  As illustrated in FIG. 1, the server 4 includes a storage unit 41, an information acquisition unit 42, an information generation unit 43, and a communication unit 44. The communication unit 44 is connected to the wide area network 300, and the communication unit 25 of the power management apparatus 2 and the communication unit 44 of the server 4 can communicate with each other via the wide area network 300.

  The operation of the fee structure selection support system will be described below.

  First, the power management apparatus 2 installed in association with each of the plurality of consumers 900 is based on the amount of power purchased by the consumers 900 and the electricity rate system contracted by the consumers 900. The electricity bill (monthly electricity bill) for each customer 900 during (target period) is calculated periodically. Then, the power management device 2 transmits to the server 4 data on monthly electricity charges, data on various types of electricity in the consumer 900, and data on the electricity charge system contracted by the consumer 900.

  Specifically, the measurement unit 1 periodically measures actual demand power, purchased power, self-consumption power, and power sales power, and each measurement result of actual demand power, purchase power, self-power consumption, and power sales power Is wirelessly transmitted to the power management apparatus 2. The wireless communication unit 26 of the power management apparatus 2 receives the measurement results of actual demand power, purchased power, self-consumption power, and power sales power from the measurement unit 1.

  The data management unit 22 integrates the actual demand power, the purchased power, the self-consumed power, and the sold power every hour. Then, the data management unit 22 stores (stores) the result of time integration of the actual demand power in the storage unit 21 as data of the actual demand power amount for each hour. In addition, the data management unit 22 stores the result of time-integrating the purchased power in the storage unit 21 as data of the purchased power amount per hour. Further, the data management unit 22 stores the result of time integration of the self-power consumption in the storage unit 21 as self-power consumption data for each hour. Further, the data management unit 22 stores the result of time integration of the power sale power in the storage unit 21 as data of the power sale power amount for every hour. Further, when the measurement unit 1 does not have a function of measuring purchased power, the data management unit 22 calculates the power purchase amount based on a calculation formula of [power purchase amount = actual demand power amount−self power consumption amount]. May be.

  Furthermore, the storage unit 21 also stores data on the electricity billing system contracted with the customer 900 and data on the power selling unit price. The data on the electricity rate system is data on the type of electricity rate system and the electricity rate unit price (unit price for electricity purchase) for each time zone, and corresponds to the electricity rate system contracted by the consumer 900. The unit price data is applied when the generated power is sold. The data on the electricity bill system and the data on the power sale unit price are stored in the storage unit 21 in advance.

  Specifically, the data management unit 22 creates a data table (see Table 1) in which the hourly actual demand power amount, power purchase amount, self-consumption power amount, power sale power amount, and electricity bill unit price are associated with the date and time. Generated and stored in the storage unit 21. That is, the storage unit 21 stores various power histories in the customer 900 in association with the unit price of the electricity bill. Here, there is a relation of [amount of power purchased = amount of actual demand power−amount of power consumed by itself].

  And the electric power calculation part 24 calculates the sum total (monthly electric power purchase amount) of the electric power purchase amount in the last one month (target period) in the consumer 900. FIG.

  Further, the charge calculating unit 23 refers to the data table shown in Table 1 to calculate the electricity charge (monthly electricity charge) for the most recent month (target period) in the customer 900, and to obtain the monthly electricity charge data. Create as data on electricity charges. The charge calculation unit 23 periodically performs the process for creating the monthly electricity charge data (for example, every day, every week, every month, etc.). The electricity charge is obtained by {(amount of electricity purchased × unit price of electricity charge) − (amount of electricity sold × unit price of electricity sale)}. The amount of electric power sold × the electric power selling unit price is the electric power sales income of the electric power consumer in the consumer 900. The monthly power purchase data and the monthly electricity bill data are generated corresponding to the same target period (one month).

  The communication unit 25 periodically receives the data on the monthly power purchase amount at the consumer 900, the data on the monthly electricity bill at the consumer 900, and the data on the electricity bill system contracted by the consumer 900 (for example, every day Or every week or every month).

  In the server 4, the communication unit 44 receives a plurality of data on the monthly power purchase amount at the consumer 900, data on the monthly electricity bill at the consumer 900, and data on the electricity bill system contracted by the consumer 900. Received from each of the power management devices 2 of the consumer 900. Each data received by the communication unit 44 is stored in the storage unit 41. Table 2 shows a data table stored in the storage unit 41. This data table associates customer information, monthly power purchase amount, monthly electricity bill, electricity bill system, and last update date with each other. Composed. The customer information is configured by identification information (ID), a residence, and a user name predetermined for each customer 900. And the power management apparatus 2 is communicating with the server 4 using the identification information of the corresponding consumer 900, and the server 4 is based on the identification information of the consumer 900 given to the received data. Thus, the power management device 2 that is the data transmission source is distinguished. In addition, the server 4 holds in advance information on correspondence between the identification information of the customer 900, the residence, and the user name.

  In the monthly power purchase amount in the data table of Table 2, the latest data of the monthly power purchase amount received from each power management device 2 of the plurality of consumers 900 is stored. In the monthly electricity rate in the data table of Table 2, the latest data of the monthly electricity rate received from each power management device 2 of the plurality of consumers 900 is stored. In the electricity rate system of the data table of Table 2, the latest data of the electricity rate system received from each power management apparatus 2 of the plurality of consumers 900 is stored. In the last update date of the data table of Table 2, the latest update date of each data of the plurality of consumers 900 is stored.

  That is, the storage unit 41 stores a plurality of power information, a plurality of fee information, and a plurality of fee structure information corresponding to each of the plurality of consumers 900. Each of the plurality of pieces of power information is information regarding the monthly power purchase amount purchased by the corresponding consumer 900. Each of the plurality of charge information is information regarding the electricity charge at the corresponding customer 900. Each of the plurality of charge system information is information on the electricity charge system in the corresponding customer 900. That is, the server 4 stores the monthly power purchase amount data received by the communication unit 44 in the storage unit 41 as the power information, the monthly electricity bill data as the fee information, and the electricity bill system data as the fee system information. To do.

  Then, the server 4 creates support information for supporting the selection of the electricity rate system for each of the power consumers of all the customers 900 to be managed by the server 4, and Support information is transmitted to the corresponding display terminal 3.

  First, the information acquisition unit 42 sets one customer as a support information creation target as the first customer 901 from all the customers 900 as management targets. Then, the information acquisition unit 42 acquires the data of the monthly power purchase amount at the first consumer 901 from the storage unit 41. And the information acquisition part 42 extracts the consumer which can be considered that the monthly power purchase amount is the same rank as the 1st consumer 901 as the 2nd consumer 902 from all the consumers 900 used as management object.

  Specifically, the information acquisition unit 42 sets a threshold W1 obtained by adding a predetermined value to the monthly power purchase amount P1 at the first consumer 901 (see FIG. 3), and the monthly power purchase amount is a threshold W1 or more. Are extracted as second consumers 902.

  Alternatively, the information acquisition unit 42 sets a predetermined range W2 that is equal to or greater than the monthly power purchase amount P1 at the first consumer 901 (see FIG. 4), and sets a plurality of consumers whose monthly power purchase amount falls within the range W2. The second consumer 902 may be extracted.

  In addition, when the number of the extracted plurality of second consumers 902 is greater than a predetermined value, the information acquisition unit 42 sets the above-described threshold W1 further lower or sets the above-described range W2 more narrowly. The second customer 902 can be extracted within a predetermined value.

  And the information acquisition part 42 acquires the electric power information regarding the monthly electric power purchase amount in the said 2nd consumer 902 among the some electric power information from the memory | storage part 41 with respect to each of the several 2nd consumer 902. FIG. For each of the plurality of second consumers 902, the information acquisition unit 42 further acquires, from the storage unit 41, charge information related to a monthly electricity charge at the second consumer 902 among the plurality of charge information. For each of the plurality of second consumers 902, the information acquisition unit 42 acquires, from the storage unit 41, charge system information related to the electricity charge system at the second consumer 902 among the plurality of charge system information. The information generation unit 43 generates support information including at least the power information, fee information, and fee structure information acquired by the information acquisition unit 42. This support information is message information, and includes information on monthly power purchases at the first consumer 901, monthly electricity charges, electricity billing system, monthly electricity purchases at the plurality of second consumers 902, and monthly electricity charges. Each information of electricity rate system is included. And as for support information, it is preferable to rank-display each data of the 1st consumer 901 and the some 2nd consumer 902 in order with a low monthly electricity bill. Furthermore, when the area information of the consumer 900 (such as a prefecture with the second consumer 902) is stored in the storage unit 41, it is also preferable to include the area information of the plurality of second consumers 902 in the support information.

  The communication unit 44 sends support information whose destination is the display terminal 3 corresponding to the first consumer 901 to the wide area network 300. When the communication unit 25 of the power management apparatus 2 of the first consumer 901 receives support information via the wide area network 300, the wireless communication unit 26 transmits the support information to the display terminal 3 by wireless communication. That is, the power management apparatus 2 relays communication between the server 4 and the display terminal 3.

  The display terminal 3 displays the received support information on the screen. FIG. 5 shows a display example of the support information, in which the data of the first consumer 901 and the second consumer 902 are ranked and displayed in ascending order of monthly electricity charges. Note that the server 4 notifies the display terminal 3 of the first consumer 901 of URL (Uniform Resource Locator) information storing the support information, and the display terminal 3 displays the support information by accessing this URL. May be.

  The power consumer of the first consumer 901 can compare the monthly electricity bill and the monthly power purchase amount with other consumers (second consumer 902) by looking at the support information displayed on the display terminal 3. it can. Therefore, if the monthly electricity rate of the second consumer 902 whose monthly power purchase amount is in the same rank is lower than that of the first consumer 901, the power consumer of the first consumer 901 has the second consumer 902. It is possible to consider changing to an electricity bill system.

  That is, the server 4 obtains information on the second consumer 902 that uses electricity at a lower price than the first consumer 901 (information on the second consumer 902 whose monthly electricity rate ranking is higher than the first consumer). The display terminal 3 of the first consumer 901 is notified. Thus, the server 4 can notify the first consumer 901 of the electricity billing system of the second consumer 902 who uses electricity at a reasonable price as the recommended electricity billing system. As a result, when the server 4 informs the electricity consumer of the first consumer 901 of the recommended electricity billing system, the server 4 gives a sense of loss based on the current electricity billing system, not a profitable feeling. The change can be prompted to the power consumer of the first consumer 901. Therefore, the charge system selection support system of this embodiment can make the electric power consumer of the 1st consumer 901 decide the change to the electricity charge system which a consumer satisfies.

  Moreover, it is preferable that the information acquisition part 42 adds that the monthly electricity bill is lower than the 1st consumer 901 to the extraction conditions of the 2nd consumer 902. In this case, the information acquisition unit 42 can refer to the storage unit 41 and consider that the monthly power purchase amount is in the same rank as the first consumer 901 and the monthly electricity bill is lower than the first consumer 901. A consumer is extracted as the second consumer 902. Thus, as the second consumer 902, only information on a consumer whose monthly electricity bill is lower than that of the first consumer 901 is presented. Therefore, in this system, only the information on the electricity charge system that is economically satisfactory is presented to the power consumer of the first consumer 901, and the electricity charge system is changed to the power consumer of the first consumer 901. Can be more strongly encouraged.

  Furthermore, it is preferable that the information acquisition part 42 extracts the 2nd consumer 902 using the attribute of the consumer 900. FIG. For example, each of the plurality of power management apparatuses 2 causes the attribute data of the corresponding customer 900 to be transmitted from the communication unit 25 (data transmission unit) to the server 4. The server 4 stores the received attribute data in the storage unit 41 in association with the customer 900 corresponding to the power management apparatus 2 that is the transmission source. The information acquisition unit 42 adds to the extraction condition of the second consumer 902 that the attribute matches the first consumer 901.

  Specifically, the attributes of the customer 900 include the region where the customer 900 is located, the personnel configuration (family configuration) in the customer 900, the presence / absence of distributed power sources such as solar cells, fuel cells, and wind power generators, and distribution The power generation capacity of the power source, the building conditions, the main electricity usage hours, etc. The building conditions are the total floor area of the building of the customer 900, the floor plan, the wooden structure / reinforced concrete structure, and the like. The main electricity usage time zone is a time zone (daytime / nighttime) in which electricity is mainly used by the consumer 900. The attribute of this consumer 900 is written in the memory | storage part 21 by operation of the electric power consumer of the consumer 900, and the memory | storage part 21 has stored the attribute of the corresponding consumer 900. FIG.

  Then, the power management apparatus 2 periodically transmits the attribute data in the storage unit 21 to the server 4. The server 4 stores the received attribute data in the storage unit 41 in association with the customer 900 corresponding to the power management apparatus 2 that is the transmission source.

  In this case, the information acquisition unit 42 can refer to the storage unit 41 and consider that the monthly power purchase amount is in the same rank as the first consumer 901 and a demand that matches the attribute of the first consumer 901. The house is extracted as the second consumer 902. The information acquisition unit 42 may extract the second consumer 902 that matches all the attributes set for the first consumer 901, or out of all the attributes set for the first consumer 901. You may extract the 2nd consumer 902 which corresponds to a predetermined number or more of attributes.

  In general, the attribute of the consumer 900 affects the power purchase amount and the electricity rate of the consumer 900. Therefore, even if the monthly power purchase amount is the second consumer 902 in the same rank as the first consumer 901, if each attribute of the first consumer 901 and the second consumer 902 is different, a suitable electricity billing system can be obtained. The first consumer 901 and the second consumer 902 may be different. For example, the amount of electricity purchased and the electricity price fluctuate depending on the climate of the area where the consumer 900 is located and the weather conditions, and the amount of electricity purchased and the electricity price increase as the number of family members in the consumer 900 increases, and the building is wide. The amount of electricity purchased and the electricity bill will increase. In addition, in the customer 900 who adopts the charge according to the time zone such as “Morning Plan”, “Night Value Plan”, and “Half Day Plan”, the electricity is concentrated in the time zone where the electricity unit price is low. There is a tendency to use, and the time zone in which electricity is concentrated and used for each consumer 900 is different.

  Therefore, the information acquisition unit 42 adds to the extraction condition of the second consumer 902 that the attribute matches that of the first consumer 901. Therefore, the information acquisition part 42 can extract only the 2nd consumer 902 which has the same attribute of the 1st consumer 901, and can show the electric bill system more suitable with respect to the 1st consumer 901. Further, the power consumer of the first consumer 901 becomes a reference in selecting the electricity rate system in the first consumer 901 as the type of attribute data stored in the storage unit 21 of the power management apparatus 2 is increased. The extraction accuracy of the two consumers 902 can be improved.

  Moreover, it is preferable that the information generation part 43 includes the attribute information of the 2nd consumer 902 in support information. In this case, the power consumer of the first consumer 901 can know the attributes necessary for further reducing the electricity bill with reference to the attribute information of the second consumer 902 displayed on the display terminal 3. .

  Moreover, the information acquisition part 42 can add to the extraction condition of the 2nd consumer 902 that the 1st consumer 901 and an electricity bill system correspond. In this case, by including the attribute information of the second consumer 902 in the support information, the power consumer of the first consumer 901 can confirm the attribute of the second consumer 902 that adopts the same electricity rate system. preferable. For example, in the case of the first consumer 901 adopting the time zone charge system, referring to the attribute of the second consumer 902 that purchases electricity at a discount while using the same time zone charge system. It is possible to find a method that can further suppress the electricity bill. Here, the charge system for each time zone is a charge system in which the unit price of electricity charges (unit price of power purchase) varies from time to time.

  Note that the power management apparatus 2 may be configured with, for example, a HEMS (Home Energy Management System) controller. In this case, the measuring unit 1 has a function of measuring the power (branch power) consumed in each of the branch electric circuits 101, and the power management device 2 can determine the branch power of each of the branch electric circuits 101 of a plurality of systems. A HEMS (Home Energy Management System) is constructed using the data. In HEMS, the power management apparatus 2 has a function of visualizing power consumption by presenting branch power data to an appropriate presentation apparatus. In HEMS, the power management apparatus 2 has a function of controlling the electric device 200 for the purpose of power saving based on the branch power data.

  The fee structure support system of the above-described embodiment includes a storage unit 41, an information acquisition unit 42, an information generation unit 43, a plurality of display terminals 3, and a communication unit 44.

  The storage unit 41 includes a plurality of pieces of power information related to the amount of power purchased by each of the plurality of consumers 900, a plurality of pieces of charge information related to the electricity charges of each of the plurality of consumers 900, and the electricity of each of the plurality of consumers 900. A plurality of fee structure information related to the fee structure is stored.

  The information acquisition unit 42 includes the second consumer 902 to which the power purchase amount in the target period belongs within the range of the power purchase amount including the range exceeding the power purchase amount in the target period of the first consumer 901 among the plurality of consumers 900. Are extracted from a plurality of consumers 900. And the information acquisition part 42 acquires the electric power information regarding the electric power purchase amount purchased in the object period by the 2nd consumer 902 among several electric power information from the memory | storage part 41. FIG. The information acquisition unit 42 further includes charge information related to the electricity charge of the second consumer 902 in the target period among the plurality of charge information, and charge structure information related to the electricity charge structure of the second consumer 902 among the plurality of charge charge information. Obtained from the storage unit 41.

  The information generation unit 43 generates support information including power information, fee information, and fee structure information acquired by the information acquisition unit 42. Each of the plurality of display terminals 3 is associated with each of the plurality of consumers 900. The communication unit 44 transmits support information to the display terminal 3 corresponding to the first consumer 901 among the plurality of display terminals 3. The display terminal 3 corresponding to the first consumer 901 displays support information on the screen.

  Therefore, the charge system support system can make the power consumer of the first consumer 901 decide the change to the electrical charge system that the power consumer of the first consumer 901 is satisfied.
