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

The new and renewable energy trading platform can set parameters such as real-time trading cycle to suit the environment when the market place service starts.

In step 601, the generation/brokerage service provider devices 102 and 103 may predict the amount of power generation and consumption according to the entity using the market place service. For example, an energy prosumer can predict the amount of power generation, which is expected energy production, and predict the expected amount of energy consumption. In addition, the small-scale distributed resource brokerage business operator can predict the amount of power generation through the sum of predicted values of the generation amount of the small-scale distributed resources under management, and predict the consumption through the sum of energy demand under management.

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

If the predicted generation amount of the resource being managed is smaller than the predicted consumption amount, in step 603, the energy prosumer or small-scale distributed resource brokerage business operator consumes the produced energy resource through self-consumption or internal transaction between managed resources, and uses renewable energy You can 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 operator).

If the predicted generation amount of the resource being managed is greater than the predicted consumption amount, in step 604, the power generation company / brokerage company (including both supply / demand) predicts the surplus amount (consumable time) using the marketplace service on the renewable energy trading platform. scope) can be traded. Brokerage business operators may include energy prosumers or small-scale distributed resource brokerage business operators.

In step 605, it is possible to check whether or not a transaction has been concluded between the power generation company/intermediary company in the renewable energy trading platform.

When the transaction is concluded, in step 608, the brokerage company may pay the energy price in real time to the exchange, which is the operator of the market place service provided on the renewable energy trading platform, at the time of the transaction. This can be paid in advance at the time of transaction completion, prior to the consumption of energy forecast demand.

In steps 609 to 610, the market place service provided on the renewable energy trading platform can check the expiration date suggested by the power generation company/brokerage company (including both supply/demand).

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

If production is not fulfilled, in step 612, the renewable energy trading platform can impose various penalties such as transaction restrictions and fee increases to power generation operators. At this time, it is necessary to return the price to the purchaser, or supply available energy or unconsumed energy from other generators/brokers (including both supply and demand) to the purchaser.

After that, if the consumption is fulfilled, it waits until the next transaction time before proceeding with another transaction. If the transaction does not go through, the exchange trades energy at wholesale prices using the marketplace service. In this case, the wholesale buyer pays the energy price to the exchange. The benefit obtained in the form of this transaction is that production and consumption are predicted and matched, providing producers with an opportunity to sell the produced energy at a higher price than the wholesale price.

In addition, consumers who have anticipated consumption are given the opportunity to consume energy at a lower price than the retail price. In addition, the exchange can be said to be the entity that provides the market place service, and it is possible to avoid the risk that a transaction using the service will not be established by receiving real-time payment, and if the predicted consumption is not fulfilled, it is applicable to wholesale buyers The advantage is that additional gains can be made by reselling the energy.
