Conventionally, in order to use distributed energy resources, power retailers have been used to use demand resources for energy requested by consumers based on a single form of distributed resources. However, this method has limited efficient use of energy consumption according to fixed energy prices.

In addition, since renewable energy has variable, unpredictable and intermittent characteristics, the balance between demand and supply is very important, and demand-side management (DSM) is used to manage consumer demand.

The power consumer may transmit an energy request message including an energy requirement of the power consumer as necessary energy to receive energy as required according to the amount of energy consumed. The energy mediation device may receive an energy request message including different energy requirements from at least one power consumer.

In step 402, upon receiving the energy request message, the energy mediation device may determine a dynamic price of generated energy generated through distributed resources possessed by the power provider for each time slot. The energy mediation device may analyze a power consumption pattern of a power consumer before determining a dynamic price of generated energy. In other words, upon receiving the energy request message, the energy mediation device may authenticate the power consumer requesting energy supply using personal identification information included in the energy request message. Here, authentication means that it is possible to check whether a power consumer requesting an energy request message is a power consumer already registered in the power grid.

When authentication of the power consumer is completed, the energy mediation device may update the energy request message transmitted by the power consumer and profile the power use history of the power consumer based on the updated energy request message. The energy mediation device may analyze the power consumption pattern of the power consumer based on the profiled power consumer's power use history.

The energy mediation device may distinguish a peak time period (Peak) and a non-peak time period (Non-Peak) of energy according to the energy requirements of the energy request messages recorded and accumulated in the power use history. The energy mediation device may analyze a power consumption pattern of the power consumer by analyzing daily, monthly, and annual power consumption of the power consumer according to the divided time zone.

When the power consumption pattern of the power consumer is analyzed, the energy brokerage device may determine a dynamic price of generated energy generated through distributed resources possessed by the power supplier for each time slot. In this case, the power supplier may request the energy mediation device to register the charging amount of the generated energy generated at regular time intervals. The energy mediation device may register a charge amount of generated energy for each power provider at the request of the power provider. The energy intermediary device may determine the same or different dynamic prices of generated energy for each time slot of the unit of time.

In step 403, the energy mediation device may determine an energy distribution amount that can be supplied to the power consumer in consideration of the dynamic price of generated energy. To this end, the energy mediation device may determine a supplyable energy distribution amount in consideration of a dynamic price determined during a peak time period of power consumption of a power consumer according to a power consumption pattern.

In order to optimize the interests of the power supplier and the power consumer, the energy brokerage device determines the amount of energy distribution traded by the power consumer to the power supplier in a time slot by considering the sum of utilities for a plurality of power consumers capable of trading energy with the power supplier. can Accordingly, the energy mediation device may determine an energy distribution amount that can be supplied to the power consumers so that the energy demand of the power consumers does not exceed the generation amount of the generated energy for each time slot of the power consumers.

In order to increase energy use efficiency, the power consumer of the present invention may request energy supply and utilize surplus energy produced from demand resources possessed by the power consumer. Accordingly, the energy mediation device may determine whether there is surplus energy produced from demand resources possessed by the power consumer in consideration of the power consumption pattern of the power consumer. If there is surplus energy, the energy mediation device may determine an energy distribution amount obtained by subtracting a charging amount of surplus energy according to an energy demand.

In step 501, the energy mediation device may receive an energy request message based on the power consumption of the power consumer and analyze a power consumption pattern according to the power consumption history of the power consumer. In detail, when a power consumer requests an amount of energy required by the power mediator device, the energy mediation device may evaluate the energy request message of the power consumer. In addition, the energy mediation device may profile the evaluated energy request message and analyze the power consumption history of the power consumer for the profiled energy request message. The energy mediation device may analyze a power consumption pattern according to the power consumption history of the power consumer.

In step 502, the energy brokerage device may set a dynamic price for energy transaction with the power consumer in consideration of the amount of power generation generated from distributed resources possessed by the power provider. Here, the dynamic price may be determined as a generation price at a point in time when the amount of generated energy produced through distributed resources possessed by the power supplier satisfies the energy demand of the power consumer, that is, the market price.

In step 503, the energy mediation device may determine an energy distribution amount that can be supplied to the power consumer for each time slot in consideration of a power consumption pattern and a dynamic price. In this case, when surplus energy generated from demand resources possessed by the power consumer exceeds a minimum charging amount of the energy storage device of the power consumer, the excess surplus energy may be resold through the energy mediation device. Power consumers can benefit from reselling surplus energy. The energy intermediary device may determine a distribution amount of energy that can be supplied to the power consumer in consideration of the amount of generated energy generated by the power provider and the charged amount of surplus energy generated from demand resources possessed by the power consumer.

In step 504, when the transaction between the power consumer and the power supplier is completed, the energy brokerage device may determine an incentive corresponding to the power consumer's gain and/or the power provider's gain generated during the energy transaction.

The energy brokerage device considers a transaction between a power consumer and a power supplier or a transaction between a power consumer and a power consumer in the concept of a prosumer, and determines the power consumer's profit generated in the energy transaction process and/or the incentive corresponding to the power supplier's profit. and can provide.
