SYSTEM AND METHOD FOR INTERMEDIATING ELECTRIC POWER TRANSACTION INCLUDING LOGIC OF DISTRIBUTION OF POWER}

The present invention relates to a technology for providing a power trading platform between a power producer and a power buyer, and more particularly, when one or more power producers and one or more power buyers trade power, power providing logic for distributing power between trading parties It relates to a system for providing a trading intermediary platform and a method for providing a power trading intermediary platform.

Industrial complexes are considered as strong candidates among microgrid destinations because many manufacturing-type companies that consume electricity are concentrated.

The RE100 (Renewable Energy 100) campaign refers to a campaign to cover 100% of the electricity used by a company with renewable energy. The RE100 campaign was first introduced in 2014 by The Climate Group, a multinational non-profit organization, and more than 200 companies worldwide are participating, and global companies such as Apple, Google, GM, BMW, Coca-Cola and Ikea are here. Included.

The companies participating in the RE100 campaign are mostly American and European companies, and there are Asian companies such as Japan, China, and India, but there are no Korean companies yet. If the target achievement year for each company is slightly different, 2050 is suggested at the latest.

As environmental regulations in each country get stronger and consumers are concerned about climate change, RE100 goes beyond a promotional strategy to improve corporate image. is occurring

In order to secure renewable energy, companies can pay the green rate system, build new and renewable power generation facilities, or purchase renewable energy by obtaining and proving a renewable energy use certificate.

Large companies and mid-sized companies can participate in RE100 relatively easily by building or purchasing facilities, but it is not easy for small and medium-sized companies that are doing parts or subcontracting to global companies participating in RE100. RE100 of small and medium-sized enterprises through the provision of renewable distributed power generation and energy saving programs installed in industrial complexes in line with the fact that these companies are mainly distributed in industrial complexes and the environment of smart industrial complexes and microgrids of industrial complexes. There is a need for a method to reduce the cost and burden of procedures required to secure a certificate.

A third party power supply agreement (PPA) is presented as one way to achieve the RE100 campaign. A power supply contract (PPA) refers to a contract made when a power producer sells electricity produced through renewable energy generation to a power company. In addition, the third party power supply contract (PPA) refers to a contract in which the power produced by the power producer is directly sold to a power purchaser. When a plurality of transaction parties are included in the electricity transaction, a discussion is emerging on how to distribute electricity between the transaction parties.

However, this is an example, and the type of the power producer terminal 110 and/or the power purchaser terminal 120 may be variously modified.

The power producer terminal 110 and/or the power purchaser terminal 120 may transmit a buy order and a sell order for power purchase and/or sale to the power transaction intermediary platform providing system 130 . The sell order may include a desired sales volume, a desired sale price and/or a desired sale time, and the buy order may include a desired purchase amount, a desired purchase price and/or a desired purchase time. The price may mean a price per unit price of power. For example, the price may mean a price per 1 kW.

In another embodiment, the power producer terminal 110 and/or the power purchaser terminal 120 receives the power transaction participation message, and purchases and/or purchases electricity to the power transaction intermediary platform providing system 130 . It can deliver orders and sell orders. That is, the plurality of power producer terminals 110 may bid to sell electricity with the power trading intermediary platform providing system 130 , and the plurality of power purchaser terminals 120 may use the power trading intermediary platform providing system 130 . You can bid to buy electricity.

The power trading intermediary platform providing system 130 forms a power trading market between the power producer terminal 110 and the power purchaser terminal 120 based on the bidding participation information of the power producer terminal 110 participating in the bidding. When forming the electricity trading market, the transaction decision between the electricity producer terminal 110 and the electricity purchaser terminal 120 is based on the offer price offered at the time of bidding, and the amount of electricity (transaction volume) can be distributed based on the offer price.

The power transaction intermediary platform providing system 130 receives and stores the sell order of the power producer terminal 110 and/or the buy order of the power purchaser terminal 120 , or the contract conclusion and contract progress with the power company 140 . The transceiver 131 configured to communicate the status, the intermediary unit 133 configured to mediate the sell order of the power producer and the buy order of the power buyer, the distribution unit 135 configured to monitor the progress of the concluded power transaction, and the transaction It may include a settlement unit 137 to settle the price.

The transceiver 131 may receive and store a sell order and/or a buy order from the power producer terminal 110 and/or the power purchaser terminal 120 ( S110 ). In addition, the transceiver 131 may transmit contract conclusion details and contract progress status to the power company 140 . The amount of power for which the contract is concluded may be referred to as a contract transaction volume. Also, the amount of power actually transmitted by the power producer to the power purchaser may be referred to as an actual power transmission amount. The contract conclusion may include a power producer, a power purchaser, a contract transaction volume, a price, and/or a power generation capacity of the power producer. The contract progress status may include a contract transaction amount, a power generation capacity of a power producer, and/or an actual transmission power amount.

In addition, the transceiver 131 provides the power company 140 with the power producer's application and/or contract signing document, the power purchaser's application and/or contract signing document, the power producer's actual power transmission amount information and/or It is possible to transmit and receive information about the payment result of the power purchaser.

The intermediary unit 133 receives a bid proposal from the power producer terminal 110 and/or the power purchaser terminal 120 and serves as an intermediary between the power producer terminal 110 and the power purchaser terminal 120 . According to an embodiment of the present invention, the intermediary unit 133 may receive a sell order and/or a buy order stored in the transceiver 131 .

The intermediary unit 133 may mediate a sell order and a buy order in various ways. For example, the intermediary unit 133 may mediate a sell order and a buy order using the principle of price priority (S120).

The intermediary unit 133 may notify the successful bid power purchaser terminal 120 and the power producer terminal 110 that the transaction has been established. Thereafter, the power purchaser corresponding to the power purchaser terminal 120 may pay a power price to the power producer corresponding to the power producer terminal 110 , and the power producer may transmit power to the power purchaser. The power producer may transmit a certain amount of power to the power purchaser on a specified date. The date and the amount of electricity may be included in the bidding participation information. In addition, the electricity price may also be included in the bidding participation information. The transaction price may be calculated by multiplying the amount of electricity and the price of electricity.

The intermediary unit 133 may enter into a contract so that the desired sales volume of the power producer is equal to or greater than the size of the power generation capacity of the power producer. For example, the power generation capacity may be a maximum power generation capacity of a fuel cell and/or solar power of the power producer.

In addition, the intermediary unit 133 may change the transaction time. For example, when the transaction time is concentrated in a specific time period (eg, 12:00 to 14:00), it may not be easy for a power producer to transmit power to a power purchaser. Accordingly, the intermediary unit 133 may change the transaction time to a time period in which power consumption is low.

The distribution unit 135 may be configured to distribute power between a contracted power producer and a power purchaser (S130). The distribution unit 135 may distribute power based on the contract transaction amount and the amount of power generated by the power producer. The distribution unit 135 may control the power producer not to transmit more than contract power. In addition, when the power producer produces less than the sum of the contract power, the distribution unit 135 distributes and transmits the sum of the power produced by the power producer according to the contract weight of each power purchaser. There is (S131). When there are a plurality of power producers, the power distribution amount of each power producer may be determined independently of each other. Also, when there are a plurality of power purchasers, the power distribution amount may be determined independently of each power purchaser.

According to an embodiment of the present invention, when a plurality of power producers and a plurality of power buyers are intermediary, the contract weight of the plurality of power producers is calculated first, and then the contract weight of the plurality of power purchasers is calculated to generate power generation The distribution of power can be made. In another embodiment, when a plurality of power producers and a plurality of power buyers are intermediary, the contract weight of the plurality of power buyers is calculated first, and then the contract weight of the plurality of power producers is calculated to distribute the power generated by the power producers This can be done.

The contract weight of the plurality of power purchasers may be determined by proportionally distributing contract transaction amounts of each of the plurality of power purchasers. That is, the contract weight of each power purchaser may be determined as in [Equation 1].

[Equation 1]

Here, W _c,k represents the contract weight of the k-th power purchaser, and P _c,k represents the contract transaction volume of the k-th power purchaser. The power purchaser's contract transaction volume in the denominator of Equation 1 may be calculated including all of the pre-established power purchaser's contract transaction volume before the power transaction is concluded. That is, the contract weight may be updated whenever a new contract is concluded.

Also, when the actual power generation amount of the power producer is greater than the contract power amount, the distribution unit 135 may control the producer to transmit only the contract power amount. Therefore, the amount of power actually transmitted to each power purchaser can be calculated as in [Equation 2].

[Equation 2]

Here, RP _c,k means the actual power transmission amount received by the k-th power purchaser, W _c,k represents the contract weight of the k-th power purchaser, PP _p means the actual power generation amount of the power producer, P _{c ,k} represents the contract transaction volume of the kth power purchaser.

The distribution unit 135 may compare the contract transaction amount and the actual power transmission amount of each of one or more power producers (S133). In addition, when the contract transaction amount of the power purchaser is greater than the actual power transmission amount, the power company 140 may transmit power equal to the difference between the contract transaction amount and the actual power transmission amount to the power purchaser ( S135 ). That is, the amount of power transmitted by the power company 140 may be expressed by [Equation 3].

[Equation 3]

Here, RP _kepco,k represents the amount of power transmitted by the power company 140 to the k-th power buyer, P _c,k represents the contract transaction volume of the k-th power buyer, and W _c,k represents the contract of the k-th power buyer. It represents the specific gravity, PP _p means the actual power generation amount of the power producer, and RP _c,k represents the actual power transmission amount transmitted by the k-th power purchaser.

For example, it is assumed that electricity purchaser A and electricity purchaser B trade electricity with electricity producer C. For example, when A's contract volume is 1000kW and B's contract volume is 2000kW, the ratio of the contract weight between A and B may be set to 1:2. In this case, the sum of the contracted transaction volumes of C is 3000 kW. Accordingly, when C produces power of 3000 kW or more, the distribution unit 135 may transmit 1000 kW to A and distribute 2000 kW to B. In addition, when C produces less than 3000 kW of power, for example, when C produces 2700 kW of power, A may receive 900 kW from C, and B may receive 1800 kW from C. Also, A may receive 100 kW from the power company 140 , and B may receive 200 kW from the power company 140 .

According to another embodiment, another power producer not participating in the transaction may transmit power equal to the difference between the contract transaction amount and the actual power transmission amount to the power purchaser.

In addition, when a plurality of power producers and a single power buyer are intermediary, the contract weight of each of the power producers may be determined by distributing the contract transaction amounts of each of the power producers in proportion. That is, the contract weight of each power producer may be determined as in [Equation 4].

[Equation 4]

Here, W _p,k represents the contract weight of the k-th power producer, and P _p,k represents the contract transaction volume of the k-th power producer.

The contract transaction amount of the power producer in the denominator of [Equation 4] may be calculated including all of the contract transaction volume of the electricity producer that has been established before the power transaction is concluded.

For example, if power producer D and power producer E participate in the same electricity trade, D's contract volume is 1000 kW, and E's contract volume is 3000 kW, the ratio of the contract weight between power producer D and power producer E is 1 :3 can be set.

The contract transaction amount of the power producer in the denominator of [Equation 4] may be calculated including all of the contract transaction volume of the electricity producer that has been established before the power transaction is concluded. That is, the contract weight may be updated whenever a new contract is concluded.

According to an embodiment of the present invention, when a plurality of power producers and a plurality of power buyers are intermediary, the power transaction can be performed by calculating the contract weights of the plurality of power producers first, and then calculating the contract weights of the plurality of power buyers. have. In another embodiment, when a plurality of power producers and a plurality of power buyers are intermediary, the power transaction may be performed by first calculating the contract weights of the plurality of power buyers and then calculating the contract weights of the plurality of power producers.

The intermediate unit 133 and/or the distribution unit 135 may be implemented in hardware, firmware, software, or any combination thereof. For example, the intermediate unit 133 and/or the distribution unit 135 may be a computing device such as a workstation computer, a desktop computer, a laptop computer, or a tablet computer. For example, the intermediary unit 133 and/or the distribution unit 135 may include a memory device such as a read only memory (ROM) and a random access memory (RAM), and a processor configured to perform predetermined operations and algorithms, for example For example, it may include a microprocessor, a central processing unit (CPU), a graphics processing unit (GPU), and the like. In addition, the intermediate unit 133 and/or the distribution unit 135 may include a receiver and a transmitter for receiving and transmitting electrical signals.

The settlement unit 137 may receive information on the actual power transmission amount from the power company 140 through the transceiver 131 . Also, the power company 140 may calculate the actual power transmission amount based on the annual power generation amount of the power producer. The settlement unit 137 may transmit the settlement information to the power producer terminal 110 and/or the power purchaser terminal 120 (S140).

5 is a diagram illustrating a relationship between an actual power transmission amount and a contract transaction amount of a power producer according to an embodiment of the present invention. For example, it is assumed that the size of the contract transaction volume in FIG. 5 is P _c . The bar graph means the actual power transmission amount of the power producer, and V1 represents the difference between the size of the first actual power transmission amount (RP _c,1 ) in (a) and the size of the contract transaction amount (P _c ). V2 represents the difference between the size of the third actual power transmission amount (RP _c,3 ) and the size of the contract transaction amount (P _c ) in (c).

1 to 5 together, the contract transaction amount may be set equal to or greater than the sum of the power generation capacities of the power producers. In (a) of FIG. 5 , a difference between the size of the first actual power transmission amount (RP _c,1 ) and the size of the contract transaction amount (P _c ) by V ₁ may occur. Accordingly, in (a), as much power is transmitted as the size (RP _c,1 ) of the first actual power transmission amount, the transaction price can be calculated based on the size (RP _c,1 ) of the first actual power transmission amount. In addition, the power purchaser may receive V ₁ of power from the power company 140 and/or other power producers.

In (b) of FIG. 5 , the size of the contract transaction amount (P _c ) and the size of the second actual power transmission amount (RP _c,2 ) may be the same. Accordingly, the power company 140 does not need to transmit additional power to the power purchaser, and the transaction price may be calculated based on the size of the contract transaction amount (P _c ).

In (c) of FIG. 5 , a difference between the size of the third actual power transmission amount (RP _c,3 ) and the size of the contract transaction amount (P _c ) by V ₂ may occur. Accordingly, in (c), as much power is transmitted as the size of the third actual power transmission amount (RP _{c ,3} ), the transaction price can be calculated based on the size (RP c,3 ) of the third actual power transmission amount. In addition, the power purchaser may receive V ₂ of power from the power company 140 and/or other power producers.
