Description

  The present invention relates to a power receiving right transaction support system that supports a power receiving right transaction that is a right to receive power of a transaction target power receiving amount during a specific period.

  A power receiver that receives power from an electric power company such as an electric power company that has been engaged in the electric power business or a specific-scale electric power company that has newly entered the electric power business due to the liberalization of the electric power market, is the largest power consuming device owned by the power receiver. Decide the contract power reception amount according to the maximum power reception amount predicted from the total power consumption, etc., conclude a power supply and demand contract with the electric power company, and reduce the power reception amount to the contract power reception amount or less Consume power in a limited form. That is, the maximum allowable power reception amount that can be received by the power receiver is the contract power reception amount.

  The electric power company decides the scale of the power generation equipment and power supply equipment according to the total amount of contracted power received by each power receiver in order to ensure a certain level of reliability for each power receiver. The facility cost increases as the total amount of contracted power received increases, and accordingly, the basic fee paid by the power receiver to the electric utility is set higher as the contracted power amount increases.

  In addition, there is a case where the receiver wants to reduce the contracted power amount as much as possible to reduce the power charge, that is, improve the economic efficiency. However, the contracted power amount depends on the maximum power consumption of the receiver. Therefore, even if the receiver has a small amount of power received during a specific period such as nighttime or holiday, the contracted power reception amount cannot be lowered if the amount of power received is large during a period other than the specific period.

As a contract selectively concluded between an electric power company and a power receiver, there is a so-called “peak time adjustment contract” (selective contract).
In this type of peak time adjustment contract, especially during peak hours such as daytime when the total amount of power received by each power receiver is large, the contracted power amount of the power receiver, that is, the maximum allowable power receiving amount, is determined between the electric power company and the power receiver. It is a contract that will be reduced by the amount set by prior or occasional discussions. Such contracts are made on the electric utility side by reducing the contracted power amount of the power receivers during this peak time, thereby leveling the total amount of power received by each power receiver as much as possible, and overloading the power generation equipment. The purpose of this is to suppress the occurrence of accidents such as power outages due to the above, and further to reduce the scale of the power generation equipment to reduce the equipment cost.
On the other hand, a power receiver who has concluded a peak time adjustment contract as described above reduces the contract power amount within the peak time specified by the electric power provider, thereby reducing the price of the electric power provider in the form of a discount on the electricity bill. Can be received from.

As described above, in the peak time adjustment contract that is selectively concluded between the electric power company and the power receiver, the power receiver adjusts the maximum allowable power reception amount to a lower side than the initial contract power amount at the peak time. Thus, the consideration can be received from the electric power company, and therefore, a part of the power receiving right, which is the right that the power receiving person can receive the electric power up to the contracted electric power amount, is sold to the electric power company side.
Such a power right transaction is due to the convenience of the electric power company to level the total amount of power received by each power receiver as much as possible. It cannot be done against a third party other than the person. Conventionally, a power receiving transaction support system that supports such power receiving transaction has not been considered.

  For example, if a power receiver can sell a power reception right during a specific period, such as a night or holiday, when the power reception amount is relatively small, to a third party whose power reception amount is large during the specific period, the energy received by the power receiver Although it is thought that the cost can be reduced, when a power receiver of a general household, etc. sells such a power reception right, it recruits purchasers who wish to purchase the power reception right. It is difficult to adjust the maximum allowable power reception amount of both parties in order to establish a power reception right transaction with the purchaser.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to reduce the trouble of the seller and the purchaser in the transaction of the power receiving right that is the right to receive the power in a specific period in the power receiving receiver. A power receiving transaction support system that can be reasonably supported without spending, and that can reliably adjust the maximum allowable power receiving amount of both parties to execute the power receiving transaction. It is in the point to realize.

The power receiving right transaction support system according to the present invention for achieving the above object is a power receiving right transaction supporting system for supporting a power receiving right transaction, which is a right to receive the power of a transaction target power receiving amount in a specific period, The first characteristic configuration is a sale power reception right information acquisition means for acquiring sale power reception right information including a sale target power reception amount specified as a transaction target power reception amount by a seller who wishes to sell the power reception right;
Purchase power receiving right information acquisition means for acquiring purchase power receiving right information including a purchase target power receiving amount specified as a transaction target power receiving amount by a purchaser who wishes to purchase the power receiving right;
Transaction means for determining the amount of received power for transaction based on the sale power reception right information and the purchase power reception right information;
It is the point provided with the transaction object power-receiving right information output means which outputs the transaction object power-receiving right information including the transaction object power receiving amount determined by the transaction means to the seller side and the purchaser side.

According to the first characteristic configuration, the sale power receiving right information acquisition unit and the purchase power receiving right information acquisition unit seek a seller who wants to sell the power receiving right and a purchaser who wants to purchase the power receiving right. The sale power right information and the purchase power right information are acquired from the side, and between the seller and the purchaser based on the acquired sale power right information and the purchase power right information obtained by the transaction means. It is possible to rationally establish a power receiving right transaction between the seller and the purchaser in the form of determining the amount of power to be received in the power receiving right to be traded in it can.
Then, by outputting the transaction target power right information to both the seller side and the purchaser side by the transaction target power right information output means, the seller knows that the power right transaction has been established. During the period, the maximum allowable power received amount is adjusted to be reduced by the amount of power received for the transaction, while the purchaser knows that the transaction of the right to receive power has been established, and the buyer receives the maximum allowable power received during the specified period. By adjusting to the increase side by the amount, delivery of the power reception right from the seller to the purchaser can be surely executed.
The seller can sell the right to receive power for a specific period with a relatively small amount of power received to the purchaser, and the purchaser can receive the price for the specific period with a relatively large amount of power received. Since the maximum allowable power receiving amount can be temporarily increased by purchasing from the seller, the energy cost of the seller and the purchaser can be reduced.
In the present application, the amount of power received may be a power value (kW) received per unit time, or may be a value (kWh) obtained by time-integrating the power value.

According to a second characteristic configuration of the power receiving transaction support system according to the present invention, the sale power receiving right information is information including a sale unit price set for the sale receiving power in addition to the sale receiving power. , The purchase power reception right information is information including a purchase unit price set for the purchase target power reception amount in addition to the purchase target power reception amount,

An embodiment of a power receiving transaction support system according to the present invention will be described with reference to the drawings.
FIG. 1 shows a plurality of power receivers using a power line 4 operated by an electric power company from a power supply unit 4 operated by a specific scale electric power provider (hereinafter referred to as PPS (Power Producer and Supplier)) 1. It is explanatory drawing which showed the mode of the electric power business which entrusts electric power to 10.

  The power receiving right transaction support system 30 is configured by a computer operated by the PPS 1 and will be described in detail later. The power receiving right transaction supporting system 30 is a transaction target between the power receivers 10 or between the power receivers 10 and the PPS 1 in a specific period such as unit time. It is configured to support a transaction of a power reception right that is a right to receive the amount of power received. The power receiving right transaction support system 30 may be operated by a third party other than the PPS 1.

  Each of the power receivers 10 includes a power consuming unit 29 such as an electric lamp or an electric device that consumes power in accordance with the life of the power receiver 10. Power consumption during a specific period of time, such as daytime, a specific day of the week, a specific day of a month, a specific month of a year, etc. A specific power consumption unit having a specific power consumption unit 29a that does not consume or consumes power in other periods without consuming power in the specific period, and a power consumption unit 29b other than the specific power consumption unit 29a There are the retained power receiver 11 and the power generation facility retained power receiver 12 having the power generation facility 24 such as a cogeneration system capable of generating a part of the power consumption of the power consumption unit 29 by consuming fuel such as city gas. .

Each power receiver 10 concludes a power supply / demand contract with the PPS 1 by determining the contract power reception amount according to the maximum power reception amount predicted from the total of the maximum power consumption of the power consumption unit 29 and the like. doing.
Therefore, each power receiver 10 receives power in a form in which the contract received power amount is set as the maximum allowable received power amount, and the received power amount from the transmission line 2 is limited to the maximum allowable received power amount or less.
The maximum allowable power reception amount and the contract power reception amount may be constant values, but may be values that change every unit time or the like.

  Each power receiver 10 side is provided with a power receiver side terminal 13 composed of a computer configured to be able to communicate with the PPS 1 side, for example, a power receiving transaction support system 30 via a communication line 40 such as the Internet network. Yes. The power receiver side terminal 13 acquires the power reception amount from the power transmission line 2 of the power receiver 10 measured by the power reception amount measuring device 15 provided on the power receiver 10 side for each unit time, and the power reception amount is obtained on the PPS1 side. For example, the power receiving transaction support system 30 can recognize the amount of power received by each power receiver 10 per unit time.

  Next, a detailed configuration of the power reception right transaction support system 30 and the power receiver side terminal 13 for supporting the transaction of the power reception right that is the right to receive the power of the transaction target power reception amount in the specific period between the power receivers 10 Will be described.

  First, the power reception right transaction support system 30 executes predetermined computer software, thereby selling power reception right information acquisition means 31, purchase power reception right information acquisition means 32, transaction means 35, transaction target power reception right information output means 36, which will be described later. Furthermore, it is configured to function as a sales side curve deriving unit 33, a purchase side curve deriving unit 34, a power receiving right fee calculating unit 37, and an excess power receiving amount acquiring unit 38. On the other hand, the power receiver side terminal 13 is also configured to function as a maximum allowable power receiving amount adjusting unit 20 described later by executing predetermined computer software.

The power receiver side terminal 13 on the power receiver 10 side who desires to sell the power receiving right in the specific period specified by the power receiver 10 or in the specific period specified by the PPS 1 side is in the state where the power receiving right transaction support system 30 is accessed. It is configured to input a sale target received amount and a sale unit price set for the sale target received amount to be sold in a period, and transmit them to the power receiving transaction support system 30 side.
The power receiving amount to be sold can be arbitrarily determined by the power receiver 10 as the seller, but can also be determined as follows.

  For example, as a specific power consuming unit 29a that does not consume power during a specific period, the seller is a specific power consuming apparatus possessed power receiver 11, and for reasons such as air conditioning equipment or maintenance that is stopped during the specific period In the case of possessing a device or the like whose operation is stopped during a specific period, the received power received for sale may be set to be equal to or less than the maximum power consumption according to the maximum power consumption of the specific power consumption unit 29a. it can.

In addition, regarding the generation of the sale power receiving right information in this specific period, the specific power consuming equipment possessed receiver 11 who is the seller may set the specific power consumption unit 29a to be in a non-permitted state and the maximum power thereof. Although it may be performed with reference to the consumption amount, the power reception right information may be automatically generated by the power receiver terminal 13 or the power reception right transaction support system 30.
For example, referring to the power consumption per unit time of the specific power consumption unit 29a, a specific period during which the power consumption of the specific power consumption unit 29a is almost absent and the power reception may be stopped in a non-permitted state is derived. The sale power receiving right information may be automatically generated in a form in which an amount obtained by subtracting a margin from the maximum power consumption of the specific power consumption unit 29a stored in advance during the specific period is determined as the sale target power reception amount. it can. Further, the selling unit price can be determined based on the risk received by the specific power consuming equipment possessed power receiver 11 as the seller by setting the power reception of the specific power consuming unit 29a to the non-permitted state.

  In addition, with respect to the specific power consuming equipment possessed power receiver 11 that possesses a plurality of specific power consuming units 29a as described above, at least one specific power is determined with reference to the power consumption per unit time of each specific power consuming unit 29a. It is possible to automatically generate sold power reception right information for a specific period during which the power consumption of the power consuming unit 29a may be in a non-permitted state.

  And when the sale of the power reception right is established, the specific power consuming equipment possessed power receiving which is the seller is opened by opening the interrupter 27 capable of interrupting the power reception of the specific power consumption unit 29a in the specific period. A power receiving right which is a right to receive the power of the transaction target received amount by adjusting the maximum allowable power received amount for the specified period of the person 11 to the lower side of the transaction target received amount determined to be at least the sale target received amount or less. The power can be reliably delivered to the power receiver 10 that is the purchaser.

  Further, if the seller is the power generation facility holding power receiver 12 and there is a surplus in the amount of power generated by the power generation facility 24 in the specific period, or the power generation facility 24 is stopped in the specific period, the power generation Depending on the power generation increase amount that can be increased with respect to the power generation amount of the facility 24, the sale target power reception amount can be set to be equal to or less than the power generation increase amount.

In addition, regarding the generation of sale power receiving right information in this specific period, the power generation facility holding power receiver 12 that is the seller may increase the power generation amount of the power generation facility 24 by itself, and the power generation amount that can be increased. However, the power receiving terminal 13 and the power receiving transaction support system 30 can automatically generate the sale power receiving right information.
For example, referring to the power generation amount of the power generation facility 24 per unit time, a specific period in which the power generation facility 24 is stopped or the power generation amount is sufficient is derived, and the power generation amount of the power generation facility 24 in the specific period is derived. The sale power right information can be automatically generated in a form in which the increaseable amount is determined as the sale target power reception amount. In addition, the unit sales price can be automatically determined based on the power generation cost by storing the power generation cost per power generation amount of the power generation facility 24 in advance.

  Further, with respect to the power generation facility holding power receiver 12 who owns a plurality of power generation facilities 24 as described above, at least one power generation facility 24 is stopped with reference to the power generation amount of each power generation facility 24 per unit time. Alternatively, it is possible to automatically generate sale power reception right information for a specific period in which there is a margin in the amount of power generation.

  If the sale of the power reception right is established, the power generation facility 24 is sold by increasing the power generation amount of the power generation facility 24 by at least the transaction target power reception amount determined to be equal to or less than the sales target power reception amount in the specific period. Receiving power 10 that is the right to receive the power of the transaction target power reception amount by adjusting the maximum allowable power reception amount of the power generation facility possession power receiver 12 for a specific period to the side of the transaction target power reception amount decrease. It can be reliably delivered to the side.

On the other hand, the power receiver side terminal 13 on the power receiver 10 side who desires to purchase the power reception right in the same specific period is in the state of accessing the power reception right transaction support system 30 and purchased in the power reception right to be purchased in the specific period. The power reception amount and the purchase unit price set for the purchase target power reception amount are input and transmitted to the power reception right transaction support system 30 side.
Note that the power receiving amount 10 to be purchased can be arbitrarily determined by the power receiver 10 as the purchaser, but can also be determined as follows.

  For example, the purchaser is the specific power consuming device possessing power receiver 11 and, as the specific power consuming unit 29a that consumes power in the specific period, the air conditioner that is operated in the specific period or for other reasons only during the specific period When a device to be operated is held, the purchase target power reception amount can be set to be equal to or greater than the maximum power consumption amount according to the maximum power consumption amount of the specific power consumption unit 29a.

In addition, regarding the generation of purchase power receiving right information in this specific period, the specific power consuming equipment possessed receiver 11 who is the purchaser himself / herself should allow the specific power consumption unit 29a to receive power and the maximum power consumption amount thereof. However, the power receiving terminal 13 and the power receiving transaction support system 30 can automatically generate the sale power receiving right information.
For example, with reference to the power consumption amount per unit time of the specific power consumption unit 29a, a specific period in which the power consumption amount of the specific power consumption unit 29a exists and should be allowed to receive power is derived. Purchase power reception right information can be automatically generated in such a manner that an amount obtained by adding a margin to the maximum power consumption of the specific power consumption unit 29a stored in advance is determined as the purchase target power reception amount. Further, the purchase unit price can be determined based on profits and the like that can be obtained by the specific power consuming equipment possessed power receiver 11 who is the purchaser by allowing the specific power consumption unit 29a to receive power.

  In addition, with respect to the specific power consuming equipment possessed power receiver 11 that possesses a plurality of specific power consuming units 29a as described above, at least one specific power is determined with reference to the power consumption per unit time of each specific power consuming unit 29a. Purchase power reception right information for a specific period in which the power consumption unit 29a should be allowed to receive power can be automatically generated.

  Then, when the purchase of the power reception right is established, the specific power consuming equipment possessed power reception that is the purchaser is made by connecting the interrupter 27 capable of interrupting the power reception of the specific power consumption unit 29a in the specific period. The power receiving right which is the right to receive the power of the transaction target power reception amount by adjusting the maximum allowable power reception amount in the specific period of the person 11 to the increase side of the transaction target power reception amount determined to be at least equal to the purchase target power reception amount It can be reliably received from the power receiver 10 which is a seller.

  In addition, when the purchaser is the power generation facility holding power receiver 12 and the power generation amount of the power generation facility 24 is not enough in the specific period, or the power generation facility 24 is stopped in the specific period for reasons such as maintenance. Depending on the amount of power generation reduction by which the power generation amount of the power generation facility 24 is reduced, the purchase target power reception amount can be set to be equal to or greater than the amount of power generation reduction.

In addition, regarding the generation of purchase power receiving right information in this specific period, refer to the specific period in which the power generation facility holding power receiver 12 as the purchaser should reduce the power generation amount of the power generation facility 24 and the power generation amount corresponding to the decrease. Although it may be performed, the power receiving terminal 13 and the power receiving right transaction support system 30 may be configured to automatically generate the purchase power receiving right information.
For example, referring to the power generation amount of the power generation facility 24 per unit time, a specific period in which the power generation facility 24 has no margin and the power reception amount of the power receiver 10 may exceed the maximum allowable power reception amount is derived, or The maintenance period of the registered power generation facility 24 is derived as a specific period during which the power generation facility 24 should be stopped, and the amount of decrease in the power generation amount of the power generation facility 24 is determined as the purchase target power reception amount during the specific period. Rights information can be generated automatically. In addition, the purchase unit price is determined in advance based on the power generation cost per power generation amount of the power generation facility 24 and automatically based on the power generation cost or the risk of receiving power exceeding the maximum allowable power reception amount. Can do.

Next, the transaction means 35 in which the power reception right transaction support system 30 functions is based on the sale power reception right information and the purchase power reception right information, and the transaction target power reception amount and the transaction target power reception in the power reception right to actually trade. The transaction unit 35 is configured to determine the transaction unit price of the quantity, and the transaction means 35 establishes the transaction of the power reception right between the power receiver 10 as a seller and the power receiver 10 as a purchaser.
A detailed method for establishing a power reception right transaction by the transaction means 35 will be described later.

Next, the transaction target power receiving right information output means 36 on which the power receiving right transaction support system 30 functions is a seller of the transaction target power receiving right information including at least the above described transaction target power receiving amount determined by the transaction means 35. It is configured to output in a form to be transmitted to the respective power receiver side terminals 13 on the power receiver 10 side and the power receiver 10 side which is the purchaser.
Then, in the power receiver 10 who is a seller, the power receiving right information is received by the power receiver side terminal 13 so that the power receiving right can be sold and the maximum allowable power receiving amount in a specific period can be obtained. Power is received in a form adjusted to the transaction target power receiving amount decrease side, while the power receiver 10 who is the purchaser also purchases the power receiving right by receiving the power receiving power information on the power receiving side terminal 13 Knowing that this has been done, adjusting the maximum allowable power reception amount for the specified period to the increase in the amount of power received by the transaction, the delivery of the power reception right from the seller to the purchaser is executed reliably.

  Next, the power receiver 10 side, which is a seller or purchaser, receives the transaction target power right information output from the transaction target power right information output means 36 and automatically receives a specific period for the power receiver 10. The maximum allowable power receiving amount adjusting means 20 for adjusting the maximum allowable power receiving amount for the transaction target power receiving amount is provided, and the detailed configuration will be described.

  The power receiver-side terminal 13 on the specific power consuming device possessing power receiver 11 side executes a predetermined computer program to switch the power reception availability state of the specific power consumption unit 29a as the maximum allowable power reception amount adjusting unit 20. It is configured to function as power reception availability state switching means 21 that adjusts the maximum allowable power reception amount.

  That is, as described above, the power reception availability state switching unit 21 in which the power receiver side terminal 13 functions, when the specific power consuming equipment possessed power receiver 11 is a power sales right seller, outputs the transaction target power reception right information. In response to the transaction target power receiving right information output from the means 36, the interrupter 27 capable of interrupting the power reception of the specific power consumption unit 29a in the specific period is opened and the power reception of the specific power consumption unit 29a is disabled. Thus, the maximum allowable power reception amount in the specific period of the specific power consumption device possessed power receiver 11 is adjusted to at least a reduction side corresponding to the transaction target power reception amount, while the specific power consumption device possession power receiver 11 is the purchaser of the power reception right. In this case, the transaction power receiving right information output from the transaction power receiving right information output means 36 is received, and the interrupter 27 capable of interrupting the power reception of the specific power consumption unit 29a in the specific period is connected. The specific power consumption unit 29a is allowed to receive power as a state, and is configured to adjust the maximum allowable power reception amount in the specific period of the specific power consumption device possessed power receiver 11 to at least the increase side corresponding to the transaction target power reception amount. Yes.

  Further, the power receiver side terminal 13 on the power generation facility holding power receiver 12 side executes a predetermined computer program, thereby adjusting the power generation amount of the power generation facility 24 as the maximum allowable power reception amount adjusting means 20 and performing the maximum allowable power reception. It is comprised so that it may function as the power generation equipment control means 22 which adjusts quantity.

  That is, as described above, the power generation facility control unit 22 that the power receiver side terminal 13 functions is obtained from the transaction target power reception right information output unit 36 when the power generation facility possession power receiver 12 is a seller of the power reception right. In response to the output power receiving right information of the transaction target, the power generation capacity of the power generation facility 24 is increased by at least the power reception amount for the transaction target in the specific period, so that at least the maximum allowable power reception amount in the specific period of the power generation facility holding power receiver 12 is traded. In the case where the power receiving facility 12 is a purchaser of the power receiving right, the transaction target power receiving right information output from the transaction target power receiving information output means 36 is received. Thus, by reducing the power generation amount of the power generation facility 24 at least by the amount of power received for the transaction in the specific period, at least the maximum allowable power reception amount in the specific period of the power generation facility-owned power receiver 12 is set. It is configured to adjust for the pulling target power receiving amount increase side.

The power reception right fee calculation means 37 for functioning the power reception right transaction support system 30 is configured to calculate a power reception right fee paid from the purchaser who purchased the power reception right to the seller who sold the power reception right. The power reception right fee calculated in the above is notified to each power receiver 10 side which is the seller and purchaser through the power receiver side terminal 13 or the like, and the power receiver 10 who is the purchaser sells the power right fee based on the notification. The power receiving right fee is settled by transferring money online to the power receiver 10 side.
Such settlement may be performed by adding or subtracting the power reception fee to the power fee received by the PPS 1 from each power receiver 10.

Further, the power reception right fee calculation means 37 sets the excess power reception amount actually received within the transaction target power reception amount in the power reception right purchased by the power receiver 10 as the purchaser in a specific period with respect to the power reception fee. An excess fee calculated accordingly is added.
The excess power reception amount is acquired by the excess power reception amount acquisition unit 38 in which the power reception right transaction support system 30 functions. Specifically, the excess power reception amount acquisition unit 38 refers to the power reception amount per unit time measured by the power reception amount measuring instrument 15 on the power receiver 10 side, which is the purchaser, and the normal amount of the power receiver 10 from the power reception amount. The amount obtained by subtracting the contract power reception amount that is the maximum allowable power reception amount is acquired as the excess power reception amount. In addition, based on the estimated amount of power received in the specified period predicted from the purchaser's past amount of received power, the charge calculated according to the amount of actual power received in the purchaser's specified period is also used as the above power reception fee You may add.

  Furthermore, based on the estimated amount of power received in the specified period predicted from the past amount of power received by the seller, the charge calculated according to the amount of actual power received in the specific period of the seller is less than You may add.

  Next, a detailed method for establishing a power reception right transaction by the transaction means 35 will be described.

  First, the selling-side curve deriving means 33 for functioning the power receiving right transaction support system 30 prioritizes the sale of the power receiving right with a low selling unit price among a plurality of pieces of power receiving right information acquired by the power receiving right information acquiring means 31. The sales-side curve indicating the relationship between the transaction unit received amount and the transaction target received amount as the integrated amount of the sale target received amount set to the sale unit price equal to or lower than the transaction unit price is calculated. ing.

  That is, as shown in FIG. 2, the selling-side curve deriving means 33 adds a plurality of sales in a form in which the sales target power received is set in ascending order of the sales unit price from the sales target power received with the minimum selling unit price set. Aggregate the power reception right information and generate a selling-side curve. In other words, the sales-side curve generated in this way increases the sales unit price as the sales target power reception amount increases.

  Note that in FIG. 2, S1 is the seller who entered the power-receiving right information with ES1 as the sales target power receiving amount in the sales power-righting information in which PS1 with the lowest selling unit price is designated, and the selling price is the second lowest. The sale target in the sale power right information with PS2 designated as the sale target power received in the sale power right information with ES2 as the sale target power received by the sale power right information designated as PS2 The seller who entered the power reception right information with the amount of power received as ES3 is S3, and the power reception right information was input with ES4 as the amount of power received for sale in the sale power reception right information for which the PS4 with the fourth lowest selling unit price was specified. The seller is S4.

  On the other hand, the purchase-side curve deriving unit 34 in which the power-receiving-right transaction support system 30 functions gives priority to the purchase of the power-receiving right having a high purchase unit price among the plurality of power-receiving power information acquired by the power-receiving-right information acquiring unit 32. Aggregating and deriving a purchase-side curve indicating the relationship between the transaction target power received amount as an integrated amount of the purchase target power received amount set to the transaction unit price below the transaction unit price. Yes.

  That is, as shown in FIG. 3, the purchase-side curve deriving means 34 adds a plurality of purchase purchase amounts in a form in which purchase purchase amounts are set in descending order of purchase purchase amounts from purchase purchase receipt amounts set to the maximum purchase unit price. Aggregate power reception right information to generate a purchase-side curve. That is, the purchase side curve generated in this way has a purchase unit price that decreases as the purchase target power reception amount increases.

  In FIG. 3, the purchase target received amount in the purchase power right information in which PB1 having the highest purchase unit price is designated is EB1, and the purchaser who inputs the power right information is B1, and the purchase unit price is the second highest. The purchase target power received in the purchase power right information designated by PB2 is designated as EB2, and the purchaser who inputs the power right information is designated as B2, and the purchase target in the purchase power right information designated by PB3 having the third highest purchase unit price. The purchaser who entered the power reception right information with EB3 as the amount of power received is B3, and the power reception right information is input with EB4 as the purchase target power reception amount in the purchase power reception right information in which the PB4 having the fourth highest purchase unit price is specified. The purchaser is B4.

And the transaction means 35 specified the sale unit price below the transaction unit price in the form of determining the transaction unit price and the transaction target power reception amount based on the equilibrium point between the sale side curve and the purchase side curve derived as described above. The power receiving right transaction is established between the seller and the purchaser who has specified a purchase unit price equal to or higher than the transaction unit price.
Specifically, as shown in FIG. 4, the transaction means 35 superimposes the sales side curve and the purchase side curve derived as described above, and derives the intersecting portion as an equilibrium point. Then, the total amount of received power ES1 to be sold in the sold power of the seller S1 and the sold power of the seller S2 so that the transaction of the received power E by the transaction unit price P is established. For the entire amount of power received ES2 subject to sale in the right, the sale price determined by the seller S1 and S2 at the transaction unit price P1 and the transaction unit price P equal to or higher than PS2, and the purchase target of the purchase power of the purchaser B1 The purchaser of the total amount of the received power EB1, the total amount of the received power EB2 for purchase in the purchase power of the purchaser B2, and a part below the equilibrium point of the purchased power received EB3 for the purchase power of the purchaser B3 Decide to sell at the unit price PB1, PB2 and PB3 below the unit price PB1, BB2 and PB3 specified by B1, B2 and B3. The received power amount further determines the transaction unit price.
Then, the transaction target power receiving right information output means 36 includes at least each transaction target power receiving amount on the side of the sellers S1 and S2 and the buyers B1, B2 and B3, which are sellers who have completed the power receiving right transaction. Outputs the target power receiving right information.

  The power receiving transaction support system 30 side and the power receiver side terminal 13 side store various data for mutual communication via the communication line 40. Further, the power receiving transaction support system 30 includes The receiver 10 is identified by receiving the receiver ID from the accessed receiver terminal 13, and various information received from the receiver terminal 13 is stored in association with the receiver ID. Yes.

  In addition, the sale power reception right information acquisition unit 31 and the purchase power reception right information acquisition unit 32 of the power reception right transaction support system 30 do not sequentially acquire the sale power reception right information and the purchase power reception right information from the power receiver side terminal 13. Each information registered in advance can be obtained.

  Furthermore, in the power receiving right transaction support system 30, the PPS 1 can be configured to participate in the power receiving right transaction as a seller or a purchaser.

  That is, when the power supply cost for supplying power from the power supply unit 4 to the power receiver 10 side is relatively high in a specific period such as a time zone in which the total amount of power received by each power receiver 10 is relatively large, When there is no allowance for the power supply amount of the power supply unit 4, the power supply cost for the specific period is purchased, thereby reducing the maximum allowable power supply amount that the power supply unit 4 should supply power and reducing the power supply cost. Can do. In addition, when the PPS 1 purchases the right to receive power in a specific period, the power supply unit 4 supplies the purchase target received power corresponding to the adjustment amount to the lower side of the maximum allowable power supply and the power of the purchase target received power. When the power purchase right transaction is established by inputting the purchase unit price set below the power supply cost at the time of supply by the unit 4 to the power reception right transaction support system 30 side as purchase power reception right information, PPS1 The power supply cost on the side can be reduced.

On the other hand, when the power supply cost for supplying power from the power supply unit 4 to the power receiver 10 side is relatively low in a specific period such as a time zone in which the total amount of power received by each power receiver 10 is relatively small, When the power supply amount of the power supply unit 4 has a margin, the maximum allowable power supply amount to be supplied by the power supply unit 4 is increased by selling the power reception right in the specific period, and the profit from the sale of the power reception right Thus, the power supply cost can be reduced. Further, when the PPS 1 sells the right to receive power in a specific period, it supplies power to be sold corresponding to the adjustment amount to the increase side of the maximum allowable power supply amount of the power supply unit 4 and the power of the power received by the sale. The unit price of sale set above the power supply cost supplied by the unit 4 is input to the power receiving right transaction support system 30 side as selling power receiving right information, so that when the power receiving right transaction is established, PPS1 The power supply cost on the side can be reduced.
Note that when the PPS 1 participates in the power receiving right transaction as a seller or a purchaser as described above, the power receiving transaction support system 30 generates the selling power receiving right information and the purchased power receiving right information. The power supply information regarding the actual power supply amount, the maximum allowable power supply amount, the power supply cost, and the like in 4 is stored in advance, and the generation and input of the sale power purchase right information and purchase power supply right information specified by the PPS 1 are automatically used by using the power supply information. You may comprise so that it may carry out.
In addition, PPS1 procures power that can cover the expected power reception amount of the power receiver 10 on the day before power is supplied to each power receiver 10, and the power supply cost on the PPS 1 side is optimized (for example, minimized). In addition, when performing a power supply plan for planning a power procurement form such as determining a generator to be started and its output, etc., it is possible to further increase the power supply cost by taking into account the purchase and sale of power reception rights of the power receiver 10. Optimization can be achieved. That is, when the power procurement cost by the power generation by one's own generator or the purchase of power from other markets is relatively high, the power receiving right of the power receiver 10 is purchased at a cost lower than the power procurement cost. When the power procurement cost by power generation by one's own generator or the purchase of power from other markets is relatively low, the power supply is sold by selling the power reception right to the power receiver 10 at a higher cost than the power procurement cost. Cost can be further reduced.

In the above-described embodiment, the transaction unit 35 determines the transaction unit price and transaction target power reception based on the equilibrium point between the sale side curve derived by the sale side curve deriving unit 33 and the purchase side curve derived by the purchaser side curve deriving unit 34. Although the power receiving right transaction is established in the form of determining the amount, it may be configured as follows.
That is, the transaction means 35 is divided into a seller and a purchaser who have acquired the sale power right information and the purchase power right information satisfying the condition that the sale power reception amount is equal to or greater than the purchase power receipt amount and the sale unit price is equal to or less than the purchase unit price. The transaction target received amount is determined as the purchase target received amount, and the transaction unit price is determined as the sale unit price, and the transaction of the power reception right is established between the seller and the purchaser. be able to.
In addition, in the case of conducting a power reception right transaction between one seller and one purchaser in this way, the seller or purchaser is made to browse the power reception right information designated by the other side, and the power reception The power receiving right transaction may be established in a so-called auction format in which the power receiving right information is input so as to satisfy the above-mentioned conditions for the right information.

  Moreover, in the said embodiment, the power receiver 10 who is the seller who sold the power reception right makes the power reception of the specific power consumption part 29a in a specific period, increases the electric power generation amount of the power generation equipment 24, etc. Then, by adjusting the maximum allowable amount of power received by the power receiver 10 to the transaction target power receiving amount lowering side, the power received was transferred to the purchaser and the price was received, but the power received was sold separately. The power receiver 10 as a seller may be able to receive power exceeding the maximum allowable power reception amount that has been reduced in a specific period by paying a penalty fee for default of the debt to which the power is to be delivered. . In addition, in the case where the default of the power to be received by the power receiver 10 that is the seller has occurred, the notification from the power receiver 10 that is the seller or the power reception of the power receiver 10 is received. In response to notification from the PPS 1 side that the amount has exceeded the maximum allowable power reception amount, the seller will take a penalty to cancel the increase in the maximum power reception amount of the power receiver 10 that is the purchaser. You may make it pay to the purchaser side, but PPS1 side does not cancel the increase of the amount of the transaction target received amount of the purchased power amount 10 by the purchaser due to the default of the seller who is the seller. The necessary power may be procured and the seller may pay a penalty fee to the PPS 1 side.
