The discount calculation unit 114 adds a consumption tax to the received annual expected electricity price and notifies the bid registration unit 115 of the added consumption tax. The bid registration 115 adds the bid information to the corresponding bid item information when receiving the annual expected electricity charge.

  The bid item DB 108 is a database that stores the bid item ID of each bid item, the bid item information, and the bid information corresponding to the bid item as shown in FIG. 4 in association with each other. . The contract type DB 109 is a database that stores a power supplier ID, a contract type ID, basic information, and correction information for each contract type of each power supplier as shown in FIG. The network 200 is a network installed in a wide area such as the Internet, and is connected to the electrical contract mediation apparatus 100, the power consumer terminals 300a to 300z, and the power supplier terminals 301a to 301z. The power consumer terminals 300 a to 300 z are terminals owned by a business operator who desires to purchase power and are connected to the electrical contract mediation apparatus 100 via the network 200. The power supplier terminals 301 a to 301 z are terminals owned by a general scale electric power company or a specific scale electric power company that desires to sell electric power, and are connected to the electric contract mediation apparatus 100 via the network 200. .

  Next, the operation of the electric contract mediation apparatus 100 will be described. Prior to conducting the electric contract brokerage service, first, the power supplier terminals 301a to 301z, for all contract types of the owner, as shown in each record of FIG. Type ID), basic information (contract type name, region code, bid type, maximum contract power, supply voltage, basic charge, unit price, renewable energy rate), correction information (load pattern, load adjustment value 1, load adjustment value) 2, seasonal variation, seasonal adjustment value 1, seasonal adjustment value 2) are transmitted to the contract type condition registration processing 106 of the electric contract brokerage apparatus 100 based on the input of the owner. The communication control unit 101 of the electrical contract mediation apparatus 100 receives the information via the network 200 and then notifies the contract type condition registration processing 106. Upon receiving this information, the contract type condition registration processing 106 creates one record for one contract type in the contract type DB 109 and registers it as shown in FIG.

  Next, for example, the bid contract information of the electric contract of the building owned by the owner of the power consumer terminal 300a is the bid shown in FIG. 3 from the power consumer terminal 300a. This is sent to the case registration process 102. The communication control unit 101 of the electrical contract mediation apparatus 100 receives these pieces of information via the network 200 and then notifies the bid item registration process 102. When receiving the information, the bid item registration process 102 assigns an identification number (for example, 0352) to the bid item, sets this as a bid item ID, and together with the received information, the bid item DB 108 as shown in FIG. Register with. When the registration is completed, the bid item registration process 102 notifies the automatic bidding process 107 of an automatic bid start request together with the bid item ID “0352” of the previously registered bid item.

  When the automatic bidding process 107 receives the bid item ID and the start request, the contract type selection unit 110 of the automatic bidding process 107 uses the bid item DB 108 here as the contract condition of the bid item of the bid item ID “0352”. The maximum contract power “20,000 KW” and the received voltage “6,000 V” are read out. Next, the automatic bidding process 107 extracts the contract type power supplier ID and contract type ID satisfying the contract condition from the contract type DB 109. That is, here, since the maximum contract power is 20,000 KW or more and the supply voltage is 6,000 V, all the contract types registered in records 1 to 3 satisfy the contract conditions, and the power The supplier ID and contract type IDs “01, 01”, “01, 02”, and “02, 01” are read out. Next, the contract type selection unit 110 notifies the pattern correction unit 111 of these power supplier ID and contract type ID.

  When the pattern correction unit 111 receives the power supplier ID and the contract type ID, the pattern correction unit 111 performs a correction based on the load pattern and a correction based on the seasonal variation on the unit price. First, the case where the contract type is “01, 01” with the power supplier ID and the contract type ID will be described as an example. The pattern correction unit 111 reads the load pattern (in this case, “1006, 995, 996, 1015, 1105, 1367” from the bid item DB 108 in order to perform correction based on the load pattern, from the bid item DB (bid item ID “0352”). , 1927, 2114, 2498, 2913, 3344, 3627, 3323, 3645, 3611, 3344, 3019, 2585, 2423, 2119, 1775, 1413, 1224, 1009 "), and the contract type ( The unit price “11.75” of the power supplier ID and the contract type ID “01,01”, the relative load pattern (here, “16, 16, 16, 16, 15, 14, 12, 11, 10, 9”) , 8, 6, 6, 6, 7, 8, 10, 11, 12, 14, 15, 16, 16, 16 ), The load adjustment value 1 "0.15", it reads out the "1" load adjustment value 2, by substituting the equation [Expression 1], obtaining a usage-based bids corrected.

In the formula [Equation 1], a _i represents the electric energy from 0 o'clock to 23 o'clock in the load pattern for each of i = 1 to 24 read from the bid item DB 108, and A is from 0 o'clock to 23 o'clock Represents the total amount of power in the load pattern. B _i represents the value of the relative load pattern read from the contract type DB 108 for each of i = 1 to 24 from 0 o'clock to 23 o'clock, and B represents the value of the relative load pattern from 0 o'clock to 23 o'clock. Represents the sum of Here, the load pattern and the relative load pattern are substituted to obtain A = 52498, B = 286, and the deviation value is “0.665”. Further, the load adjustment value 1 “0.15” and the load adjustment value 2 “1” are substituted into the formula [Equation 1], and the unit price “11.75” is substituted into the unit price before correction, so that the load pattern The unit price “17.80” after correction according to is obtained.

  Next, in order to perform correction due to seasonal fluctuations, the pattern correction unit 111 reads from the bid item DB 108 the amount of power (from here to December) of the previous year's performance of the bid item (bid item ID “0352”). , “67519, 55234, 52591, 52498, 51064, 62136, 76559, 78149, 65128, 51248, 57851, 63124”), from the contract type DB 109, the contract type (power supplier ID and contract type ID “01, 01”) ), Seasonal variation (here, “13, 13, 12, 13, 14, 1720, 20, 15, 10, 11, 12”), seasonal adjustment value 1 “0.1”, seasonal adjustment value 2 “1” And the metered unit price “17.80” corrected by the load pattern is used as the pre-correction metered unit price, together with these read values. Then, substituting into the equation [Equation 2], the unit price after correction due to seasonal variation is obtained.

In the formula [Equation 2], n _j represents the amount of electric power from January to December in the previous year results read from the bid item DB 108 where j = 1 to 12, and N represents the electric power in the previous year results from January to December. Represents the total amount. Also, _{m i} is, i = 1 to 12 each represent a value of 12 months from January previous year read from contract type DB 108, M represents a sum of the values of the seasonal variations of the 12 months from January. Here, since the seasonal variation is substituted and N = 733001 and M = 170, the deviation value is “0.116”. Furthermore, the seasonal variation adjustment value 1 “0.1” and the seasonal variation adjustment value 2 “1” are substituted into the formula [Equation 2], and the unit price “17.80” corrected by the load pattern is set to the value before correction. By substituting into the unit price, a corrected unit price “18.09”, which is corrected by the load pattern and seasonal variation, is obtained.

  The pattern correction unit 111 similarly calculates the corrected unit price for the remaining contract types (power supplier ID and contract type IDs “01, 02”, “02, 01”) that have been notified. Here, when the power supplier ID and the contract type ID are “01, 02”, the corrected unit price is “14.33”, and when the power supplier ID and the contract type ID is “02, 01”, the corrected unit price is “14,33”. Is a unit price “17.28”. When correction of the pay-per-use unit price is completed for all contract types that have received the notification, the pattern correction unit 111 corresponds to the power supplier ID and the contract type ID received from the contract type selection unit 110 by the consignment shipping fee correction unit 112 In addition, the metered unit price after each correction is notified.

  When receiving the corrected unit price associated with the power supplier ID and the contract type ID, the commission postage correction unit 112 adds the commission postage. For example, assuming that the postage to be added in each region is the value shown in FIG. 6, when the power supplier ID and the contract type ID are “01, 01”, the corresponding record in the contract type DB 109 (here Then, referring to the region code (here Tohoku) of the record 1) and the region code (here Tokyo) of the corresponding record (here the record of the bid item ID “0352”) in the bid item DB 108, From FIG. 6, “2.1” in Tohoku and “3.0” in Tokyo are added to the unit price “18.09” and the unit price is “23.19”. Similarly, in the case of other contract types, when the power supply ID and the contract type ID are “01, 02”, the unit price “16.33” in which 2.1 in Tohoku and 3.0 in Tokyo are also notified. "19.43". When the power supply ID and the contract type ID are “02, 01”, the region code (here, Hokkaido) of the corresponding record (here, record 3) in the contract type DB 109 and the corresponding record (here) in the bid item DB 108 Then, referring to the region code (Tokyo in this case) of the bid item ID “0352”, notify “1.5” in Hokkaido, “2.1” in Tohoku, and “3.0” in Tokyo. In addition to the measured unit price “17.28”, “23.88” is obtained. When the addition of the commission fee is finished for all the contract types that have received the notification, the commission fee correction unit 112 corresponds to the power supplier ID and the contract type ID received from the pattern correction unit 111 by the electricity charge calculation unit 113. In addition, the unit price per unit after adding each commission is notified.

  When receiving the metered unit price after adding the commission fee associated with the power supplier ID and the contract type ID, the electric charge calculating unit 113 calculates an annual electric charge for each notified contract type. Monthly electricity charges are expressed as “basic charge + metered unit price x electricity amount”, so the monthly electricity charges from January to December are calculated using this formula, and these are added together. The annual electricity charge. First, the electricity bill for January with the power supplier ID and contract type ID “01, 01” is the basic charge of the corresponding record (here, record 1) in the contract type DB 109 and the corresponding record in the bid item DB 108. (Here, the record of the bid item ID “0352”) From the amount of electricity in January of the previous year actual result and the notified unit price, 501,000 yen + 23.19 yen / KWh × 67,519 kWh = 2,066,765 .61 yen. Similarly for each month after February, “17881876.46, 1720585.29, 17184428.62, 1685174.16, 19493933.84, 227404.21, 2313275.31, 201318.32, 168941.12, 1842564. 69, 1964845.56 ", and the total from January to December is 23,010,293.19 yen. Similarly, the annual electricity charge for the power supplier ID and contract type ID “01,02” is 15,292,209.43 yen, and the year for the power supplier ID and contract type ID “02,01”. The electricity bill will be 18,488,063.88 yen. When the calculation of the annual electricity bill is completed for all the contract types that have received the notification, the electricity bill calculation unit 113 receives the power supplier ID and the contract type that have been notified to the tax calculation unit 114 from the consignment postage correction unit 112. Each year's electricity bill is notified in association with the ID.

  Upon receiving the annual electricity charge associated with the power supplier ID and the contract type ID, the tax calculation unit 114 adds 5% consumption tax to the annual electricity charge for each notified contract type, Calculate the annual electricity bill. Here, the expected annual electricity bill with the power supplier ID and contract type ID “01,02” is multiplied by 1.05 to the notified annual electricity bill “23,010,293.19” to be 24, It will be 160,907.85 yen. Similarly, the expected annual electricity bill for the power supplier ID and contract type ID “01,02” is 16,056,819.9 yen, and the power supplier ID and contract type ID is “02,01”. The annual electricity bill is 19,412,467.07 yen. When the calculation of the annual expected electricity rate is completed for all contract types that have been notified, the tax calculation unit 114 determines the power supplier ID and the contract type ID that the bid registration unit 115 has received from the electricity rate calculation unit 113. In correspondence with, each annual expected electricity rate is notified.

  When the bid registration unit 115 receives the annual expected electricity price associated with the power supplier ID and the contract type ID, the bid registration unit 115 selects the one with the lowest annual expected electricity price from the same power supplier ID, Register in DB108. Here, for the power supplier ID “01”, if the contract type ID is “01”, the annual expected electricity charge is 24,160,907.85 yen, and the contract with the same power supplier ID “01” is used. If the type ID is “02”, the annual expected electricity charge is 16,056,819.9 yen, so the bid information with the annual expected electricity charge of the contract type ID “02” is registered in the bid item DB 108. At this time, the bid identification ID is “0352001” by concatenating the bidding information serial number to the bid item ID, and the bid status, area code, contract maximum power, received voltage, basic charge, unit price before correction, and regeneration energy ratio Refers to the contract type DB 109 and registers the value calculated in the commission postage correction 112 as the corrected unit price. Further, since the contract type ID is only “01” for the power supplier ID “02”, the bid information for the contract type is registered in the same manner and the process is terminated. As a result, the information shown in FIG. 4 is registered in the bid item DB 108 in association with the bid item ID “0352”.

  Next, it is assumed that the power supplier ID of the power supplier terminal 301a is “01”. When the owner of the power supplier terminal 301 a instructs to check the bid status, the power supplier terminal 301 a transmits a bid status request to the electrical contract mediation apparatus 100 via the network 200. When receiving the bid status request, the communication control unit 101 of the electrical contract mediation apparatus 100 notifies the bid status inquiry processing 103 of this request. When receiving a bid status request, the bid status inquiry process 103 refers to the bid item DB 108 and returns all bid item IDs and contract conditions of the registered bid items before the bid deadline. Here, since the bid cases before the bid deadline are only the bid cases with the bid case ID: “0352”, the bid case ID “0352” and its contract conditions (electric power consumer ID “105”, region code “Tokyo”, The communication control unit 101 is notified of the bid deadline “20XX / 08/31”, the maximum contract power “20,000”, and the receiving voltage “6,000”. The communication control unit 101 that has received the notification transmits the notification to the power supplier terminal 301a as a reply to the bid status request via the network 200. The power supplier terminal 301a displays a list of received bid item IDs and contract conditions. Here, since the received bid item ID is only “0352”, only this one item is displayed.

  When the owner of the power supplier terminal 301a selects this bid item and instructs the power supplier terminal 301a to display the results of the previous year, the power supplier terminal 301a is connected to the electric contract mediation apparatus 100 via the network 200. The previous year result request is transmitted together with the bid item ID “0352”. Upon receiving the bid item ID “0352” and the previous year result request, the communication control unit 101 of the electrical contract mediation apparatus 100 notifies the bid situation inquiry processing 103 of these. Upon receiving these notifications, the bid status inquiry process 103 refers to the bid item DB 108 to inform the communication control unit 101 of the power amount and the electric charge from January to December of the previous year's actual result of the bid item ID “0352”. Notice. Receiving the notification, the communication control unit 101 transmits the notification to the power supplier terminal 301a via the network 200 as a reply to the previous year result request. The power supplier terminal 301a displays a list of received power amounts and electricity charges in the previous year.

  Next, when the user selects the bid item ID “0352” again and instructs the power supplier terminal 301 a to display the bid status, the power supplier terminal 301 a receives the electric contract brokerage via the network 200. A bid status request is transmitted to the apparatus 100 together with a bid item ID “0352”. Upon receiving the bid item ID “0352” and the bid status request, the communication control unit 101 of the electrical contract mediation apparatus 100 notifies the bid status inquiry processing 103 of these. Upon receiving these notifications, the bid status inquiry process 103 refers to the bid item DB 108 and bid information (bid identification ID, bid state, power supply ID, region code, contract type ID, bid item ID “0352”). "Contract maximum power, received voltage, basic charge, unit price before correction, unit price after correction, discount rate, annual expected electricity rate, renewable energy ratio". Here, the registered bid information is shown in FIG. Since the bid identifications shown in FIG. 2 are bid information of “0352001” and “0352002”, these are notified to the communication control unit 101. The communication control unit 101 that has received the notification transmits a reply to the bid status request via the network 200. The notification is transmitted to the power supplier terminal 301a, and the power supplier terminal 301a displays the received bid information, where the bid status is a provisional bid. In some cases, the owner can change their annual expected electricity bill, which is their bid, by changing the base rate, adjusted pay-as-you-go, or setting a discounted rate, Since the owner of the power supplier terminal 301a is the lowest price among the bidders, the bid is confirmed at the same price without changing the annual expected electricity charge, and the bid identification ID “ The power supplier terminal 301a transmits the instruction to the electric contract brokerage apparatus 100 via the network 200. The communication control unit 101 of the electric contract brokerage apparatus 100 transmits the instruction to the bid confirmation “0352001”. In response, the bid change / confirmation process 104 is notified to the bid change / confirmation process 104. When the bid change / confirmation process 104 receives the notice, the bid identification ID of the bid item DB 108 is “035200”. The tender state of the record of the "change in the bidding, to determine the bid.

  When time has passed and the bid deadline of the bid item has passed, the successful bid notification processing 105 refers to the bid item DB 108, and the bid status is “bid” in the bid information of the bid item. Assuming that the bid information with the lowest electricity price has been awarded, the bid status of the bid information is changed to “successful bid” and the power consumption of the power supplier terminal of the power supplier who is the successful bidder and the setter of the bid project Notification to the user terminal. In this example, the annual expected electricity charge of the bid identification ID “0352001” is 16,056,819,9 yen, and the annual expected electricity charge of the bid identification ID “0352002” is 19,412,467.07 yen. It is a successful bid with the bid identification ID “035001”. Therefore, the successful bid notification process 105 instructs the communication control unit 101 to notify the power consumer terminal 300a and the power supplier terminal 301a of the successful bid result. Upon receiving the successful bid result notification instruction, the communication control unit 101 transmits the successful bid result notification to the power consumer terminal 300a and the power supplier terminal 301a via the network 200.

  Prior to the bidding deadline, it is possible to check the bidding status from the power consumer terminal 300a that has set a bid item, as in the case of the power supplier terminal 301a. Furthermore, a successful bid can be designated from the power consumer terminal that has set a bid item if it is before the bid deadline. For example, after confirming the bidding status at the power consumer terminal 300a for which a bid item has been set, the power consumer terminal 300a receives a bid information and a successful bid instruction from the owner, and then the power consumer terminal 300a Transmits a bid identification ID (for example, “02”) of the instructed bid information and a notification of successful bid to the electric contract mediation apparatus 100 via the network 200. Upon receiving the notification, the communication control unit 101 of the electrical contract mediation apparatus 100 notifies the bid change / confirmation process 104 of the notification. Upon receiving the notification, the bid change / confirmation process 104 changes the bid state of the record of the bid identification ID notified of the bid identification ID of the bid item DB to a successful bid according to the notification. When the bidding status of the record is changed to a successful bid, the successful bid notification process 105 includes the power consumer terminal 300a of the power consumer of the bid item and the power supplier of the power supplier of the bid information that has won the bid item. The communication control unit 101 is instructed to notify the terminal 301b of the successful bid result. Upon receiving the successful bid result notification instruction, the communication control unit 101 transmits the successful bid result notification to the power consumer terminal 300a and the power supplier terminal 301b via the network 200.

  The commission postage correction unit 112 refers to the region code of the corresponding record in the contract type DB 109 and the region code of the relevant record in the bid item DB 108 to determine the consignment postage of the electric power company in each region that entrusts power. Although described as adding to the unit price, the consignment shipping cost of the power company in the area that consumes the power may be added to the unit price. In this case, for example, when the power supplier ID and the contract type ID are “01, 01” and the bid item ID is “0352”, the region code of the bid item that is the region that consumes power is “Tokyo”. 6, “3.0” in Tokyo is added to the unit price “18.09”, and the unit price is “21.09”. Also, in the case of other contract types, when the bid item ID is “0352”, it depends only on the area where the consignment fee is consumed, so “3.0” of Tokyo is added to each unit price. .
