  First, the terminal device 100 will be described. As illustrated in FIG. 3, the terminal device 100 includes an input device 710, a display device 720, and a control device 750. In particular, the control device 750 includes a file storage unit 751, a communication unit 752, and a control unit 753. The file storage unit 751 is realized by the HDD 200E described above, for example. The communication unit 752 is realized by the network I / F 200D described above, for example. The control unit 753 is realized by the CPU 200A and the RAM 200B described above, for example.

  The file storage unit 751 stores an electronic file (hereinafter simply referred to as a file) transmitted from the server device 200 and a file installed in the control device 750. The files stored in the file storage unit 751 include not only data files but also program files. In addition, although mentioned later for details, the file memory | storage part 751 contains the data showing the model (henceforth a model LC) of the Load Curve (LC: electric power load curve) designated as the characteristic of the consumer which an electric power provider wants to acquire. Remember the file. LC represents the transition of power consumption.

  The communication unit 752 controls communication between the terminal device 100 and the server device 200. For example, the communication unit 752 receives a file or data transmitted from the server device 200 or transmits display request data to the server device 200. The control unit 753 controls the overall operation of the terminal device 100. For example, upon receiving an instruction input from the input device 710, the control unit 753 changes the display content of the display device 720 according to the content of the instruction, or causes the communication unit 752 to transmit display request data and various data. To do. For example, when the communication unit 752 receives a file transmitted from the server device 200, the control unit 753 stores the received file in the file storage unit 751. In addition, the control unit 753 executes various data processing.

  Next, the server device 200 will be described. As illustrated in FIG. 3, the server device 200 includes a model LC storage unit 210, an actual LC storage unit 220, and a representative LC storage unit 230. In addition, the server device 200 includes a model LC creation unit 240, a representative LC creation unit 250, and a similar customer identification unit 260 as processing units.

  The model LC storage unit 210, the actual LC storage unit 220, and the representative LC storage unit 230 are realized by the HDD 200E described above, for example. The model LC creating unit 240, the representative LC creating unit 250, and the similar customer specifying unit 260 are realized by the CPU 200A and the RAM 200B described above, for example.

The house identification unit 260 may be provided.

  The model LC storage unit 210 stores model LC data (hereinafter referred to as model LC data). The model LC data is data representing the model LC. As shown in FIG. 4A, the model LC storage unit 210 manages and stores model LC data for each model ID using a plurality of model LC tables T1. The model LC table T1 includes a model ID, a model LC name, and a power amount for each time zone as components. The model ID represents identification information for identifying model LC data. The model LC name represents the name of the model LC. The amount of power represents the amount of power used (kWh). For example, a power usage amount “1.10 (kWh)” is registered in a time zone “00:30” representing time “00:00” to time “0:30”. For example, the power consumption is not registered (or NULL is registered) in the time zone “12:30” representing the time from “12:00” to “12:30”. Thus, in the model LC data, a time zone in which the power usage amount is registered and a time zone in which the power usage amount is not registered are mixed. As will be described in detail later, a set of time zones in which power usage is registered is referred to as a first time zone, and a set of time zones in which no power usage is registered is referred to as a second time zone. The first time zone and the second time zone each represent a partial time zone of one day. For example, the first time zone includes a plurality of separated time zones in one day, and the second time zone corresponds to a time zone different from the plurality of separated time zones.

  The actual LC storage unit 220 stores actual LC data (hereinafter referred to as actual LC data). The actual LC data is data representing the LC related to the actual amount of power used by the customer. As shown in FIG. 4B, the actual LC storage unit 220 manages and stores the actual LC data for each customer ID by using a plurality of actual LC tables T2. That is, the actual LC storage unit 220 stores actual LC data of a plurality of customers for a plurality of days in units of one day. The actual LC table T2 includes a customer ID, a customer name, a date, and a power amount for each time zone as components. The customer ID represents identification information for identifying the customer. The customer name represents the name of the customer. The date represents the date of power use. As described above, the amount of power represents the amount of power used (kWh). Unlike the model LC data described above, in the actual LC data, in principle, the power usage is registered in all time zones, and there is no time zone in which the power usage is not registered. However, the actual LC data may include a time zone in which the power usage amount is not registered. As described above, the actual LC storage unit 220 stores the usage histories of the power usage amounts of a plurality of consumers.

  The representative LC storage unit 230 stores representative LC data (hereinafter referred to as representative LC data). The representative LC data is data representing a representative value of the actual LC data having characteristics similar to the model LC data in the first time zone described above. The representative value may be an average value, for example. As shown in FIG. 5, the representative LC storage unit 230 manages and stores representative LC data for each representative ID using the representative LC table T3. Although details will be described later, when a plurality of representative LC data is created, the representative LC storage unit 230 manages and stores the representative LC data by the representative LC table T3 corresponding to the number of created representative LC data. May be. The representative LC table T3 includes a representative ID, a representative LC name, a date, and a power amount for each time zone as components. The representative ID represents identification information for identifying representative LC data. The representative LC name represents the name of the representative LC. The year / month / day represents a creation year and an arbitrary month / day (MMDD) set when the representative LC data is created. As described above, the amount of power represents the amount of power used (kWh). Since the representative LC data is created based on the actual LC data in the same way as the actual LC data described above, in the representative LC data, the power usage is registered in all time zones in principle, and the power usage is registered. There is basically no time zone that is not set.

  Returning to FIG. 3, the model LC creation unit 240 creates a model LC. More specifically, when the model LC creation unit 240 receives the first time zone and the designation of the power usage amount in the first time zone, based on the received first time zone and the designation of the power usage amount. Create a model LC. In addition, when the model LC creation unit 240 accepts the designation, the model LC creation unit 240 stores each time zone belonging to the accepted first time zone and the power usage amount of the time zone in the model LC storage unit 210 in association with each other. Thereby, the model LC storage unit 210 stores the model LC data.

The representative LC creation unit 250 creates a representative LC. More specifically, when the representative LC creation unit 250 accepts a file including model LC data (hereinafter referred to as a model LC file) and setting data to be described later, it extracts actual LC data corresponding to the setting data from the actual LC storage unit 220. The model LC data included in the model LC file is averaged for each consumer, and the actual LC data averaged for each consumer is limited to the first time zone and compared. Then, the representative LC creation unit 250 extracts averaged actual LC data whose features are similar to the model LC data in the first time zone, and calculates an average value of the extracted actual LC data for each consumer. By doing so, representative LC data is created. For example, the representative LC creating unit 250 may create the representative LC data by calculating the average value of the extracted actual LC data for each time zone. Thereby, representative LC data classified into a plurality of time zone groups is obtained. When the representative LC creation unit 250 creates the representative LC data, the representative LC creation unit 250 stores the created representative LC data in the representative LC storage unit 230.
In addition, when the representative LC creating unit 250 extracts averaged performance LC data whose characteristics are similar to those of the model LC data in the first time zone, the condition of the customer including the residential area of the customer, the family structure, etc. May be extracted, and averaged performance LC data of consumers that have similar characteristics to the model LC data in the first time zone and that meet the received conditions may be extracted. In this case, the server device 200 may have a consumer information storage unit that stores the residential area and family structure of the consumer in association with the consumer ID.

  The similar customer specifying unit 260 extracts and specifies a customer associated with actual LC data similar to the representative LC data. More specifically, the similar customer specifying unit 260 acquires representative LC data from the representative LC storage unit 230 and also acquires actual LC data from the actual LC storage unit 220. When acquiring the representative LC data and the actual LC data, the similar customer specifying unit 260 extracts and specifies the customer ID and the customer name associated with the actual LC data similar to the representative LC data. When the similar customer specifying unit 260 specifies the customer ID and the customer name, the customer ID and the customer name are transmitted to the terminal device 100 together with the representative LC data and the actual LC data as the similar customer. When receiving the similar consumer, the representative LC data, and the actual LC data, the terminal device 100 displays the similar consumer, the representative LC represented by the representative LC data, and the actual LC represented by the actual LC data. Thereby, the person in charge of an electric power company can confirm the similar consumer according to model LC.

  Next, with reference to FIG. 6 to FIG. 8, operations related to creation of the model LC of the terminal device 100 and the server device 200 will be described.

  FIG. 6 is a flowchart illustrating an example of the operation of the terminal device 100. FIG. 7 is a flowchart showing an example of the operation of the server device 200. FIG. 8 is an example of a model LC creation screen.

  First, as illustrated in FIG. 6, the control unit 753 of the terminal device 100 waits until receiving an instruction to activate the model LC creation screen from the input device 710 (step S <b> 101: NO). Upon receiving an instruction to activate the model LC creation screen (step S101; YES), the control unit 753 generates first display request data for requesting the model LC creation screen, and the communication unit 752 generates the first display request data generated by the control unit 753. 1 display request data is transmitted to the server apparatus 200.

  On the other hand, as illustrated in FIG. 7, the model LC creation unit 240 of the server device 200 stands by until a model LC creation screen is requested (step S <b> 201: NO). When the model LC creation screen is requested (step S201: YES), the model LC creation unit 240 transmits the first screen data (step S202). More specifically, when the model LC creation unit 240 receives the first display request data transmitted from the terminal device 100, the model LC creation unit 240 transmits the first screen data toward the terminal device 100. The first screen data is data representing the model LC creation screen. When the process of step S202 is completed, the model LC creation unit 240 waits until it accepts the electric energy data (step S203: NO).

  Returning to FIG. 6, when the communication unit 752 of the terminal device 100 receives the first screen data transmitted from the server device 200 (step S102), the display device 720 displays a model LC creation screen (step S103). More specifically, when the communication unit 752 receives the first screen data, the control unit 753 displays the model LC creation screen on the display device 720 based on the first screen data received by the communication unit 752. Thereby, as shown in FIG. 8, the display device 720 displays a model LC creation screen. When the process of step S103 is completed, the control unit 753 waits until the power usage amount is input (step S104: NO).

  Here, as shown in FIG. 8, the model LC creation screen includes a first area AR1, a second area AR2, and a third area AR3. The first area AR1 includes a plurality of input fields Bx1 associated with a plurality of time zones every 30 minutes. The second area is an area for displaying the model LC. The third area AR3 is an area instructing to download the model LC. A part of the time zone in the first area AR1 and the second area AR2 is omitted. When the display device 720 displays the model LC creation screen, the person in charge of the electric power company inputs a numerical value representing the amount of power used in part or all of the input field Bx1 through the input device 710.

  Returning to FIG. 6, when the control unit 753 determines that the power usage amount has been input (step S <b> 104: YES), the communication unit 752 transmits the power usage amount data representing the input power usage amount to the server device 200. (Step S105). Moving to FIG. 7, when the model LC creation unit 240 of the server device 200 receives the power usage data (step S203: YES), the model LC creation unit 240 creates model LC data (step S204). More specifically, upon receiving the power usage data, the model LC creation unit 240 creates model LC data in which the received power usage data is associated with the time zone of the power usage data, and the created model LC data Is stored in the model LC storage unit 210. When the process of step S204 is completed, the model LC creation unit 240 transmits the created model LC data to the terminal device 100 (step S205), and waits until a download is requested (step S206: NO). If download is not requested, the process returns to step S203, and the model LC creation unit 240 waits until it accepts power consumption data again.

  Returning to FIG. 6, when the communication unit 752 of the terminal device 100 receives the model LC data transmitted from the server device 200 (step S106), the display device 720 displays the model LC (step S107). More specifically, when the communication unit 752 receives model LC data, the control unit 753 displays the model LC on the display device 720 based on the model LC data received by the communication unit 752. Thereby, as shown in FIG. 8, the display device 720 displays the model LC in the first time zone in the second display area AR2.

  When the process of step S107 is completed, the control unit 753 determines whether or not the download button has been pressed (step S108). When the control unit 753 determines that the download button has not been pressed (step S108: NO), the control unit 753 returns to the process of step S104. Therefore, the power usage amount can be input to the input field Bx1 until the download button Bt1 is pressed on the model LC creation screen shown in FIG. For this reason, power usage amount data is transmitted each time a numerical value representing the power usage amount is input to the plurality of input fields Bx1 of the first display area AR1. As a result, the model LC creation unit 240 creates model LC data each time it receives power usage data, stores the created model LC data in the model LC storage unit 210, and directs the model LC data to the terminal device 100. To send.

  If the control unit 753 determines that the download button has been pressed (step S108: YES), it issues model LC file download request data, and the communication unit 752 transmits the download request data to the server device 200. Then, upon receiving the download request data, the model LC creation unit 240 of the server device 200 determines that the download is requested (step S206: YES), and creates a model LC file (step S207). For example, the model LC creation unit 240 acquires model LC data for one day stored in the model LC storage unit 210 and creates a model LC file.

  When the process of step S207 is completed, the model LC creation unit 240 transmits the model LC file to the terminal device 100 (step S208), and the process ends. When the model LC creation unit 240 transmits the model LC file, the communication unit 752 receives the model LC file as shown in FIG. 6 (step S109). When the communication unit 752 receives the model LC file, the control unit 753 stores the model LC file received by the communication unit 752 in the file storage unit 751 and ends the process.

  Next, with reference to FIG. 9 to FIG. 17, operations related to creation of the representative LC of the terminal device 100 and the server device 200 will be described.

  First, as illustrated in FIG. 9, the control unit 753 of the terminal device 100 waits until receiving an instruction to activate the representative LC creation screen from the input device 710 (step S <b> 301: NO). When the control unit 753 receives an instruction to start the representative LC creation screen (step S301; YES), the control unit 753 generates second display request data for requesting the representative LC creation screen, and the communication unit 752 generates the second display request data generated by the control unit 753. 2 display request data is transmitted to the server apparatus 200.

  On the other hand, as shown in FIG. 10, the representative LC creation unit 250 of the server device 200 stands by until a representative LC creation screen is requested (step S401: NO). When the representative LC creation screen is requested (step S401: YES), the representative LC creation unit 250 transmits the second screen data (step S402). More specifically, when the representative LC creation unit 250 receives the second display request data transmitted from the terminal device 100, the representative LC creation unit 250 transmits the second screen data to the terminal device 100. The second screen data is data representing a representative LC creation screen. When the process of step S402 is completed, the representative LC creation unit 250 waits until setting data is received (step S403: NO).

  Returning to FIG. 9, when the communication unit 752 of the terminal device 100 receives the second screen data transmitted from the server device 200 (step S302), the display device 720 displays a representative LC creation screen (step S303). More specifically, when the communication unit 752 receives the second screen data, the control unit 753 displays the representative LC creation screen on the display device 720 based on the second screen data received by the communication unit 752. Thereby, as shown in FIG. 11, the display device 720 displays a representative LC creation screen.

The fourth area AR4 includes an input field Bx1 for specifying the file name of the model LC to be uploaded, an input field Bx1 for specifying the name of the representative LC, and an input field Bx1 for inputting the creation year. For example, when the reference button Bt2 is pressed, the control unit 753 acquires the model LC file from the file storage unit 751 and causes the display device 720 to display the model LC file. As a result, the file name of the model LC file is displayed in the input field Bx1 for designating the file name of the model LC. The fifth area AR5 is an area for designating conditions for extracting the actual LC based on the model LC. For example, when selecting the target period by inputting a check to the selection field Bx2 for selecting the month and the selection field Bx2 for selecting the day of the week, the actual LC data regarding the selected month and day of the week is extracted and averaged, A representative LC is created. Note that other selection columns (not shown) may be provided in the fifth area AR5. The sixth area AR6 is an area for designating matching conditions and matching criteria between the representative LC and the averaged result LC. Part or all of the contents input and selected for the fourth area AR4, the fifth area AR5, and the sixth area AR6 are transmitted to the server apparatus 200 as setting data.

  Returning to FIG. 9, when the setting data is input to the control unit 753 (step S304: YES), the communication unit 752 transmits the setting data (step S305). More specifically, when the execution button Bt3 included in the representative LC creation screen shown in FIG. 11 is pressed, the control unit 753 confirms the setting data input status, and then the communication unit 752 transmits the setting data. On the other hand, as shown in FIG. 10, when the representative LC creation unit 250 of the server device 200 receives the setting data (step S403: YES), the representative LC creation unit 250 creates representative LC data (step S404). More specifically, when the representative LC creation unit 250 receives the setting data, the representative LC creation unit 250 extracts the actual LC data of a plurality of consumers from the actual LC storage unit 220, averages the number of days for each customer, and sets The model LC data of the model LC file received as data is compared with the characteristics. Then, the representative LC creation unit 250 specifies averaged performance LC data whose similarity with the model LC data belongs to a predetermined similarity range. Thereby, the some performance LC data averaged for every consumer is obtained. When the representative LC creation unit 250 identifies the averaged actual LC data, the representative LC data for each specified consumer is averaged to create representative LC data, and the created representative LC data is stored in the representative LC storage unit 230. .

  More specifically, with reference to FIG. 12, the representative LC creation unit 250 averages the number of days of the month and day of the week selected in the fifth area AR5 (see FIG. 11) only in the first time zone. The characteristics of the actual LC for each customer expressed by the actual LC data and the model LC expressed by the model LC data are compared. Then, the representative LC creation unit 250 identifies the actual LC for each customer whose similarity with the model LC belongs to the predetermined similarity range. When the representative LC creation unit 250 specifies the actual LC for each consumer, the representative LC for each specified consumer is averaged to create a representative LC as shown in FIG. The representative LC data representing the representative LC created by the representative LC creating unit 250 is stored in the representative LC storage unit 230.

  In the model LC creation screen (see FIG. 8) already described, for example, when power consumption for one time zone is input and power usage for the remaining 47 time zones is not input, FIG. As shown, a model LC in which the amount of power used for one time zone appears is created. Comparing the characteristics of such a model LC and the actual LC, it is sufficient that there is an actual LC similar to the power consumption of this one time zone, and therefore the number of similar actual LCs tends to increase.

  Conversely, in the model LC creation screen (see FIG. 8), for example, when power consumption for 48 time zones is input, a model in which power usage for 48 time zones appears as shown in FIG. LC is created. Comparing the features of the model LC and the actual LC, it is sufficient that there is an actual LC similar to the power consumption of 48 time zones, but the number of similar actual LCs tends to decrease. Therefore, when the number of power consumptions input on the model LC creation screen is a predetermined number (for example, 5) or less or a predetermined number (for example, 40) or more, the control unit 753 is input. A warning screen may be displayed on the display device 720 to warn that the number of used power is not appropriate.

  Returning to FIG. 10, when the process of step S404 is completed, the similar consumer specifying unit 260 matches the representative LC data and the actual LC data (step S405), and specifies the similar consumer (step S406). Specifically, as shown in FIG. 16, the representative LC represented by the representative LC data and the actual LC data of the month and day selected in the fifth area AR5 (see FIG. 11) are averaged by customer. Each result LC expressed by this is matched as a whole without limiting the first time zone and the second time zone. At this time, as shown in FIG. 17, using the setting data (specifically, matching conditions and matching criteria) set on the representative LC creation screen (refer to FIG. 11), the similar consumer specifying unit 260 can display the representative LC. Match each achievement LC.

For example, when the representative LC power consumption within ± 0.5 kWh is set as the matching condition, as shown in FIG. 17, the lower limit LC and the representative LC power usage obtained by reducing 0.5 kWh from the representative LC power consumption. An upper limit LC is created by increasing 0.5 kWh from the amount. And the similar consumer specific | specification part 260 specifies the track record LC which satisfies a matching reference | standard within the range of the created lower limit LC and upper limit LC. For example, the matching criteria “90%”, “70%”, “65%” for the four time zones from the time zone “00:30 to 06:00” to the time zone “18:30 to 24:00”, respectively. ”And“ 95% ”are set, as shown in FIG. 17, the actual LC satisfying the matching condition is specified for each time period. Furthermore, when the matching criterion “85%” is set for the entire power consumption by 48 time periods, as shown in FIG. 17, the actual LC satisfying the matching condition as a whole is specified.
FIG. 17 shows an example in which a day is equally divided into four time zones with a width of 6 hours. However, the way of dividing the time zones is not limited equally, and the time zones that emphasize features are more detailed. The time zone may be divided so that it can be set.

  When the similar customer specifying unit 260 specifies the actual LC, the similar customer is extracted and specified as a similar customer. And if the similar consumer specific | specification part 260 specifies a similar consumer, as shown in FIG. 10, a similar consumer, representative LC data, and performance LC data will be transmitted toward the terminal device 100 (step S407), and processing will be carried out. finish. Similar customers include at least one of a customer ID and a customer name.

  Returning to FIG. 9, when the similar customer specifying unit 260 transmits the similar customer, the representative LC data, and the actual LC data, the communication unit 752 receives the similar customer, the representative LC data, and the actual LC data (step S306). When the process of step S306 is completed, the control unit 753 displays the similar consumer, the representative LC, and the actual LC received by the communication unit 752 on the display device 720 (step S307), and ends the process. As a result, the display device 720 displays the similar LC, the representative LC expressed by the representative LC data, and the actual LC expressed by the actual LC data. For example, the display device 720 may display the number of customers in addition to the customer ID and the customer name as similar customers.

  The control unit 753 may display the similar consumer, the representative LC, and the actual LC in the above-described representative LC creation screen, or the similar customer, the representative LC, and the actual LC on a different screen from the representative LC creation screen. May be displayed in a distinguishable manner. In addition, the control unit 753 may display the similar consumer, the representative LC, and the actual LC on different screens that are different or partially different from each other, or display the similar consumer, the representative LC, and the actual LC on one different screen. May be. As a result, the representative LC described with reference to FIG. 16 and similar customer LCs are displayed on the display device 720.
