The present invention relates to a power trading support device, a power trading support method, and a program.

In recent years, Balancing Groups (hereinafter also referred to as "BGs") have been used as a group of businesses to settle imbalances (differences between plans and actual results) in electricity trading. BG includes power generation BG by power generation companies and demand BG by consumers. In the following, when it is simply referred to as "BG", it refers to the power generation BG.

The BG operates, for example, a plurality of renewable energy (renewable energy) power sources (for example, solar power generators, wind power generators, etc., hereinafter also referred to as power resources or resources). Although the amount of power generated by each renewable energy power source fluctuates, the BG works to simultaneously generate the same amount of electricity as planned, thereby reducing the risk of imbalance.

Further, the combination of resources associated with a BG can be changed. The aggregator operator aims to simultaneously achieve the same planned value for each BG while managing multiple resources, and to suppress a decrease in revenue due to imbalance settlement. Therefore, the operator needs to determine an appropriate combination of BG and resources at each predetermined timing.

The UI function 53 is a function that supports an aggregator operator in determining an appropriate combination of BG and electric power resources, and includes an attribute DB (Data Base) 531, a power generation prediction DB 532, an acquisition unit 533, and a processing unit 534. and.

In the attribute DB 531, one or more BGs are associated with each of a plurality of power areas, and one or more power plants are associated with each BG. Here, FIG. 2 is a diagram schematically showing the contents of the attribute DB 531 of the embodiment.

As shown in FIG. 2, the attribute DB 531 has a five-level hierarchical structure. First, at the first level, there is an aggregator. One or more second-tier power areas are associated with the aggregator. One or more third layer BGs are associated with each power area.

Furthermore, one or more fourth-tier power plants are associated with each BG. In that case, the power plant can be assigned to any BG within the power area. A plurality of BGs can be set within the power area, and management can be performed on a BG basis. One or more resources of the fifth layer are associated with each power plant.

Further, in the attribute DB 531, design values, locations, etc. on the system of each resource are set. In addition, resources are managed on a power plant basis. By managing a plurality of resources on a power plant basis, it is possible to create an operation plan for the storage battery 9 limited to that power plant. For example, it is possible to plan and control the charging of the storage battery 9 only based on the amount of renewable energy generated within the power plant, or to plan and control the discharge of the storage battery 9 within the authorized output of the entire power plant.

Further, even resources that are geographically distant may be allowed to be virtually associated with one power plant. Normally, multiple resources that are geographically close are bundled into one virtual power plant, but in this embodiment, by using a cloud environment, it is possible to associate distant resources as belonging to the same power plant. It is possible. Although such an operation is not actually possible under the current system, if it becomes possible under the system, it would be desirable to associate distant resources (for example, if the so-called smoothing effect of power generation is more effective). This is a useful feature if there is a possibility.

In this way, all resources will be managed by one aggregator. Recording and prediction of the actual power generation amount is performed on a resource-by-resource basis, and the actual power generation amount and predicted value of the resources under the specified power plant, BG, and power area are integrated and visualized for the user. (Details will be described later).

Returning to FIG. 1, the power generation amount prediction DB 532 is data similar to the prediction data 511, and stores the power generation amount prediction results for each resource.

The acquisition unit 533 acquires various input data such as search conditions from the user terminal 3.

The processing unit 534 executes various information processing. For example, in the registration mode, the processing unit 534 causes the display unit 31 of the user terminal 3 to display power plants that can be associated with the BG, and registers the combination of the BG and the power plant selected by the operator in the attribute DB 531.

Furthermore, in the predicted output mode, the processing unit 534 causes the display unit 31 of the user terminal 3 to selectably display each item of power area, BG, and power plant, and the items are associated with the items selected by the operator. Accumulate and display the power generation amount prediction results for each power resource belonging to the power plant. This will be explained with reference to FIG.

FIG. 3 is a diagram showing an example of a power generation amount prediction output screen according to the embodiment. A search condition selection screen is displayed in area R1. In area R2, a BG list is displayed as a search condition. In area R3, a list of power plants is displayed as a search condition.

Area R4 contains the total value of the predicted power generation results and the total value of the actual power generation amount for each power resource belonging to the power plant associated with the item (power area, BG, power plant) selected by the operator. is displayed. The bar graph shows the total value of the actual power generation amount. Further, graphs P1 to P5 show the prediction results of five different same-day prediction models for predicting the amount of power generation. Further, graphs Q1 to Q5 show respective prediction results using five different day-ahead prediction models that predict the amount of power generation.

In the case of the renewable energy power source 6, the amount of power generated depends on the weather, etc., so the predicted value has uncertainty. Therefore, on this screen, a plurality of prediction results obtained by various prediction methods (here, five prediction methods) are represented by lines based on weather forecasts and the like.

For example, when the operator selects "Entire power area" in area R2, the total value of the power generation amount prediction results and the power generation amount actual value of the resources associated with all the power areas, that is, all the resources. is displayed in area R4.

Further, for example, when the operator selects "area A" in area R2, the total value of the power generation amount prediction results and the total value of the power generation amount actual value of the resources associated with power area A are displayed in area R4.

Further, for example, when the operator selects "power plant A" in area R3, the total value of the power generation amount prediction results and the total value of the power generation amount actual value of the resources associated with power plant A is displayed in area R4. .

Although not shown directly in Figure 3, individual BGs are displayed in a selectable manner, and the total value of the power generation amount prediction results and the total power generation amount actual value of the resources associated with the selected BG is displayed. may be displayed in area R4. In that case, for example, when any of the power areas in region R2 is selected, the BGs under that power area may be displayed and selectable.

The operator looks at a screen like this and uses the actual power generation amount and multiple predicted future values to determine future transaction bid amounts in the electricity market, taking into account the range of uncertainty regarding future power generation amount. be able to make decisions. In addition, although the prediction results of both the same-day prediction model and the previous day's prediction model are displayed, generally speaking, the shorter the prediction lead time, the better the prediction accuracy. The operator can intuitively understand whether the value has increased or decreased.

In addition, in the registration mode, when displaying power plants that can be associated with a BG on the display unit 31 of the user terminal 3, the processing unit 534 displays, for each BG, power resources existing in the power area including the location of the BG. It is also possible to display only the

Furthermore, in the registration mode, the processing unit 534 causes the display unit 31 of the user terminal 3 to display power resources that can be associated with the power plant, and registers the combination of power plant and power resource selected by the operator in the attribute DB 531. You may also do so.

Further, in the predicted output mode, the processing unit 534 may display selection buttons for each item of power area, BG, and power plant side by side on one screen of the display unit 31 of the user terminal 3.

Returning to FIG. 1, the resource cooperation I/F 54 is a function of an interface that cooperates with each resource. For example:
(1) Control command function for resources (2) CSV (Comma Separated Value) file upload function (3) Data registration API (Application Program Interface) function (4) PV monitoring function (5) Other power sources not shown Cooperation function with monitoring system (6) Storage battery cooperation function (7) OpenADR (automatic demand response) function (8) Individual resource cooperation function

Further, although not shown in FIG. 1, there may be a system or service function between the resource cooperation I/F 54 and the resource. For example, a negawatt system may be provided between the resource cooperation I/F 54 and the private power generator 8. Further, for example, a storage battery VPP (Virtual Power Plant) service function may be provided between the resource cooperation I/F 54 and the storage battery 9.

In this way, the resource cooperation I/F 54 enables cooperation with multiple types of resources.

Other examples of display screens will be described below with reference to FIGS. 4 to 7. FIG. 4 is a diagram showing an example of a power price prediction output screen according to the embodiment. By looking at this screen, the user can check price prediction information on the electricity market and the like. A search condition selection screen is displayed in area R11.

In area R12, price prediction information and price performance information are displayed in graphs for the designated area or nationwide area. Graph SR shows spot market price performance. Graph SP shows spot market price prediction. Graph TR shows the pre-hour market price performance. Graph TP shows an hourly market price prediction. In area R13, price prediction information and price performance information are displayed in numerical values.

In the electricity market, a spot market and an hourly market have been established, and operators need to predict prices in multiple markets, decide on the amount of bids to be placed in the market and the bid price, and place a bid. By looking at the screen shown in FIG. 4, the operator can grasp the performance and prices of multiple markets at the same time, and therefore can accurately and quickly make decisions regarding the amount of bids and bid prices for the market.

FIG. 5 is a diagram showing an example of an operation plan screen for the storage battery 9 according to the embodiment. A search condition selection screen is displayed in area R21. A storage battery list screen is displayed in area R22.

A charging/discharging plan for the storage battery 9 is displayed in the area R23. Graph G1 shows SoC (State of Charge). Graph G2 shows the discharge plan. Graph G3 shows a charging plan.

In the area R24, the imbalance amount (bar graph) and the system price (line graph) are displayed. In the area R25, numerical values of the charging amount plan and the actual charging amount are displayed.

Storage battery detailed information is displayed in area R26. For example, the BG name, power plant name, storage battery name, storage battery operation mode, etc. are displayed.

The operator can display the operation plan of the storage battery 9 as shown in FIG. 5 according to the constraints of the operation plan of the storage battery 9, and check the actual charging/discharging status and SoC of the storage battery 9.

FIG. 6 is a diagram illustrating an example of a screen showing a breakdown of power for each resource according to the embodiment. A search condition selection screen is displayed in area R31. A BG list screen is displayed in area R32.

In the area R33, a breakdown of power for each resource (for example, biomass, hydropower, wind power, PV, storage battery, market procurement, etc.) is displayed.

In the region R34, the imbalance amount (bar graph) and the system price (line graph) are displayed.
In area R35, numerical values of the plan, actual results, and imbalance are displayed.

In area R36, a list of power plants and their operating status are displayed.

By looking at a screen like the one shown in FIG. 6, the operator can easily grasp the breakdown of each power resource and utilize it for each task.

In addition, in the region R33 in FIG. 6, the past part and the future part may be displayed so as to be distinguishable at a glance by displaying the part after the current time in a lighter color.

FIG. 7 is a diagram illustrating an example of a screen showing a breakdown of electricity wholesalers according to the embodiment. This screen is used by the operator to determine the amount of bids to be placed in the market and to actually bid in the market. By operating the "Post-bidding plan" operation button in the upper left, the power generation source and type of wholesaler (bar graph) will be displayed in the event that the amount of power generated for the bid is contracted.

More specifically, for example, the processing unit 534 causes the display unit 41 to display an operation button for “post-bidding plan” in the electric power supplier breakdown display mode, and when the operation button is operated by the operator, The amount of electricity for each wholesaler is displayed in a different color, pattern, etc., in the case that the amount of electricity for which the electricity sale has already been bid is contracted, so that the amount of electricity can be identified by the operator.

By looking at a screen like the one shown in FIG. 7, the operator can easily grasp the amount of electricity for each electricity wholesaler, which can be utilized in various operations. For example, an operator creates a power generation plan based on the predicted power generation amount on the day before the transaction, and when it becomes clear on the day of the transaction that the power generation amount will be lower than the previous day's prediction, the operator performs an operation to change the power sales amount plan. Here, by displaying a display that makes it easy to distinguish between selling electricity to JEPX as a wholesaler and selling electricity to a partner, the operator can maintain selling electricity to a partner if the amount of power generation is lower than the previous plan. This makes it easier to adjust the amount of electricity sold to JEPX. It is assumed that in bilateral transactions, there is a penalty if the amount of electricity sold is not achieved as specified in the contract, whereas in market transactions, the revenue from selling electricity only decreases in accordance with the decrease in the amount of electricity sold, and operators mainly It is considered that only market transactions are adjusted. Therefore, by facilitating such operations, the burden on the operator can be reduced.

Next, the process for displaying the screen in FIG. 3 will be described with reference to FIG. 8. FIG. 8 is a flowchart showing processing by the UI function 53 of the embodiment.

First, in step S1, the acquisition unit 533 acquires input attribute information (information on combinations of items in FIG. 2) from the user terminal 3.

Next, in step S2, the acquisition unit 533 registers the attribute information acquired in step S1 in the attribute DB 531.

Next, in step S3, the input search conditions (for example, "Area A", "BG1", "Power Plant A", etc.) are acquired from the user terminal 3.

Next, in step S4, the processing unit 534 identifies a resource (a resource under the search condition) corresponding to the search condition input in step S3.

Next, in step S5, the processing unit 534 integrates the power generation amount prediction results of the resources identified in step S4.

Next, in step S6, the processing unit 534 displays the obtained information processed in step S5 on the display unit 31 of the user terminal 3 (region R4 in FIG. 3).

Next, in step S7, the processing unit 534 determines whether new search conditions (for example, "area A", "BG1", "power plant A", etc.) have been acquired from the user terminal 3, If Yes, the process returns to step S4, and if No, the process proceeds to step S8. That is, when the search conditions are changed, the screen display in area R4 in FIG. 3 is changed to display a graph according to the latest search conditions.

In step S8, the processing unit 534 determines whether or not there is an operation to end the display on the user terminal 3. If Yes, the process proceeds to step S9 to end the display, and if No, the process returns to step S7.

As described above, according to the UI function 53 of the cloud environment 5 of this embodiment, as shown in FIG. It is possible to support determination of an appropriate combination of BG and resources.

Moreover, if only the resources existing in the power area including the location of the BG are displayed for each BG in the registration mode, operability by the operator can be further improved.

In addition, in registration mode, if it is possible to virtually associate resources with one power plant even if they are geographically distant, resource operation planning can be done as if the resources were handled within one power plant. and can be controlled.

Further, in the predicted output mode, if the selection buttons for each item of power area, BG, and power plant are displayed side by side on one screen, operability for the operator can be further improved.

Further, by displaying the screens shown in FIGS. 4 to 7, it is possible to support the operator's work.

The program executed by the UI function 53 of this embodiment is an installable or executable file that can be stored on a computer such as a CD-ROM, flexible disk (FD), CD-R, or DVD (Digital Versatile Disk). It may also be provided recorded on a readable recording medium.
