds to the tertiary (1) electricity commodity in the weekly commodity market of the supply and demand adjustment market.
[0071] Each of the bidding processing units 424 (first product bidding unit 424-1 to fourth product bidding unit 424-4) includes a bidding planning unit 425, a bidding execution unit 426, and a contract result acquisition unit 427. The bidding plan unit 425 creates (modifies) a bidding plan for the corresponding electricity product (corresponding product) based on the overall bidding plan (initial), the contract results in other markets (if there is a market in which a contract was made earlier), and the contract results of other products in other markets (if there is a product to be bid that was made earlier). The bidding plan unit 425 stores the created (modified) bidding plan in the bidding plan storage unit 125.
[0072] The bidding execution unit 426 executes bidding processing for the corresponding product based on the bidding plan created by the bidding plan unit 425. The bidding execution unit 426 executes bidding processing for the corresponding product based on the bidding plan stored in the bidding plan storage unit 125, for example.
[0073] The agreement result acquisition unit 427 acquires the agreement results of the corresponding products for which the bidding unit 426 has placed a bid from the external server 2. The agreement result acquisition unit 427 transmits the acquired agreement results of each electricity product to (the bidding planning unit 425 of) the next bidding processing unit 424. When all bidding for the products subject to bidding by the market bidding unit 42 has been completed, the agreement result acquisition unit 427 transmits the acquired agreement results to the market bidding unit 42 of the next electricity market via the bid management unit 423.
[0074] 2, the first commodity bidding unit 424-1 includes a bidding planning unit 425-1, a bidding execution unit 426-1, and a contract result acquisition unit 427-1, and executes bidding processing for primary electricity products in the weekly commodity market. The first commodity bidding unit 424-1 also transmits the acquired contract results to the second commodity bidding unit 424-2.
[0075] The second commodity bidding unit 424-2 includes a bidding planning unit 425-2, a bidding execution unit 426-2, and a contract result acquisition unit 427-2, and executes bidding processing for secondary (1) electricity products in the weekly commodity market. The second commodity bidding unit 424-2 also transmits the acquired contract results to the third commodity bidding unit 424-3 (not shown).
[0076] The third commodity bidding unit 424-3 (not shown) includes a bidding planning unit 425-3 (not shown), a bidding execution unit 426-3 (not shown), and a contract result acquisition unit 427-3 (not shown), and executes bidding processing for secondary (2) electricity products in the weekly commodity market. The third commodity bidding unit 424-3 (not shown) transmits the acquired contract results to the fourth commodity bidding unit 424-4.
[0077] The fourth commodity bidding unit 424-4 includes a bidding planning unit 425-4, a bidding execution unit 426-4, and a contract result acquisition unit 427-4, and executes bidding processing for the tertiary (1) electricity commodity in the weekly commodity market. The fourth commodity bidding unit 424-4 also transmits the acquired contract results to the next market bidding unit 42 (the second market bidding unit 42-2).
[0078] The bidding planning unit in this embodiment corresponds to the market bidding planning unit 422 and the bidding planning unit 425 described above. The bidding planning unit (market bidding planning unit 422 and bidding planning unit 425) formulates a bidding plan based on the predicted value of the transaction price for each electricity commodity, the contract result of the electricity transaction for each electricity commodity, the requirement information (demand adjustment duration, response time, etc.) included in each electricity commodity, and the management device information. Furthermore, the bidding planning unit (market bidding planning unit 422 and bidding planning unit 425) determines planned bidding information including the electricity commodity for which bidding is planned, price, time period, and bid amount as a bidding plan based on the predicted value of the transaction price for each electricity commodity, the contract result, the requirement information, and the management device information.
[0079] Furthermore, the above-mentioned bidding execution unit 426 executes bidding processing for the corresponding product based on, for example, the bidding plan information.
[0080] 2, the configuration of the first market bidding unit 42-1 has been described, but the market bidding units 42 of other markets, that is, the second market bidding unit 42-2, the third market bidding unit 42-3, and the fourth market bidding unit 42-4, have the same configuration and are provided with M bid processing units 424. Here, "M", the number of bid processing units 424, varies depending on the number of electricity products available in the corresponding electricity market. Note that a market bidding unit 42 corresponding to an electricity market in which the concept of electricity products does not exist, is provided with (M=1) bid processing units 424.
[0081] Specifically, since the second market bidding unit 42-2 and the fourth market bidding unit 42-4 do not have the concept of electricity commodities, the second market bidding unit 42-2 and the fourth market bidding unit 42-4 (market bidding unit 42) include a prediction processing unit 421, a market bid planning unit 422, a bid management unit 423, and one bid processing unit 424. The bid processing unit 424 corresponds to the spot market or the one-hour-ahead trading market, and includes a bid planning unit 425, a bid execution unit 426, and a contract result acquisition unit 427 that correspond to the spot market or the one-hour-ahead trading market.
[0082] Furthermore, since the third market bidding unit 42-3 handles one type of electricity product (tertiary (2) electricity product), the third market bidding unit 42-3 (market bidding unit 42) includes a prediction processing unit 421, a market bid planning unit 422, a bid management unit 423, and one bid processing unit 424. The bid processing unit 424 corresponds to the tertiary (2) electricity product, and includes a bid planning unit 425, a bid execution unit 426, and a contract result acquisition unit 427 that correspond to the tertiary (2) electricity product.
[0083] Next, the predicted price distribution in this embodiment will be described with reference to FIG. FIG. 3 is a diagram showing an example of a probability distribution of predicted values of trading prices in this embodiment. The example shown in Figure 3 shows an example of the probability distribution of predicted values of trading prices in the spot market.
[0084] The graph shown in Figure 3(a) shows a price curve of the predicted price in the spot market predicted by the prediction processing unit 421 of the second market bidding unit 42-2. The horizontal axis of the graph shows the number of 30-minute segments into which one day (24 hours) is divided, and the vertical axis shows the predicted value of the price (transaction price).
[0085] In Figure 3(a), waveform W1 shows a price curve of the predicted average value, waveform W2 shows a price curve of the average value +1σ (σ is the standard deviation), waveform W3 shows a price curve of the average value -1σ, waveform W4 shows a price curve of the average value +2σ, and waveform W5 shows a price curve of the average value -2σ.
[0086] The prediction processing unit 421 predicts the predicted mean value and standard deviation (σ), and generates a price distribution as shown in Figures 3(b) to 3(d) based on the predicted mean value and standard deviation (σ). In the graphs shown in Figures 3(b) to 3(d), the horizontal axis represents price (yen / kWh (kilowatt hour)), and the vertical axis represents the occurrence probability of that price.
[0087] Waveform W6 shown in Figure 3(b) shows the price distribution when the average price is 10.00 (yen / kWh) and the standard deviation (σ) is 1.00. Waveform W7 shown in Figure 3(c) shows the price distribution when the average price is 9.00 (yen / kWh) and the standard deviation (σ) is 6.00. Waveform W8 shown in Figure 3(d) shows the price distribution when the average price is 20.00 (yen / kWh) and the standard deviation (σ) is 4.00.
[0088] Next, details of expected profits in this embodiment will be described with reference to Figures 4 and 5. Here, expected profits and losses in the spot market and the supply and demand adjustment market will be described. In addition, spot market transactions include purchase transactions for purchasing (charging) electricity and sales transactions for selling (discharging) electricity. The transaction amount in the spot market is expressed by the following formula (1).
[0089]
number
[0090] Furthermore, transactions in the supply and demand adjustment market are supply transactions that supply (discharge) adjustment power, and the transaction amount in the supply and demand adjustment market is expressed by the following formula (2).
[0091]
number
[0092] FIG. 4 is a diagram illustrating an example of expected profit and loss in the spot market in this embodiment. Waveform W9 in Figure 4(a) shows the price distribution for frames sold in the spot market (high-priced frames), while waveform W10 in Figure 4(b) shows the price distribution for frames purchased in the spot market (low-priced frames).
[0093] In this case, the transaction profit / loss value is the difference between the transaction amount (sales) and the transaction amount (purchase), and is expressed by the following formula (3).
[0094]
number
[0095] The profit and loss probability is the product of waveforms W9 and W10, and is expressed by waveform W11 shown in Figure 4(c), which is generated by performing convolution. The profit and loss distribution is expressed by the following equation (4).
[0096]
number
[0097] The horizontal axis of the graph shown in FIG. 4(c) represents the profit or loss calculated by equation (3), and the vertical axis represents the profit or loss probability (probability of profit or loss occurring) calculated by equation (3). Moreover, waveform W12 shown in Figure 4(d) is a shaped version of waveform W11 shown in Figure 4(c), and the profit / loss of X (%) in VaR (Value at Risk) is the profit / loss value at the point where the sum of the probabilities from the higher profit / loss of waveform W12 becomes X (%), and is intended to be the profit / loss in the event of a downside deviation. Furthermore, expected profit / loss is expressed by the following formula (5).
[0098]
number
[0099] In this way, in the spot market, the market bidding planning unit 422 and the bidding planning unit 425 calculate the expected profit and loss using the above formula (1) and formulas (3) to (5), and create a bidding plan so that the expected profit and loss is equal to or greater than a certain value, preferably so that the expected profit and loss (expected profit) is maximized. In addition, a condition may be that the profit and loss of X% in VaR is equal to or greater than a certain value.
[0100] FIG. 5 is a diagram illustrating an example of expected profit and loss in the supply and demand adjustment market in this embodiment. Waveform W13 shown in Figure 5(a) shows the price distribution of the predicted trading price (supply price) in the balancing market. The horizontal axis of the graph shown in Figure 5(a) shows the trading price (yen / kWh) in the balancing market, and the vertical axis shows the occurrence probability. In the example shown in FIG. 5(a), the black circle (●) indicates the upper limit price in the supply and demand adjustment market (a contract will be executed / triggered if it is below XX yen).
[0101] Moreover, waveform W14 shown in Fig. 5(b) represents the cumulative distribution obtained by integrating the probability of waveform W13. The horizontal axis of the graph shown in Fig. 5(b) represents the trading price (yen / kWh) in the supply and demand adjustment market, and the vertical axis represents the cumulative probability. The black circles (●) in Figure 5(b) indicate the upper limit in the balancing market, and the probability of execution at a price below the black circle (●) (expected profit / loss) is the product of the price and cumulative probability. The expected profit / loss in the balancing market is expressed by the following formula (6) or formula (7).
[0102]
number
[0103]
number
[0104] In this way, in the supply and demand adjustment market, the market bidding planning unit 422 and the bidding planning unit 425 calculate the expected profit and loss using the above formula (2) and formula (6) or formula (7), and formulate a bidding plan so that the expected profit and loss is equal to or greater than a certain value, and preferably so that the expected profit and loss (expected profit) is maximized.
[0105] Next, the operation of the energy trading management system 1 according to this embodiment will be described with reference to the drawings. FIG. 6 is a diagram illustrating an outline of the operation of the energy trading management system 1 according to this embodiment.
[0106] 6, in the energy trading management system 1, first, the market information management unit 131 outputs market information and commodity information to the market bidding processing unit 40 (step S11). The market information management unit 131 outputs the market information and commodity information acquired from the external server 2 via the NW communication unit 11, and the market information and commodity information stored in the market information storage unit 122, to the market bidding processing unit 40.
[0107] Next, the market bid processing unit 40 outputs the agreement result to the charge / discharge plan formulation unit 132 (step S12). The market bid processing unit 40 formulates bidding plans for a plurality of electricity markets and a plurality of electricity products, and executes bidding processes for the plurality of electricity markets and a plurality of electricity products based on the formulated bidding plans. The market bid processing unit 40 acquires the bidding agreement result from the external server 2 via the NW communication unit 11, and outputs the agreement result to the charge / discharge plan formulation unit 132.
[0108] Next, the charge and discharge plan formulation unit 132 outputs the operation plan to the monitoring and control unit 133 (step S13). The charge and discharge plan formulation unit 132 formulates a charge and discharge plan for the power storage device 20 based on the agreement result acquired from the market bidding processing unit 40, and outputs the formulated charge and discharge plan as an operation plan to the monitoring and control unit 133. The charge and discharge plan formulation unit 132 stores the formulated charge and discharge plan in the charge and discharge plan storage unit 126.
[0109] Next, the monitoring control unit 133 transmits the control command value to the power storage device 20 (step S14). The monitoring control unit 133 generates a control command value for controlling the charging and discharging of each power storage device 20 based on the charging and discharging plan (operation plan) formulated by the charging and discharging plan formulation unit 132, and transmits the generated control command value to the power storage device 20.
[0110] Next, the monitoring control unit 133 acquires the actual value from the power storage device 20 (step S15). The monitoring control unit 133 acquires the actual value of the charge / discharge control from each power storage device 20, and stores the actual value in the actual value storage unit 127.
[0111] Next, the data utilization unit 134 transmits the report information to the user terminal 30 (step S16). For example, in response to an output request from the user terminal 30, the data utilization unit 134 generates various reports (output information) using the performance values stored in the performance value storage unit 127, the market information and product information stored in the market information storage unit, and the charge / discharge plan stored in the charge / discharge plan storage unit 126, and transmits the report information to the user terminal 30 via the NW communication unit 11. The user terminal 30 displays the received report information (various reports) on the display unit 33.
[0112] Next, bidding processing for multiple electricity markets by the energy trading management system 1 according to this embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing an example of bidding processing for multiple electricity markets in the energy trading management system 1 according to this embodiment.
[0113] As shown in Fig. 7, in the energy trading management system 1 of this embodiment, the market bidding processing unit 40 executes a process of predicting market prices (trading prices) for all markets where trading is possible (step S101). The market bidding processing unit 40 causes the prediction processing unit 421 of each market bidding unit 42 to predict the market price of each electricity market. Each prediction processing unit 421 generates a predicted price distribution of market prices (trading prices), for example, as shown in Fig. 3, and stores it in the prediction information storage unit 124.
[0114] Next, the market bidding planning unit 422 and the bidding planning unit 425 of each market bidding unit 42 create a bidding plan for the electricity market based on the current contract information and the predicted price (step S102). The market bidding planning unit 422 and the bidding planning unit 425 create a bidding plan for the corresponding electricity market based on the predicted price distribution of the market price (transaction price), for example, so as to maximize the expected profit and loss. The market bidding planning unit 422 and the bidding planning unit 425 store the created bidding plan in the bidding plan storage unit 125.
[0115] Next, the market bid processing unit 40 determines whether or not a bidding plan exists for the first market (step S103). The market bid processing unit 40 determines whether or not a bidding plan exists using the bid management unit 423 of the first market bidding unit 42. If a bidding plan exists for the first market (step S103: YES), the market bid processing unit 40 proceeds to step S104. If a bidding plan does not exist for the first market (step S103: NO), the market bid processing unit 40 proceeds to step S108.
[0116] In step S104, the bidding execution unit 426 of the market bidding unit 42 executes bidding processing based on the bidding plan. The bidding execution unit 426 executes bidding processing based on, for example, the bidding plan of the electricity market stored in the bidding plan storage unit 125.
[0117] Next, the contract result acquisition unit 427 of the market bidding unit 42 acquires the contract result (step S105). The contract result acquisition unit 427 stores the acquired contract result in the contract information storage unit 123.
[0118] Next, the market bid processing unit 40 executes a process of re-predicting the market price (step S106). When the predicted market price changes as a result of a contract or due to a change in the market, the market bid processing unit 40 executes a process similar to the process of step S101 described above, and executes a process of re-predicting the market price at which trading is still possible.
[0119] Next, the market bidding planning unit 422 and the bidding planning unit 425 of each market bidding unit 42 create a bidding plan for the electricity market based on the current contract information and the predicted price (step S107). The market bidding planning unit 422 and the bidding planning unit 425 execute the same process as the process of step S101 described above to create a bidding plan for the electricity market.
[0120] Next, in step S108, the bid management unit 423 of the market bidding unit 42 determines whether there is a next market (or product). The bid management unit 423 determines whether there is a next electricity market or electricity product available for bidding. If there is a next electricity market or electricity product available for bidding (step S108: YES), the bid management unit 423 returns the process to step S104. If there is no next electricity market or electricity product available for bidding (step S108: NO), the bid management unit 423 proceeds to step S109.
[0121] In step S109, the charge / discharge plan formulation unit 132 formulates an operation plan for the power storage device 20 based on all the agreement results. The charge / discharge plan formulation unit 132 formulates an operation plan (charge / discharge plan) for the power storage device 20 based on, for example, all the agreement results before activation stored in the agreement information storage unit 123. The charge / discharge plan formulation unit 132 stores the formulated charge / discharge plan in the charge / discharge plan storage unit 126.
[0122] Next, the monitoring control unit 133 outputs a control command value for controlling charging and discharging of each power storage device 20 based on the operation plan (charge and discharge plan) formulated by the charge and discharge plan formulation unit 132 (step S110). The monitoring control unit 133 generates a control command value based on the charge and discharge plan stored in the charge and discharge plan storage unit 126, for example, and outputs the generated control command value to the power storage device 20. After the processing of step S110, the monitoring control unit 133 ends the processing.
[0123] Next, an example of the process of formulating a bidding plan and a charging / discharging plan in day-ahead trading in the spot market and the demand adjustment market by the energy trading management system 1 according to this embodiment will be described with reference to FIG. 8 is a flowchart showing an example of the process of formulating a bidding plan and a charging / discharging plan in day-ahead trading in the spot market and the demand adjustment market (day-ahead commodity market: tertiary (2) electricity commodity) in the energy trading management system 1 according to this embodiment. Here, an example will be described in which two electricity markets, namely, day-ahead trading in the spot market and the demand adjustment market, are handled.
[0124] 8, the market bid processing unit 40 of the energy trading management device 10 sets the conditions for the market bid (step S201). The market bid management unit 41 of the market bid processing unit 40 sets various conditions required for day-ahead trading (tertiary (2) energy product) in the spot market and the demand adjustment market.
[0125] Next, the market bid management unit 41 acquires the contract result (step S202). The market bid management unit 41 acquires the current contract result stored in the contract information storage unit 123, for example.
[0126] Next, the market bid management unit 41 sets buying and selling constraints (step S203). The market bid management unit 41 sets buying and selling constraints, for example, based on the current contract result. For example, when a capacity market contract has been made and the activation probability of the capacity market is equal to or greater than a certain value (threshold value) (activation probability is high), the market bid management unit 41 sets buying and selling constraints such as restricting buying and selling during time periods when the activation probability of the capacity market is high.
[0127] Next, the market bid management unit 41 executes aggregation processing of adjustment power products (step S204). The market bid management unit 41 executes aggregation processing of power products in the demand adjustment market. The market bid management unit 41 calculates in advance the product that will maximize the expected profit for each time slot based on the forecast results for each product and each time slot, and aggregates which adjustment power product has the maximum expected profit for each time slot.
[0128] Next, the charge / discharge plan creating unit 132 calculates an initial charge / discharge plan (step S205). The charge / discharge plan creating unit 132 creates the initial charge / discharge plan based on the current contract result and the buying and selling constraints. Next, the charge / discharge plan creator 132 executes evaluation of the initial charge / discharge plan (step S206).
[0129] Next, the market bidding processing unit 40 considers spot bidding (step S207). The market bidding unit 42 corresponding to the spot market of the market bidding processing unit 40 formulates a bidding plan for the spot market.
[0130] Next, the market bidding processing unit 40 evaluates the spot bidding plan (step S208). The market bidding unit 42 corresponding to the spot market calculates the expected profit and loss using, for example, the method described in Figures 3 and 4, and evaluates the bidding plan for the spot market based on the expected profit and loss.
[0131] Next, the market bidding unit 42 corresponding to the spot market determines whether the bidding plan for the spot market needs to be improved (step S209). The market bidding unit 42 determines whether the improvement is necessary based on the evaluation result based on expected profit and loss. If the bidding plan for the spot market needs to be improved (step S209: YES), the market bidding unit 42 returns the process to step S207. If the bidding plan for the spot market does not need to be improved (step S209: NO), the market bidding unit 42 proceeds to step S210.
[0132] In step S210, the market bidding processing unit 40 considers adjustment reserve bidding so as to improve evaluation compared to the bidding plan for the spot market. The market bidding unit 42 corresponding to the day-ahead commodity market of the market bidding processing unit 40 formulates a bidding plan for the day-ahead commodity market (tertiary (2) electricity product).
[0133] Next, the market bidding processing unit 40 evaluates the plan for the day-ahead commodity market (step S211). The market bidding unit 42 corresponding to the day-ahead commodity market calculates the expected profit and loss using, for example, the method described in Fig. 5, and evaluates the bidding plan for the day-ahead commodity market based on the expected profit and loss.
[0134] Next, the market bidding unit 42 corresponding to the day-ahead commodity market determines whether the bidding plan for the day-ahead commodity market needs to be improved (step S212). The market bidding unit 42 determines whether improvement is necessary based on the evaluation results based on expected profits and losses. If the bidding plan for the day-ahead commodity market needs to be improved (step S212: YES), the market bidding unit 42 returns the process to step S210. If the bidding plan for the day-ahead commodity market does not need to be improved (step S212: NO), the market bidding unit 42 proceeds to step S213.
[0135] In step S213, the market bid processing unit 40 determines whether or not the spot market has been contracted. If the spot market has been contracted (step S213: YES), the market bid processing unit 40 proceeds to step S214. If the spot market has not been contracted (step S213: NO), the market bid processing unit 40 proceeds to step S215.
[0136] In step S214, the charge / discharge plan creation unit 132 calculates a final charge / discharge plan. The charge / discharge plan creation unit 132 discards the bidding plan of the spot market and calculates the final charge / discharge plan based on the current contract result.
[0137] Next, in step S215, the market bidding management unit 41 executes a process of expanding adjustment power products. The market bidding management unit 41 executes a process of expanding electricity products in the demand adjustment market. For example, in the case of the first frame: 30 kW on the tertiary (1), the second frame: 30 kW on the tertiary (1), the third frame: 50 kW on the secondary (1), and the fourth frame: no adjustment power provision, expansion is performed for each electricity product in the demand adjustment market as follows:
[0138] The market bidding management unit 41 develops the third (1) plan as follows: first frame: 30 kW, second frame: 30 kW, third frame: 0 kW, fourth frame: 0 kW. Furthermore, the market bidding management unit 41 develops the second (1) plan as follows: first frame: 0 kW, second frame: 0 kW, third frame: 50 kW, fourth frame: 0 kW. After the process of step S215, the market bid management unit 41 ends the process.
[0139] Next, the data utilization process of the energy trading management system 1 will be described with reference to FIG. FIG. 9 is a diagram illustrating an example of data utilization processing in the energy trading management system 1 according to this embodiment.
[0140] 9, first, the user terminal 30 transmits an output request for output information to the energy trading management apparatus 10 (step S301). In response to a user's operation of the input unit 32, the terminal control unit 35 of the user terminal 30 transmits the output request for output information such as various reports to the energy trading management apparatus 10 via the NW communication unit 31.
[0141] Next, the energy trading management device 10 generates output information based on the market information, the operation plan, and the actual value (step S302). In response to the output request, the data utilization unit 134 of the energy trading management device 10 generates output information such as various reports based on the market information (product information) stored in the market information storage unit 122, the charge / discharge plan stored in the charge / discharge plan storage unit 126, and the actual value stored in the actual value storage unit 127.
[0142] Next, the data utilization unit 134 transmits the output information to the user terminal 30 (step S303). The data utilization unit 134 transmits the generated output information such as various reports to the user terminal 30 via the NW communication unit 11.
[0143] Next, the terminal control unit 35 of the user terminal 30 displays the received output information such as various reports on the display unit 33 (step S304). The terminal control unit 35 displays, for example, the output information as shown in FIG. 10 as a report.
[0144] Fig. 10 is a diagram showing an example of the display of output information of the energy trading management system 1 according to this embodiment. The example shown in Fig. 10 shows an example in which the data utilization unit 134 has generated a display image G1 as a report, which includes graphs of the spot market price forecast and bidding plan (charging plan) and a graph of the SOC actual value of the power storage device 20.
[0145] In the above-described embodiment, the multiple electricity markets are a wholesale electricity trading market and a balancing market. However, the multiple electricity markets may be a wholesale electricity trading market or a balancing market and a capacity market where electricity capacity is traded.

[0188] Furthermore, in the above embodiment, the bidding planning unit (market bidding planning unit 422 and bidding planning unit 425) may create a bidding plan by mixing multiple electricity markets or multiple electricity products for the same time period. The bidding planning unit (market bidding planning unit 422 and bidding planning unit 425) may, for example, determine first bid schedule information for a first electricity product for a first time period and second bid schedule information for a second electricity product for a second time period based on a predicted transaction price of each product and requirement information (e.g., duration, etc.), so that the second time period included in the second bid schedule information overlaps at least partially with the first time period included in the first bid schedule information. Furthermore, the bidding planning unit (market bidding planning unit 422 and bidding planning unit 425) may determine first bid schedule information for the wholesale electricity trading market for the first time period and second bid schedule information for the balancing market for the second time period, so that the second time period included in the second bid schedule information overlaps at least partially with the first time period included in the first bid schedule information.
[0189] In the above embodiment, an example has been described in which the bid planning units (market bid planning unit 422 and bid planning unit 425) are provided in each market bid unit 42 (42a), but this is not limiting. The functions of each bid planning unit (market bid planning unit 422 and bid planning unit 425) may be combined into one, and provided in the market bid processing unit 40 (40a) instead of each market bid unit 42 (42a).
[0190] Each component of the energy trading management system 1 (1a) described above has an internal computer system. A program for realizing the function of each component of the energy trading management system 1 (1a) described above may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform processing in each component of the energy trading management system 1 (1a) described above.

The "computer system" referred to here includes an OS and hardware such as peripheral devices.
[0191] Furthermore, a "computer system" may include multiple computer devices connected via a network, including communication lines such as the Internet, WAN, LAN, and dedicated lines. Furthermore, a "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as hard disks built into a computer system. Thus, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM.
[0192] The recording medium also includes internal or external recording media accessible from a distribution server for distributing the program. The program may be divided into multiple parts, downloaded at different times, and then combined by each component of the energy trading management system 1 (1a), or each divided program may be distributed by a different distribution server. Furthermore, the term "computer-readable recording medium" also includes a medium that stores a program for a certain period of time, such as volatile memory (RAM) within a computer system that acts as a server or client when a program is transmitted over a network. The program may also be a medium for implementing part of the above-described functions. Furthermore, the program may be a so-called differential file (differential program) that can realize the above-described functions in combination with a program already stored in the computer system.
