世界的に太陽光および電気バッテリーなどのような分散発電資源が速い速度で広がっている。家庭あるいは建物単位で分散発電資源の生産電力量が発生する場合、従来は電力会社が消費電力量に応じた電気料金から生産電力量に応じた電気料金を引いた金額に相殺精算処理をした。すなわち、電力販売会社は、所定の課金期間の間電力網から消費者に流入された電力量から、同一期間の間消費者から電力網に流入された電力量だけ差し引きして精算した。 Distributed generation resources such as solar and electric batteries are spreading at a high speed all over the world. When the production power amount of distributed power generation resources is generated in a home or building unit, the electric power company has conventionally performed offsetting settlement processing on the amount of the electricity rate according to the power consumption amount minus the electricity rate according to the production power amount. That is, the power sales company settled by deducting the amount of power flowing from the power grid to the consumer during the predetermined charging period by the amount of power flowing from the power grid to the consumer during the same period.
最近では個人間（Ｐ２Ｐ：Ｐｅｅｒ−ｔｏ−Ｐｅｅｒ）電力取引が許容されているため、個人たちは個人間に相互取引契約を結んで余剰電力を取引することができるが、個人たちが直接に相互間の利益を極大化する取引相手および取引量を算定するには困難がある。 Recently, since P2P (Peer-to-Peer) power trading is allowed, individuals can trade surplus power by making mutual trading contracts with each other, but individuals can directly trade with each other.

図２は、本発明の一実施形態に係る電力取引仲介装置のブロック図である。
本発明の一実施形態に係る電力取引仲介装置２００は、情報取得部２１０、購入量算出部２３０、購入量電気料金算出部２５０および送信部２７０を含む図２における電力取引仲介装置２００は、図１における電力取引仲介装置１１０に対応する。
FIG. 2 is a block diagram of the power transaction intermediary device according to the embodiment of the present invention.
2 includes an information acquisition unit 210, a purchase amount calculation unit 230, a purchase amount electricity charge calculation unit 250, and a transmission unit 270. The power transaction intermediate device 200 in FIG. 1 corresponds to the power transaction intermediary device 110.
情報取得部２１０は、所定のデータベースから複数の加入者各々の所定の課金期間の間の消費電力量および生産電力量を取得する。所定のデータベースは、電力会社、仲介事業者および第三者を含む様々な運営主体によって運営できることは当業者に明らかなことである。 The information acquisition unit 210 acquires, from a predetermined database, the amount of power consumption and the amount of power production of each of a plurality of subscribers during a predetermined charging period. It will be apparent to those skilled in the art that a given database can be operated by various operators, including electric power companies, intermediaries and third parties.
前記消費電力量および前記生産電力量は、宅内に設けられたスマートメータなどの測定装置（図示せず）によって測定され、前記所定のデータベースに記録される。前記測定装置は、所定の課金期間の間、電力網から加入者に流入された電力量である消費電力量と、加入者から電力網に流入された電力量である生産電力量とを測定する。加入者ｉの消費電力量および生産電力量をそれぞれＤｉ、Ｓｉと定義する。 The power consumption amount and the production power amount are measured by a measuring device (not shown) such as a smart meter provided in the house and recorded in the predetermined database. The measuring device measures, during a predetermined charging period, a power consumption amount that is an amount of electric power that has flowed from a power network to a subscriber and a production power amount that is an amount of power that has flowed from a subscriber to the power network. The power consumption and the production power of the subscriber i are defined as D i and S i , respectively.
情報取得部２１０は、前記所定の課金期間が未来の期間を含む場合、前記所定の課金期間の以前課金期間の情報および外部環境情報に基づいて、前記消費電力量および前記生産電力量を推定する。外部環境情報は温度および湿度を含むが、その他の環境変数が外部環境情報に含まれてもよいことは当業者に明らかなことである。前記所定課金期間の間の前記消費電力量が課金額を決定するため、前記所定の課金期間のうち一部期間が到来していない場合、情報取得部２１０は、前記所定の課金期間の以前課金期間の情報および外部環境情報に基づいて、前記消費電力量および前記生産電力量を推定する。 When the predetermined charging period includes a future period, the information acquisition unit 210 estimates the power consumption amount and the production power amount based on the information of the previous charging period of the predetermined charging period and the external environment information. .. Although the external environment information includes temperature and humidity, it will be apparent to those skilled in the art that other environmental variables may be included in the external environment information. Since the amount of power consumption during the predetermined charging period determines the charging amount, if a part of the predetermined charging period has not arrived, the information acquisition unit 210 causes the previous charging of the predetermined charging period. The power consumption amount and the production power amount are estimated based on the period information and the external environment information.
購入量算出部２３０は、前記複数の加入者各々が前記複数の加入者のうち少なくとも一人の加入者から前記消費電力量のうち一部を購入するための購入量を算出する。 The purchase amount calculation unit 230 calculates a purchase amount for each of the plurality of subscribers to purchase a part of the power consumption amount from at least one of the plurality of subscribers.
購入量算出部２３０は、前記複数の加入者各々が前記購入量を通じて節減する電気料金から取引費用を引いた費用の総和が最大になる、前記複数の加入者各々の前記購入量を算出する。本発明の一実施形態に係る購入量算出部２３０は、複数の加入者各々の前記購入量
を数式１によって決定する。購入量算出部２３０は、数式１を満たす、複数の加入者各々の最適な購入量
を算出する。
ただし、
（ここで：
Ｃｋ（Ｄ）：加入者ｋの消費電力量Ｄに対する電気料金関数、
Ｔｋ：加入者ｋの取引費用、
ａｒｇｍｉｎ（ｆ（ｘ））：関数ｆ（ｘ）を最小値に作るためのｘ値を求める関数、
：加入者ｋの購入量、
Ｓｋ：加入者ｋの生産電力量、
Ｄｋ：加入者ｋの消費電力量）
The purchase amount calculation unit 230 calculates the purchase amount of each of the plurality of subscribers, in which the total sum of the costs obtained by subtracting the transaction cost from the electricity bill saved by the plurality of subscribers is the maximum. The purchase amount calculation unit 230 according to an exemplary embodiment of the present invention determines the purchase amount of each of a plurality of subscribers.
Is determined by Equation 1. The purchase amount calculation unit 230 determines the optimum purchase amount for each of the plurality of subscribers, which satisfies Expression 1.
To calculate.
However,
(here:
C k (D): Electricity charge function for the power consumption D of the subscriber k,
T k : transaction cost of subscriber k,
argmin(f(x)): a function for obtaining an x value for making the function f(x) a minimum value,
: Purchase amount of subscriber k,
S k : the amount of electric power produced by the subscriber k,
D k : power consumption of subscriber k)
下記の数式２の分子の部分を参照すれば、数式２の分子の部分は、加入者ｋの消費電力量に応じた電気料金から、加入者ｋの加入者間購入量を除いた消費電力量に応じた電気料金および取引費用を除いた金額であり、加入者ｋが前記購入量を通じて節減する電気料金を意味する。加入者各々の最適購入量は複数の加入者各々が節減する電気料金の総和が最大になるように算出し、数式１はこれを数式で示したものである。数式１は、数式２の固定値Ｃｋ（Ｄｋ）を除き、残りの負数の部分が最小化される式を示したものである。加入者ｋの購入量は他加入者の生産電力量の総和を超えず、複数の加入者の購入量の総和は複数の加入者の生産電力量の総和を越えない。また、加入者ｋの購入量は加入者ｋの消費電力量を越えない。 Referring to the numerator part of the following mathematical formula 2, the numerator part of the mathematical formula 2 is the electric power consumption corresponding to the power consumption amount of the subscriber k, and the power consumption amount excluding the inter-subscriber purchase amount of the subscriber k. It is an amount excluding the electricity charge and transaction cost according to the above, and means the electricity charge saved by the subscriber k through the purchase amount. The optimum purchase amount for each subscriber is calculated so that the total sum of the electric charges saved by each of the plurality of subscribers is maximized, and Equation 1 is a mathematical expression. Formula 1 shows a formula in which the remaining negative number part is minimized except for the fixed value C k (D k ) of Formula 2. The purchase amount of the subscriber k does not exceed the total production power amount of other subscribers, and the total purchase amount of the plurality of subscribers does not exceed the total production power amount of the plurality of subscribers. Moreover, the purchase amount of the subscriber k does not exceed the power consumption of the subscriber k.
前述したように、前記所定の課金期間が未来の期間を含めて、情報取得部２１０が前記消費電力量および前記生産電力量を推定した場合、Ｃｋ（Ｄ）関数は、推定された消費電力量に基づいて電力価格を算出する。 As described above, when the information acquisition unit 210 estimates the power consumption amount and the produced power amount including the future period of the predetermined charging period, the C k (D) function calculates the estimated power consumption. Calculate the electricity price based on the quantity.
