The settlement settlement DB 204 may include information recording the transaction status of the price for energy according to the futures transaction. The settlement settlement DB 204 may be managed separately by retail settlement settlement or wholesale settlement settlement for energy.

3 is a diagram illustrating the direction of energy between a renewable power plant, an energy transaction server, and a power generation/intermediary operator device according to the form of a renewable power plant according to an embodiment of the present invention.

Referring to FIG. 3 , the energy trading system 100 may indicate the direction of energy to an energy supply entity, an energy consumption entity, and a connection entity on a marketplace service according to the type of a renewable power plant.

The renewable power plant is a resource responsible for only the main body of production in the energy transaction, and may be operated and connected in one direction to deliver the energy produced to the power generation/intermediary operator devices 102 and 103 .

Renewable power plant + Energy Storage System (ESS) and energy prosumer are resources that are responsible for production and consumption in energy transaction, and transmit and receive energy produced by power generation/intermediary operator devices 102 and 103 It can be operated and connected in both directions.

The power generation/intermediation operator devices 102 and 103 are connected to an energy transaction server to use a marketplace service, and may operate as a subject that actually exchanges energy transaction data.

4 is a block diagram of an energy trading system that provides a microgrid platform according to an embodiment of the present invention.

Referring to FIG. 4 , the energy transaction server 101 may operate the microgrid platform 301 . The microgrid platform 301 may be formed of a Building Energy Management System (BEMS), a Community Energy Management System (CEMS), an Energy Servic Company (ESCO), a Factory Energy Management System (FEMS), or the like.

The microgrid platform 301 may include a renewable energy trading platform 201 that provides a marketplace service 202 . In other words, the energy trading server 101 may include a renewable energy trading platform 201 capable of providing the marketplace service 202 on the microgrid platform 301 .

The power generation/intermediary operator devices 102 and 103 may generate power and supply it to the micro-grid 120 , or may receive power from the micro-grid 120 .

Here, the use of the microgrid platform 301 can be said to be a structure in which the energy management aspect within a single microgrid is reinforced from the form in which it was independently operated by the business model for each power generation/intermediary operator of FIG. 3 .

5 is a diagram for explaining an operation of performing an energy transaction capable of production and demand matching between microgrid platforms according to an embodiment of the present invention.

Referring to FIG. 5 , a plurality of energy transaction servers may exist, and a microgrid platform operated in each of the plurality of energy transaction servers may be connected to other microgrid platforms to enable energy transaction. After energy transaction and management within the single microgrid 501, 502, and 503 is made, if necessary, through energy transaction with another microgrid operating platform that is adjacent and physically capable of energy transaction is established. It is possible to maximize the profits of energy consumption/production entities.

6 is a flowchart illustrating an energy transaction method using a marketplace service according to an embodiment of the present invention.

The renewable energy trading platform can set variables such as real-time trading cycle when starting the marketplace service to suit the environment.

In step 601, the power generation/intermediation operator devices 102 and 103 may predict the amount of power generation and consumption according to the subject using the marketplace service. For example, the energy prosumer may predict a power generation amount that is an expected energy production amount, and may predict an expected energy consumption amount. In addition, the small-scale distributed resource brokerage trader can predict the power generation through the sum of the predicted power generation values of the small-scale distributed resources managed, and predict the consumption through the sum of the managed energy demand.

In step 602, the energy prosumer or small-scale distributed resource brokerage transaction operator may check whether the predicted power generation amount of each managed supply/demand resource is greater than the predicted consumption amount.

If the predicted power generation amount of the managed resource is less than the predicted consumption amount, in step 603, the energy prosumer or small-scale distributed resource brokerage trader consumes the produced energy resources as self-consumption or internal transactions between managed resources, and renewable energy It may wait as long as the trading cycle time set by the trading platform (or set by the energy prosumer or small-scale distributed resource brokerage trader).

If the predicted power generation amount of the managed resource is greater than the predicted consumption amount, in step 604, the power generation operator / intermediary operator (including both supply and demand) uses the marketplace service on the renewable energy trading platform to determine the predicted surplus (consumable time). range) can be traded. The brokerage business may include energy prosumers or small-scale distributed resource brokerage business.

In step 605, it can be checked whether a transaction has been made between the power generation operator / intermediary operator in the new and renewable energy trading platform.

When the transaction is completed, in step 608 , the intermediary may pay the energy price to the exchange, which is the operator of the marketplace service provided on the new and renewable energy trading platform, in real time at the time the transaction is concluded. This can be paid in the form of prepayment at the time the transaction is concluded, which is before the consumption point of the predicted energy demand.

The marketplace service provided on the new and renewable energy trading platform in steps 609-610 may check the consumption deadline suggested by the power generation operator/intermediary operator (including both supply/demand).

In step 611, if the production is performed within the time limit, the exchange may pay the energy price to the supplier.

If the production is not implemented, in step 612, the new and renewable energy trading platform may impose various penalties, such as transaction restrictions and fee increases, to the power generation company. In this case, the price must be returned to the buyer or supplied to the buyer by supplying available energy or unconsumed energy from other power generation companies/intermediaries (including both supply and demand).

After that, if consumption is fulfilled, it waits until the next transaction time and proceeds with the procedure for another transaction. If the transaction is not completed, the exchange trades energy at a wholesale price using the marketplace service. In this case, the wholesale buyer pays the energy price to the exchange. The benefit obtained in the form of such a transaction is that it provides an opportunity to sell the produced energy at a price higher than the wholesale price in the form of matching production and consumption in advance.

In addition, consumers who have predicted consumption will be given the opportunity to consume energy at a price lower than the retail price. In addition, the exchange can be said to be the entity that provides the marketplace service, and by receiving real-time payment, it is possible to avoid the risk that the transaction using the service will not be established. The advantage is that the energy can be resold for additional profit.
