The procedure for creating the supply facility registration information will be described with reference to the flow of FIG.

  In FIG. 4, the supply facility information registration unit 227 of the supply facility information terminal 205 waits for the supply / demand contract number to be input to the input device 214 (step 401). The supply and demand contract number is input to the input device 214 (step 402). When the supply / demand contract number is input to the input device 214 by the user of the supply facility 201, the supply facility information registration unit 227 transmits the supply / demand contract number to the control server 203 via the communication unit 217 (step 403). The communication unit 220 of the control server 203 receives the supply and demand contract number transmitted from the supply facility information terminal 205 (step 404). The supply facility information storage unit 228 determines whether or not the supply facility ID for the received supply-demand contract number has already been allocated (step 405). If the supply facility ID is already assigned to the supply and demand contract number, the supply facility registration information has already been registered, and therefore the registered supply facility registration information is supplied to the supply facility information terminal 205 via the communication unit 220. (Step 407). If the supply facility ID is not yet allocated to the supply and demand contract number, it is a new registration, so the supply facility information storage unit 228 allocates the supply facility ID and stores it in the storage device 219 as the supply facility registration information (step) 406). The supply facility information storage unit 228 transmits the supply facility registration information to the supply facility information terminal 205 via the communication unit 220 (step 407).

And a consumer name for setting an arbitrary character string for each consumer 202. Specific examples of customer names include restaurant names, elementary school names, company names, and facility names.

  FIG. 6 shows customer registration information held by the control server 203, and customer setting information and customer IDs of the customer 202 are managed in a one-to-one correspondence. In FIG. 2, 229 is a customer information registration unit in which the customer information terminal 210 registers customer setting information in the control server 203, and 230 is based on the customer setting information transmitted from the customer information terminal 210. It is a customer information storage unit that allocates customer IDs and stores them in the storage device 224. A procedure for creating customer registration information will be described with reference to the flowchart of FIG.

  In FIG. 7, the customer information registration unit 229 of the customer information terminal 210 waits for customer setting information to be input to the input device 222 (step 701). The customer setting information is input from the user of the customer 202 to the input device 222 (step 702). When the customer setting information is input to the input device 222, the customer information registration unit 229 transmits the customer setting information to the control server 203 via the communication unit 225 (step 703). The communication unit 220 of the control server 203 receives the customer setting information transmitted from the customer information terminal 210 (step 704). The customer information storage unit 230 determines whether or not a customer ID for the received customer setting information has already been allocated (step 705). If the customer ID is already assigned to the customer registration information, the customer registration information has already been registered, so the registered customer registration information is sent to the customer information terminal via the communication unit 220. It transmits to 210 (step 707). If no customer facility ID is assigned to the customer setting information, it is a new registration, so the customer information storage unit 230 assigns a customer ID and stores it in the storage device 219 as customer registration information. (Step 706). The customer information storage unit 230 transmits customer registration information to the customer information terminal 210 via the communication unit 220 (step 707). The communication unit 225 of the customer information terminal 210 receives customer registration information transmitted from the control server 203 (step 708). The customer information registration unit 229 stores the customer registration information received from the control server 203 in the storage device 224 (step 709). The customer information registration unit 229 displays customer registration information on the display device 223 (step 710). As a result, customer registration information for uniquely identifying the customer 202 is held on the control server 203.

  In order to specify the supply destination of the power generated by the supply facility 201, it is necessary to determine what customers can be specified as the supply destination. A consumer who is a candidate for a supply destination is stored as customer registration information in the storage device 219 of the control server 203, and thus needs to acquire customer registration information from the control server 203. In FIG. 2, reference numeral 231 denotes a customer information acquisition unit from which the supply facility information terminal 205 acquires customer registration information from the control server 203. Reference numeral 232 denotes a customer registration stored in the storage device 219 of the control server 203. It is a customer information providing unit that transmits to the supply facility information terminal 205. A method in which the supply facility information terminal 205 acquires customer registration information from the control server 203 will be described with reference to the flow of FIG.

  8, the customer information acquisition unit 231 of the supply facility information terminal 205 waits for a customer registration information acquisition request to be input to the input device 214 (step 801). A customer registration information acquisition request is input from the user of the supply facility 201 to the input device 214 (step 802). When the customer registration information acquisition request is input to the input device 214, the customer information acquisition unit 231 transmits the customer registration information acquisition request to the control server via the communication device 217 (step 803). In the customer registration information acquisition request, a method for acquiring all customer IDs registered in the control server 203, a method for specifying customer IDs or group IDs, and a character string indicating a part or all of the customer name The method of specifying is mentioned. The communication unit 220 of the control server 203 receives the customer registration information acquisition request transmitted from the supply facility information terminal 205 (step 804). The customer information providing unit 232 acquires customer registration information corresponding to the content of the customer registration information acquisition request from the storage device 219 (step 805). If all customer IDs are specified in the customer registration information acquisition request, all customer IDs are acquired. If a group ID is specified, all customer IDs for that group ID are acquired, and demand is obtained. When a character string indicating a part or all of the house name is designated, a customer ID including the character string is acquired. The customer information providing unit 232 determines whether one or more pieces of customer registration information have been acquired from step 805 (step 806). When one or more pieces of customer registration information can be acquired, the customer information providing unit 232 transmits the customer registration information acquired via the communication unit 220 to the supply facility information terminal 205 (step 807). When there is no customer registration information, since there is no registered customer registration information, information without customer registration information is transmitted to the supply facility information terminal 205 via the communication unit 220 (step 808). The communication unit 217 of the supply facility information terminal 205 receives one or more pieces of customer registration information from the control server 203 (step 809). When one or more pieces of customer registration information are received, the customer information acquisition unit 231 stores the customer registration information in the storage device 216 (step 810). The customer information acquisition unit 231 displays a part or all of the acquired customer registration information on the display unit 215 (step 811). When the communication unit 217 of the supply facility information terminal 205 receives information without customer registration information from the control server 203 (step 812), the customer information acquisition unit 231 displays that there is no customer that can be specified as a supply destination. The information is displayed on the measure 215 (step 813). Thereby, the user of the supply facility 201 can acquire the candidate of the consumer who is the supply destination of the generated electric power, and can specify the supply destination from these.

  The user of the supply facility 201 designates the supply destination of the actually generated power from the list of consumers acquired by the customer information acquisition unit 231 and registers it in the control server 203. In FIG. 2, reference numeral 233 denotes a supply information registration unit that registers supply information in which information on how much power is supplied to a consumer who is a supply destination of power generated by the supply facility 201 is registered in the control server. And 234 is a supply information storage unit that stores the supply information received from the supply facility information terminal 205 in the storage device 219. A method in which the supply facility information terminal 205 registers supply information in the control server 203 will be described with reference to FIGS.

  FIG. 9 shows supply information set by the supply facility information terminal 205. A combination of a supply facility ID that is a power supply source and a customer ID that is a power supply destination is set. It is possible to set a supply ratio that sets which percentage of the electric power generated by the supply facility 201 is supplied to which consumer. The maximum supply amount that sets the maximum power supply amount for each consumer can be set. As a specific usage example, when the amount of power distributed according to the supply ratio exceeds the maximum supply amount, the control server 203 calculates that the maximum supply amount of power has been supplied to the consumer. When the maximum supply amount is not set, the amount of power that can be supplied by the supply facility 201 is the amount of power distributed by the supply ratio. It is possible to set a supply start date and a supply end date for setting a supply period of when to start supply and when to supply for each consumer. Based on the supply information received from the supply facility information terminal 205, the control server 203 creates a supply calendar for determining how much power can be supplied from which supply facility to which consumer. An example of a supply calendar is shown in FIG.

  In FIG. 10, it is set that how much power is supplied to a certain consumer at what supply ratio among the power generated on the supply day by a certain supply facility. In the example, the supply equipment with the supply equipment ID S001 is 40% of the electric power generated on January 1, 2011 or the maximum supply quantity 10kW, whichever is lower, the customer with the customer ID D001 It can be supplied to.

  In FIG. 11, one customer ID to be supplied with electric power is selected from the customer registration information displayed in step 811 (step 1101). A supply ratio, a maximum supply amount, a supply start date, and a supply end date are input from the input device 214 to the customer ID (step 1102). When it is desired to designate a plurality of consumers as supply destinations, it is determined whether there is a consumer for which supply information has not yet been set (step 1103). If there is, step 1101 and step 1102 are repeatedly executed, and supply information is set for all customers who want to be specified as supply destinations. When supply information is set for all consumers, the supply information registration unit 233 checks the consistency of the supply ratio (step 1104). Since the sum of the supply ratios for all consumers exceeds 100%, that is, it is not possible to supply a larger amount of power than the amount of generated power, consistency is confirmed. If consistency is not achieved, the supply ratio is reset in step 1102. When the consistency is obtained, the supply information registration unit 233 transmits the supply information to the control server via the communication unit 217 (step 1105). The communication unit 220 of the control server 203 receives supply information from the supply facility information terminal 205 (step 1106). The control server 203 that has received the supply information creates a supply calendar based on the received supply information in the supply information storage unit 234 and stores it in the storage device 219 (step 1107). The control server 203 transmits that the supply calendar has been registered to the supply facility information terminal 205 via the communication unit 220 (step 1108). The communication unit 217 of the supply facility information terminal 205 receives the registration result from the control server (step 1109). The supply information registration unit 233 displays on the display device 215 that supply information has been registered in the control server (step 1110).

  A method for calculating how much of the amount of power supplied from the supply facility 201 to the specified consumer 202 by the control server 203 according to the supply calendar will be described.

  235 periodically acquires the supply power amount transmitted from the communication device 209 of the supply facility fixing device 206 and the power consumption amount transmitted from the communication device 213 of the customer fixing device 211 via the communication device 220 of the control server 203. Then, based on the information of the supply calendar stored in the storage device 219, it is calculated which power is supplied from which supply facility to which consumer, and is stored in the storage device 219 as a supply / demand record (FIG. 13). This is the supply and demand record registration department.

  FIG. 12 is a flow chart for calculating supply and demand results processed by the supply and demand result registration unit 235 of the control server 203. The supply / demand record registration unit 235 confirms whether or not the maximum supply amount is set in the supply calendar (step 1201). When the maximum supply amount is not set, it is calculated as the actual supply and demand result and stored in the storage device 219 regardless of the value of power after being distributed according to the supply ratio (step 1204). When the maximum supply amount is set, the supply and demand results are calculated within a range where the generated power does not exceed the maximum supply amount. When power exceeding the maximum supply amount can be supplied, the supply power exceeding the maximum supply amount is calculated as a final surplus value (step 1202), and the final surplus value is stored in the storage device 219 (step 1203).

  FIG. 13 shows the supply and demand results calculated by the supply and demand result calculation flow of FIG. Although the actual power generation performance of the supply facility A101 in 2011/1/2 is 12 kW, since the maximum supply amount is set to 10 kW, the supply and demand performance is calculated as 10 kW, and the final surplus value is calculated as 2 kW. Supply facility A101 has a power generation record of 10kW in 2011/4/1, and the supply ratio to customer A103 and customer B104 is set to 4 to 6, so the supply and demand record is 4kW for customer A103. B104 is calculated as 6kW. The power generation performance of supply facility A101 on 4/2/2011 is 30 kW, and the power supplied to customer A103 is 12 kW, 40%, but the maximum supply is set to 10 kW, so the supply and demand performance is 10 kW. Calculated. On the other hand, the supply / demand power to the customer B104 is 18% of 60% and does not exceed the maximum supply amount of 20kW, so the actual supply / demand result is calculated as 18kW. Supply facility A101 has a power generation record of 4kW in 2011/4/3, both of which exceed the maximum supply, so the supply and demand record is 10kW for customer A103, 20kW for customer B104, and the final surplus is 6kW and 4kW. The total is calculated as 10kW.

  Through the above processing, supply equipment ID and customer ID that correspond one-to-one with the supply and demand contract number are used, and the supply equipment generates specific demand according to the preset ratio, maximum supply amount, and period. Can be supplied to the house. Thereby, the power generated by the supply facility can be supplied to a consumer who wants to supply power, and a power information management system reflecting the intention of the supply facility can be constructed. Since this system can be constructed, the choice of how to use the generated power will be expanded, and the generation facilities can be expected to spread.

  In the present embodiment, the supply information can be changed at an arbitrary timing intended by the user, and the supply calendar can be updated by transmitting the supply information from the supply information registration unit 233 to the control server 203.
