  The logged-in contract server 14 transmits and outputs the power sale condition input screen displayed in FIG. 4A to the power seller terminal 12 and the power purchase condition displayed in FIG. The input screen is transmitted and output (S103).

  As shown in FIG. 4 (a), the power sale condition is made up of information related to power sale, such as the name of the power seller, the location of the power generation facility, the power sale power, the power sale period, etc., and is entered on the power sale condition input screen. (S104).

  As shown in FIG. 4 (b), the power purchase condition includes information related to power purchase, such as the name of the power purchaser, the load facility location, the power purchase power, the power purchase period, etc., and is entered on the power purchase condition input screen. (S105).

  The power sale condition and the power purchase condition are respectively transmitted from the power seller terminal 12 and the power purchaser terminal 13 to the contract server 14 and recorded in the trade condition database 69 by the contract server 14 (S106).

  The contract server 14 determines whether or not there is a match between the power sale condition and the power purchase condition recorded in the trading condition database 69, and determines whether or not the transmission line network can be used. A determination is made based on the transmission line usage information recorded in the information database 67 (S107). Even if the power sale conditions and the power purchase conditions are met, if the transmission line network cannot be used, the sales contract cannot be executed, so the transmission line usage information is taken into consideration.

  FIG. 7 illustrates an example of power transmission line usage information recorded in the power transmission line usage information database 67.

  Here, as a power transmission possible range for each transmission line section, the range is described by a residence display or the like, for example, XX town 1-chome.

  Then, referring to the information on the power generation facility location and the load facility location input on the power sale condition input screen and the power purchase condition input screen, a transmission that can connect the power generation facility and the load facility from the power transmission possible range. A wire section is required.

  Therefore, the power generation facility 21 in FIG. 1 is determined as a transmission line section a for the load facility 22 and the transmission line section d for the load facility 22 is determined as a connection transmission line section. Usage information is used effectively.

  The transmission line usage information further describes a transmission line section to which each transmission line section can be connected. As a result, there is a transmission line section between the transmission line section a and the transmission line section d. As a result, two routes (power transmission line section a → b → c → d, power transmission line section a → e → f → g → d) are determined as a power transmission line network.

  When the purchased power input at this time exceeds one of the consignment capacities of each transmission line section, the transmission line network is excluded from the contract target.

  For example, in both the above two routes, when the purchased power exceeds one of the consignment capacities of each transmission line section, the consignment contract is not established, and in either case, the transmission line network is in the consignment contract. It becomes a target.

  If there is a power sale contract that matches the power sale and purchase conditions recorded here, and there are multiple transmission line networks used for this power sale contract, form a transmission line network. A transmission line network selection input screen posted with transmission line quality information included in the transmission line usage information of each transmission line section is transmitted to the power buyer terminal 13 (S108).

  Even when there is only one transmission line network used for the power purchase contract, the display of the transmission line network and information on the power purchase and sale are included in addition to the selection column as shown in FIG. The transmission line network selection input screen is transmitted.

  Further, in order to facilitate the selection of the transmission line section, as shown in FIG. 6, in response to a request from the power seller terminal 12 or the power purchaser terminal 13, each transmission line forming the transmission line network and the transmission line network is shown. It is possible to display a schematic diagram of the electric wire section, a consignment fee for each transmission line section, a transmission line accident rate as transmission line quality information, and a transmission line installation date as other information in a list format.

  The power purchaser inputs the transmission line section selection information and the like on this transmission line network selection screen with reference to the quality information of the transmission line section and transmits it to the contract server 14 (S109).

  In the above, transmission line network selection input screen information is transmitted from the management server 10 to the power purchaser terminal 13, the power purchaser is allowed to select a transmission line section, and the management server 10 inputs the input from the power purchaser terminal 13. The management server 10 transmits the transmission line network selection input screen information from the management server 10 to the power seller terminal 12, causes the power seller to select a transmission line section, and inputs the input from the power seller terminal 12 to the management server. 10 can be received (not shown).

  Also, transmission line network selection input screen information is transmitted from the management server 10 to both the power purchaser terminal 13 and the power sale terminal 12, and the power purchaser and the power sale person are allowed to select a transmission line section. (Not shown).

  In the consignment use of the transmission line section that forms the transmission line network based on the power sales contract, when there is a conflict with a third party, the bid is managed by the bid management means 64 and the use of the transmission line section was awarded by this bid. When there is no competition (S111) or when there is no competition (S110), there is no problem in the power purchase contract.

  As an example, the bidding method (S111) by the bidding management means 64 transmits a screen (not shown) for inputting information indicating that a bid has been placed and the amount of money for bidding, and requests an increase in the usage fee for the transmission line section. , Use is permitted to those who reach the highest price. Therefore, the person who lost the bid cannot conclude a power purchase contract using the transmission line section.

  When a bid is made for the use of the transmission line section by bidding (S111), or when there is no competition (S110), the contract server 14 buys and sells confirmation information that asks the seller terminal 12 and the buyer terminal 13 to confirm the sale, That is, the sales contract establishment confirmation request information is output and transmitted (S112).

  At this time, the screen output unit 63 includes at least information on the section consignment contract fee determined for each transmission line section forming the transmission line network used in the established power sales contract in the sales contract establishment confirmation request information. To function.

  For example, as the sales contract establishment confirmation request information, as shown in FIG. 6, information including at least information on the consignment fee of each transmission line section is included from the contract server 14 to the power seller terminal 12 and the power purchaser. It is output to the terminal 13.

  Therefore, at least the power purchaser who operates the power purchaser terminal 13 can conclude an electric power sales contract after grasping the section consignment contract fee determined for each transmission line section, and the fairness of the consignment fee And transparency can be improved.

  When the purchase confirmation information is replied from the power seller terminal 12 or the power purchaser terminal 13 (S113), the contract registration means 65 of the contract server 14 sends information on the power sale contract and the transmission line network to be used. By recording in the electric wire utilization information database 67 (S114), the role of the contract server 14 in the electric power sales contract is completed.

  Next, an example of operation of this system by the operation server 15 after the power sales contract is established and registered will be described with reference to FIG.

  As shown in FIG. 3, the operation server 15 acquires the measured values of the power / electricity meters 51 and 53 at predetermined time intervals through the communication line 11 by the terminals 55 and 56 (S201).

The power / power amount measuring means 73 determines whether or not the measured value is in the normal range (S202). The measured value is in the normal range, for example, it is determined whether it is the time to calculate the consignment fee etc. when it is used within the range specified in the power sales contract (S203). When it is time, the fee calculation means 75 calculates a consignment fee based on the measured value, and in some cases, an electric power purchase amount based on an electric power sales contract (S204).

  For example, as is recorded in the transmission line usage information shown in FIG. 7, the consignment fee is a basic fee (a predetermined period determined by the consignment contract power). And a usage fee of a pay-as-you-go fee determined by the amount of power transferred, a seasonal fee that increases or decreases depending on the season, a late-night fee, and the like.

  The unit price of the basic charge and usage charge can be determined by the length, year, and capacity of the transmission line in order to ensure fairness for consignment users.

  Then, the calculated consignment fee and the measured power amount are recorded in the contractor usage record database 77 in association with each power sales contract (S205). At this time, information on the power purchaser who is the contractor and the power seller is also recorded.

  The contents recorded in the contractor usage record database 77 are transmitted to the power seller terminal 12 and the power purchaser terminal 13 to notify the person at the time of the contract at the same time (S206).

  When the above measured value is not within the normal range, the circuit breaker control signal output means 76 sends a circuit breaker signal to the circuit breaker equipment 52 or circuit breaker equipment 54 in order to shut off the power transmission line by the circuit breaker according to a predetermined condition. It is transmitted (S207).

  The interruption signal is transmitted when the power buyer uses an excessive amount of power that violates the power purchase contract or when the power generation amount of the power seller is less than the predetermined amount. The contract will be blocked as a failure or non-performance. Even if it is against the contract, a surcharge can be imposed instead of blocking.

  When a blocking signal is transmitted or when an extra charge is imposed, the fact is recorded in the contractor usage record database 76 (S208). This is because it will be a record of evidence later.

  When the circuit breaker facilities 52, 53, etc. are interrupted, it is then determined whether the circuit breaker should be restored (S209). For example, it is necessary to execute an electric power sales contract by restoring the circuit breaker when overuse of electric power or the like is resolved and subsequent use in the normal range can be confirmed.

  When the circuit breaker is restored, the fact that the circuit breaker has been restored is recorded in the contractor usage record database 76 (S210).

  Thus, according to the system and method of the present invention, the power consignment contract fee can be obtained as the sum of the section consignment contract fees determined for each power line section forming the power line network for performing power consignment. This makes it possible to construct a fee system that takes into account the transmission distance and power transmission facilities, and to ensure the fairness of the power consignment contract fee.

  In addition, the power line section that forms the power transmission line network is displayed with quality information indicating the reliability of the transmission line section, enabling the purchaser to select the power line section. Can do.

  The bid management means 64 creates a bid input screen based on a predetermined bid condition when receiving an application for transmission line use in a section where no transmission line is stretched, and via the screen output means 63 And a function of determining a person who acquires the right to use the power transmission line in the section where the power transmission line is not stretched based on the information input to the bid management means 64 according to the output. .

  Here, the right to use a transmission line in a section where a transmission line is not stretched is, for example, a future transmission line is stretched in a section where a current transmission line is not stretched, and the transmission line is used. This refers to the title or the like that can be charged for the above-mentioned consignment fee when power consignment is performed.

  For example, in the embodiment shown in FIG. 1, when the transmission line is not yet stretched in the power transmission section indicated by the reference numeral 30 between the substation 33 and the substation 36, the management server 10 has the bid management means 64. Such a function can be used to sell the right to use the transmission line in the section between the substation 33 and the substation 36 by bidding.

  In this case, for example, the management server 10 has a power transmission section where no power transmission line is stretched between the substation 33 and the substation 36, and sells the right to use the power transmission line in this section by bidding. Information is published via the image output means 63.

  On the other hand, when there is an application from the power selling terminal 12, the power purchaser terminal 13, or a terminal that has accessed the management server 10 via the network 11, the bid management means 64 sets a predetermined bid. A bid input screen based on the conditions is created and output via the screen output means 63, and a transmission line in a section where no transmission line is stretched based on information input to the bid management means 64 according to the screen Decide who gets the right to use.

  As a result, bidders and successful bidders will be able to pay a consignment fee for power transmission using the transmission line when a future transmission line is extended for a transmission section where the transmission line is not currently extended. On the other hand, the administrator of the management server 10 can construct the power transmission line facility using the money obtained by selling this right as funds.
