Description

[Technical Field]

[0001] The present disclosure relates to a data management device, a data management system, a data display method, and a program for displaying information related to an electricity market. [Background technology]

[0002] In recent years, electricity markets have become increasingly popular, including the Japan Electric Power Exchange (JEPX). Various pieces of information must be taken into consideration when bidding in the electricity market. Examples of information related to the electricity market include imbalance charges and imbalance amounts, which are important indicators used by power generators and retailers when bidding in the electricity market.

[0003] Conventionally, as described in Patent Document 1, for example, imbalance charges and imbalance amounts have been calculated for each electricity transmission and distribution company, and the calculation results have also been managed for each electricity transmission and distribution company. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-299180 Summary of the Invention [Problem to be solved by the invention]

[0005] However, it is expected that imbalance charges and imbalance amounts managed by multiple transmission and distribution companies will also be considered as a whole, rather than just on a transmission and distribution company basis, and it is desirable that information managed by multiple transmission and distribution companies be provided in one place.

[0006] The present disclosure has been made in view of the above, and aims to provide a data management device that can collectively provide information on the electricity market relating to a plurality of electricity transmission and distribution companies. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems and achieve the objectives, the data management device disclosed herein includes an acquisition unit that acquires electricity market related information, which is information about the electricity market for each time period corresponding to each of a plurality of transmission and distribution areas, and a data display unit that displays the electricity market related information for the plurality of transmission and distribution areas as a graph in a single graph area with the horizontal axis representing the time period. The electricity market-related information includes the surplus imbalance charge unit price, which is the imbalance charge unit price when there is an electricity surplus, the shortage imbalance charge unit price, which is the imbalance charge unit price when there is an electricity shortage, and the imbalance amount. . [Effects of the Invention]

[0008] According to the present disclosure, it is possible to provide information on the electricity market relating to a plurality of electricity transmission and distribution companies in a consolidated manner. [Brief explanation of the drawings]

[0010] A data management device, a data management system, a data display method, and a program according to embodiments will be described in detail below with reference to the accompanying drawings.

[0011] Embodiment FIG. 1 illustrates an example of the configuration of a data management system including a data management device according to an embodiment. The data management system 100 includes a data management device 1 and a bidding support device 3. The data management device 1 acquires information managed by the data providing devices 2-1 to 2-N from the data providing devices 2-1 to 2-N, and uses the acquired information to collectively display information related to the electricity market (electricity market-related information). The information related to the electricity market includes, for example, imbalance charge unit prices (surplus and shortage) and imbalance amounts. The data providing devices 2-1 to 2-N are each managed by a different electricity transmission and distribution business operator and correspond to a different electricity transmission and distribution area. For example, N is 9, and the data providing devices 2-1 to 2-N correspond to the electricity transmission and distribution areas of Hokkaido, Tohoku, Tokyo, Chubu, Hokuriku, Kansai, Chugoku, Shikoku, and Kyushu, respectively. However, the number of N and the corresponding electricity transmission and distribution areas are not limited to this example. Hereinafter, when the data providing devices 2-1 to 2-N are referred to without being individually distinguished, they will be referred to as data providing device 2. The data providing devices 2-1 to 2-N may be included in the data management system 100.

[0012] Each data providing device 2 manages various types of information in the corresponding power transmission and distribution area, and transmits information used to calculate information related to the electricity market to the data management device 1. Information used to calculate information related to the electricity market includes, for example, data indicating the amount of power that can be adjusted, trading information in the spot market, trading information in the time-ahead market, information on the actual implementation of power usage restrictions, information on the actual implementation of planned power outages, information related to blackouts, a calculation index used to calculate correction charges, information on the implementation and marginal kWh price of power source I' (supply capacity secured in addition to the power source of the power transmission and distribution company), information on the implementation of renewable energy (renewable energy) output suppression, and information on the implementation of output suppression of power source III (such as a power source that cannot be adjusted online by the power transmission and distribution company).

[0013] As shown in FIG. 1, the data management device 1 includes a data acquisition unit 11, a display data calculation unit 12, an input reception unit 13, an information transmission unit 14, a data storage unit 15, a display control unit 16, and a data display unit 17.

[0014] The data acquiring unit 11 receives the above-mentioned information from each data providing device 2 and outputs the received information to the display data calculating unit 12. The display data calculating unit 12 uses the information received from the data acquiring unit 11 to calculate information about the electricity market as display data and stores the calculated display data in the data storage unit 15. The display data calculating unit 12 may also store the information used to calculate the display data, i.e., the information transmitted from the data providing device 2, in the data storage unit 15. As described above, the information about the electricity market is, for example, the imbalance charge unit price (surplus and shortage) and the imbalance amount for each time period. Below, an example will be described in which the information about the electricity market includes three items: the surplus imbalance charge unit price, the shortage imbalance charge unit price, and the imbalance amount; however, the information about the electricity market is not limited to these. The surplus imbalance charge unit price is the imbalance charge unit price when there is a power surplus, and the shortage imbalance charge unit price is the imbalance charge unit price when there is a power shortage.

[0015] In this embodiment, the display data calculation unit 12 calculates the surplus imbalance charge unit price, shortage imbalance charge unit price, and imbalance amount for N power transmission and distribution areas using information acquired from, i.e., information received from, each data providing device 2. The surplus imbalance charge unit price and shortage imbalance charge unit price are determined, for example, according to the transaction price (unit price) in the spot market and the transaction price (unit price) in the hourly market, as well as various adjustment terms and calculation indexes. The calculation methods for the surplus imbalance charge unit price, shortage imbalance charge unit price, and imbalance amount are the same as the calculation methods used by each power transmission and distribution utility, and therefore details are omitted. This makes it possible to efficiently calculate the surplus imbalance charge unit price, shortage imbalance charge unit price, and imbalance amount for each power transmission and distribution area using a unified standard.

[0016] Note that the following describes an example in which the display data calculation unit 12 calculates the surplus imbalance charge unit price, the shortage imbalance charge unit price, and the imbalance amount. However, this is not limiting. Each of the data providing devices 2 may calculate the surplus imbalance charge unit price, the shortage imbalance charge unit price, and the imbalance amount, and transmit the surplus imbalance charge unit price, the shortage imbalance charge unit price, and the imbalance amount to the data management device 1. In this case, the data management device 1 does not need to include the display data calculation unit 12, and the data acquisition unit 11 stores the surplus imbalance charge unit price, the shortage imbalance charge unit price, and the imbalance amount received from each data providing device 2 in the data storage unit 15. In other words, the data management device 1 may only include an acquisition unit that acquires electricity market-related information, which is information related to the electricity market for each time period corresponding to each of the multiple transmission and distribution areas. The acquisition unit may include the data acquisition unit 11 and the display data calculation unit 12, as shown in FIG. 1, or may include only the data acquisition unit 11.

[0017] The input receiving unit 13 receives input from the user. For example, the input receiving unit 13 receives input of selection results such as a display method and a range of data to be displayed when displaying display data (described later), and outputs the received selection results to the display control unit 16.

[0018] The information transmission unit 14 transmits the display data stored in the data storage unit 15, i.e., data on the three elements of the surplus imbalance fee unit price, the shortage imbalance fee unit price, and the imbalance amount, to the bid support device 3. Note that, here, an example will be described in which the data management device 1 cooperates with the bid support device 3 by transmitting information to the bid support device 3, but this is not limiting, and the data management device 1 does not need to transmit information to the bid support device 3. If the data management device 1 does not transmit information to the bid support device 3, the data management device 1 does not need to include the information transmission unit 14.

[0019] The display control unit 16 reads out the display data stored in the data storage unit 15, generates display screen data showing a display screen that displays the read display data, and outputs the display screen data to the data display unit 17, thereby causing the data display unit 17 to display the display data. The display control unit 16 determines a display method for the display data according to the selection result received by the input receiving unit 13, and generates the display screen data based on the determined display method. Specifically, the display control unit 16 generates the display screen data so that data for N transmission and distribution areas (hereinafter also referred to as areas) are collectively displayed as a graph for at least one element in the display data, and generates the display screen data so that data corresponding to the area selected according to the selection result received by the input receiving unit 13 is highlighted.

[0020] The data display unit 17 displays display data under the control of the display control unit 16. In detail, the data display unit 17 displays display screen data generated by the display control unit 16. For example, the data display unit 17 displays electricity market-related information for multiple transmission and distribution areas as a graph in one graph area with the horizontal axis representing time periods. The data display unit 17 also highlights a graph showing electricity market-related information corresponding to a selected area, which is a transmission and distribution area selected by a user from the multiple transmission and distribution areas.

[0021] Next, a method for displaying display data according to this embodiment will be described. As described above, in this embodiment, data for N areas is displayed together for at least one element in the display data. This allows a user to check data for multiple areas at once. However, when displaying data for N areas for at least one element in the display data together, if the areas are simply displayed in different colors, it may be difficult for the user to visually identify which data corresponds to the area of ​​interest if there are sections where the data values ​​are similar or identical. For example, if a user wants to simultaneously check three elements, the surplus imbalance charge unit price, the shortage imbalance charge unit price, and the imbalance amount, and if these are all displayed as a graph, the surplus imbalance charge unit price, the shortage imbalance charge unit price, and other elements may have sections where the data values ​​are similar or identical, resulting in overlapping lines. In particular, if all nine transmission and distribution areas across Japan are targeted, i.e., if N is 9, and all elements are displayed as a line graph, for example, 2 (elements) × 9 (areas) lines are displayed, making it difficult to determine which line corresponds to which area.

[0022] For this reason, in this embodiment, as will be described later, the graphs corresponding to each area and each element are displayed, for example, in a single color, and when a selection result indicating the information that the user is interested in is received from the user, the portion corresponding to the selection result is highlighted, allowing the user to simultaneously check the information of all areas and to easily view the selected information.

[0023] Fig. 2 is a flowchart showing an example of a display processing procedure for display data according to the present embodiment. The processing shown in Fig. 2 may be started, for example, when a user starts application software that displays the display data, or when the data management device 1 is started, but the timing at which the processing shown in Fig. 2 is started is not limited to these examples.

[0024] As shown in FIG. 2, the data management device 1 first displays data (step S1). Specifically, the display control unit 16 reads display data stored in the data storage unit 15, generates initial screen data corresponding to an initial screen using the read display data, and displays the generated initial screen data on the data display unit 17. The initial screen is a screen displayed in an initial state when the user has not yet input a selection result, and the range of display data displayed on the initial screen is set in advance. The range of display data displayed on the initial screen, the elements displayed on the initial screen, and the like are stored in the data storage unit 15 as setting information. For example, the setting information may be changeable by the user. For example, the display control unit 16 displays a screen for accepting setting information on the data display unit 17, and the input accepting unit 13 accepts input from the user and notifies the display control unit 16 of the accepted content. The display control unit 16 updates the setting information in the data storage unit 15 based on the content notified by the input accepting unit 13.

[0025] FIG. 3 is a diagram showing an example of an initial screen of this embodiment. In the example shown in FIG. 3, three elements, namely, an excess imbalance charge unit price, a shortage imbalance charge unit price, and an imbalance amount, are displayed as graphs. The initial screen shown in FIG. 3 displays a selection box 201 for selecting an area, a graph display area 202 which is a graph area where a graph is displayed, and a numeric display area 203 where the numerical values ​​of the elements are displayed. The selection box 201 is used by the user to select an area, and no area is selected in the initial screen shown in FIG. 3. The graph display area 202 is an area where display data for each area is displayed as a graph. The horizontal axis of the graph displayed in the graph display area 202 indicates time (time, time zone), and the vertical axis indicates the value of each item in the display data. The numeric display area 203 is an area where the value of each element at a position on the horizontal axis selected by the user in the graph display area 202 is displayed.

[0026] Selection bar 204 displayed in graph display area 202 is a bar for selecting the value on the horizontal axis of the value displayed in numeric display area 203, i.e., time. Selection bar 204 can be moved horizontally, and the time corresponding to the value displayed in numeric display area 203 changes when the user moves the position of selection bar 204. Also provided in graph display area 202 is a time display range change button 205, and clicking on the triangular portion displayed as time display range change button 205 changes the time display range of the graph in three-hour increments. Although the symbol is omitted, the triangle to the left of 0:00 is also a time display range change button 205. Clicking the time display range change button 205 to the left of 0:00 changes the displayed time range from three hours before the current range (if it is 0:00 on the current day, it will start at 21:00 the previous day) to a 24-hour display (if it is 21:00 the previous day, it will display up to 21:00 on the current day), and clicking the time display range change button 205 to the right of 24:00 changes the displayed time range from three hours after the current range (if it is 0:00 the previous day, it will start at 3:00 the previous day) to a 24-hour display (if it is 3:00 the previous day, it will display up to 3:00 on the current day).

[0027] In the example shown in FIG. 3 , the graph display area 202 displays the surplus imbalance charge unit price and the shortage imbalance charge unit price as a solid line graph 206 and a dotted line graph 207, respectively. In FIG. 3 , the surplus imbalance charge unit price and the shortage imbalance charge unit price for each of the nine areas are all displayed in the same color, i.e., a single color. In the example shown in FIG. 3 , a total of 18 lines are actually displayed as lines, but the lines overlap because there are time periods when the data between areas is the same or the data for the surplus imbalance charge unit price and the shortage imbalance charge unit price are the same. The surplus imbalance charge unit price and the shortage imbalance charge unit price are often nearly similar, so they can overlap like this. It is also meaningful to check whether the surplus imbalance charge unit price and the shortage imbalance charge unit price are nearly similar, and it is also meaningful to check the difference if there is a difference. Therefore, it is desirable to display the surplus imbalance charge unit price and the shortage imbalance charge unit price simultaneously. In the example shown in Fig. 3, the amount of imbalance is shown as a bar (bar graph). In the example shown in Fig. 3, the amount of imbalance is displayed as a graph with only the data corresponding to one selected area.

[0028] In this way, the data display unit 17 may display the surplus imbalance charge unit prices for the multiple power transmission and distribution areas as a line graph in the graph display area 202, display the shortage imbalance charge unit prices for the multiple power transmission and distribution areas as a line graph with a line type different from the line graph of the surplus imbalance charge unit prices in the graph display area 202, and highlight the line graphs of the surplus imbalance charge unit prices and shortage imbalance charge unit prices corresponding to the selected area. Furthermore, the data display unit 17 may display the imbalance amount corresponding to the selected area as a bar graph in the graph display area 202.

[0029] In the example shown in FIG. 3, the area in which the imbalance amount is displayed on the initial screen is assumed to be determined by, for example, setting information, and the imbalance amount is also displayed on the initial screen. However, the imbalance amount may not be displayed on the initial screen, and may be displayed after an area is selected. Also, in the example shown in FIG. 3, the surplus imbalance charge unit price, the shortage imbalance charge unit price, and the imbalance amount are respectively shown as a solid line graph, a dotted line graph, and a bar graph, but the graph used to display each element is not limited to this example. For example, the imbalance amount for the entire area may be displayed as a dashed-dotted line graph. Also, the user may be able to set, as setting information, which graph to display each element.

[0030] In the example shown in FIG. 3, the data for each element of the display data is data every 30 minutes, and when a time is selected with the selection bar 204, the time is selected in 30-minute increments. Note that the unit time of the data is just an example, and it may be other than 30 minutes. In the example shown in FIG. 3, the selection bar 204 is displayed at a position corresponding to 12:00-12:30, which is the initial position, so the values ​​of each element in each area corresponding to 12:00-12:30 are displayed in the numeric display area 203. Note that in the example shown in FIG. 3, since no area is selected, all the numeric values ​​displayed in the numeric display area 203 are displayed in the same manner, and no numeric values ​​are highlighted.

[0031] Returning to the explanation of FIG. 2, the data management device 1 determines whether an area selection result has been input (step S2). More specifically, the display control unit 16 determines whether an area has been notified as a selection result from the input receiving unit 13. The user can select an area in a menu format in the selection box 201 shown in FIG. 3. When an area is selected in the selection box 201, the input receiving unit 13 notifies the display control unit 16 of the selected area as a selection result. Note that the method of receiving the selection result using the selection box 201 shown in FIG. 3 is just one example, and the method of receiving the area selection result is not limited to the example shown in FIG. 3. The selection result may be input by the user directly inputting the area name, or a list of area names may be displayed together with corresponding radio buttons or check boxes, and the area may be selected using these buttons, or the input of the selection result may be received in a manner other than these.

[0032] If an area selection result is input (Yes in step S2), the data management device 1 highlights the graph of the selected area (step S3). In detail, the display control unit 16 generates screen data in which the graph corresponding to the selected area notified by the input receiving unit 13 is highlighted, and causes the generated screen data to be displayed on the data display unit 17.

[0033] FIG. 4 is a diagram showing an example of a display screen according to the present embodiment after an area has been selected. In the example shown in FIG. 4, area C (area C) is selected in selection box 201, and the surplus imbalance charge unit price and shortage imbalance charge unit price corresponding to C are displayed as graph 209, a solid line graph, and graph 210, a dotted line graph, respectively. As can be seen from FIG. 4, graphs 209 and 210 are highlighted in a color different from the lines corresponding to other areas. This makes it easier for the user to check the data for the selected area even if it overlaps with the graphs for other areas. Note that while FIG. 4 shows highlighting by changing the color, other methods of highlighting may also be used, such as changing the line thickness or changing the marks of data points.

[0034] 4, in the numeric display region 203, the numeric value corresponding to the selected area is highlighted by being displayed in bolder than the other numeric values, as shown in the portion 211 showing the numeric value corresponding to the selected area. Note that in FIG. 4, the numeric value is highlighted by being displayed in bold, but this is not limiting, and the numeric value may also be highlighted by changing the color or font of the numeric value.

[0035] Another possible method for displaying data in a graph is to use a tooltip to display numerical values ​​corresponding to a graph selected by the user in the graph display area 202 near the selected graph. However, using a tooltip hides the graph when the numerical values ​​are displayed, making it difficult to see both the graph and the numerical values. In this embodiment, as shown in FIGS. 3 and 4 , the user specifies a position in the horizontal axis direction using a selection bar 204, and a numerical value display area 203 is provided below the graph display area 202. The numerical values ​​are displayed in the numerical value display area 203. This allows the user to see both the graph and the numerical values. Furthermore, as shown in FIG. 4 , the numerical values ​​of the selected area are highlighted and the numerical values ​​of other areas are also displayed, allowing the user to identify and check the numerical values ​​of the selected area in detail while comparing them with the numerical values ​​of other areas. In the example shown in FIGS. 3 and 4 , the numerical value display area 203 is displayed below the graph display area 202. However, this is not a limitation; the numerical value display area 203 may be located above or to the side of the graph display area 202, and the location of the numerical value display area 203 is not limited to the example shown in FIGS. 3 and 4 .

[0036] Returning to the explanation of FIG. 2, the data management device 1 next determines whether an instruction to move the horizontal axis selection bar 204 has been input (step S4). More specifically, the display control unit 16 determines whether the input of an instruction to move the horizontal axis selection bar 204 has been notified by the input receiving unit 13. As described above, when the user wishes to change the time (hour) at which the numerical values ​​are displayed, the user moves the selection bar 204 shown in FIGS. 3 and 4 horizontally to instruct a change of the time at which the numerical values ​​are displayed. When the input receiving unit 13 detects that the position of the selection bar 204 has moved, it notifies the display control unit 16 that an instruction to move the horizontal axis selection bar 204 has been input. At this time, the input receiving unit 13 also notifies the display control unit 16 of information indicating the position of the selection bar 204 after it has been moved.

[0037] If an instruction to move the horizontal axis selection bar 204 is input (Yes in step S4), the data management device 1 displays the data for the specified time in another area of ​​the same screen (step S5). In detail, the display control unit 16 calculates the specified time based on information indicating the position after the selection bar 204 is moved, generates screen data to display the data for the specified time as a numerical value in the numerical value display area 203, which is another area of ​​the same screen as the graph display area 202, and causes the data display unit 17 to display the generated screen data. That is, the data display unit 17 displays the numerical values ​​of the electricity market-related information corresponding to the time period selected by the user in a position different from the graph area. Note that if an area has already been selected, the display control unit 16 generates screen data to highlight the numerical values ​​corresponding to the selected area. As a result, the data display unit 17 highlights the numerical values ​​of the electricity market-related information corresponding to the selected area.

[0038] Next, the data management device 1 determines whether an instruction to change the display range of the horizontal axis has been input (step S6). Specifically, the display control unit 16 determines whether the input receiving unit 13 has notified the user that an instruction to change the display range of the horizontal axis has been input. As described above, when the user wants to change the display range of the horizontal axis, the user instructs the user to change the display range by pressing (clicking) one of the two time display range change buttons 205 shown in FIGS. 3 and 4. When the input receiving unit 13 detects that one of the two time display range change buttons 205 has been pressed, the input receiving unit 13 notifies the display control unit 16 that an instruction to change the display range of the horizontal axis has been input. At this time, the input receiving unit 13 also notifies the display control unit 16 of information indicating which of the two time display range change buttons 205 has been pressed.

[0039] If an instruction to change the display range of the horizontal axis is input (Yes in step S6), the data management device 1 changes the display range of the horizontal axis (step S7). Specifically, based on information indicating which of the two time display range change buttons 205 was pressed, the display control unit 16 generates screen data in which the display range of the horizontal axis is changed by a predetermined time in the direction corresponding to the pressed time display range change button 205, and causes the data display unit 17 to display the generated screen data. That is, the data display unit 17 displays the time display range change button 205 for changing the display range of the horizontal axis, and when the time display range change button 205 is pressed, the display range of the horizontal axis is changed by the predetermined time. The predetermined time is, for example, three hours corresponding to one scale in FIGS. 3 and 4, but is not limited to this and may be one hour. The predetermined time is not limited to these examples. 4, the display range is from 0:00 to 24:00, but when the time display range change button 205 on the left is pressed in this state, the display range is changed to from 21:00 of the previous day to 21:00 of the current day. Note that when the time display range change button 205 is pressed consecutively, steps S6 and S7 are performed each time the button is pressed.

[0040] Next, the data management device 1 determines whether an input to end the display has been received (step S8). Specifically, the display control unit 16 determines whether a notification that an input to end the display has been received has been received from the input receiving unit 13. For example, a display end button (not shown) is displayed on the screen, and the user may instruct the display to end by pressing the display end button, or may input an instruction to end the display using a keyboard or the like. When the input receiving unit 13 receives an input to end the display from the user, it notifies the display control unit 16 that an input to end the display has been received. Furthermore, in the case where the display starts upon startup of the data management device 1, the input receiving unit 13 may notify the display control unit 16 that an input to end the display has been received when it receives an input such as logging out or shutting down the data management device 1.

[0041] If an input to end display is received (Yes in step S8), the data management device 1 ends the display process. If No in step S2, the data management device 1 proceeds to step S4, if No in step S4, the data management device 1 proceeds to step S6, and if No in step S6, the data management device 1 proceeds to step S8. If No in step S8, the data management device 1 repeats the process from step S2.

[0042] The procedure shown in Fig. 2 is one example, and it is sufficient if display processing according to input can be similarly performed, and the specific order and content of processing are not limited to the example shown in Fig. 2. In addition, the display screens shown in Fig. 3 and Fig. 4 are also one example, and the detailed layout, display method, input reception method, etc. are not limited to the examples shown in Fig. 3 and Fig. 4.

[0043] As described above, in this embodiment, the data management device 1 displays information about the electricity market corresponding to multiple areas as graphs of the same color, and highlights the graph corresponding to the area selected by the user. This makes it possible to provide information about the electricity market related to multiple electricity transmission and distribution companies all at once. In addition, it is easy for the user to visually recognize information about the area that the user wants to focus on.

[0044] Furthermore, in the example shown in Figure 1, the data management device 1 displays information about the electricity market, but this is not limited to this. Alternatively, the user may be able to check information about the electricity market on their terminal device, as in another configuration example described below.

[0045] Fig. 5 is a diagram showing another example of the configuration of a data management system including a data management device according to an embodiment. In the example shown in Fig. 5, a data management system 100a includes a data management device 1a, a bid support device 3, and a terminal device 4. Components having the same functions as those in the example shown in Fig. 1 are assigned the same reference numerals as in Fig. 1, and redundant explanations will be omitted.

[0046] The data management device 1a is similar to the data management device 1 shown in FIG. 1 except that it includes a transceiver 18 instead of the input acceptance unit 13 and the data display unit 17. When the transceiver 18 receives a request from the terminal device 4 to display information related to the electricity market, it instructs the display control unit 16 to start display processing.
