Description

Interactive information provision system based on demand and supplier negotiation reflecting real-time energy costs and method as the same}

The present invention provides interactive price negotiation information between demand and suppliers by reflecting real-time energy costs of DR resource participants. More specifically, price information for each electricity consumption time and electricity supply unit price of surplus electricity providers are provided by the supplier and the consumer. It relates to a two-way information provision system and method based on demand and supplier negotiations that reflect real-time energy costs that can be provided to everyone and enable real-time power transaction.

In general, power grids are designed so that the demand and supply of electricity are operated in harmony with each other. An indicator of this balance is the frequency, and the stability of this frequency is directly related to the quality of electricity. Currently, it is very difficult to adjust the demand for power in the operation of the power grid because it varies depending on the individual's electricity use. This ensures that the power supply always keeps up with the power demand in real time.

Accordingly, demand management is required to adjust power demand as a way to avoid supplying insufficient power in case of emergency and to minimize environmental problems such as fine dust emission.

The previous national electricity demand management was subdivided into demand management in small-scale distributed power generation at the city level, and in particular, demand management through electricity transactions between citizens in smart cities avoids progressive tax and promotes city electricity stabilization. .

For such electricity transaction, price information of electricity consumption hourly related to the provision of incentives by consumers' voluntary energy saving is required. Excess reduction and surplus due to small-scale solar power generation and energy storage system charging and discharging. There is a problem in that bi-directional negotiation is difficult because there is no system that relays electricity transactions between a supplier and a consumer capable of supplying electricity.

The problem to be solved by the present invention is to induce voluntary electricity saving, peak reduction and avoidance of progressive tax by providing real-time optimal electricity rates by analyzing the consumption patterns of consumers in distributed power generation, and to trade electricity reduction amount according to demand management in the city and surplus electricity The purpose of this is to provide a method for providing information in both directions based on demand and supplier negotiation based on real-time energy costs that can provide information in both directions so that customers can trade.

In order to achieve the problem to be solved, the bidirectional information provision system based on demand and supplier negotiation reflecting real-time energy cost according to the present invention is a demand response resource transaction that adjusts the liquidity of power supply in a city with a distributed power source, A communication unit that acquires power consumption type information indicating the power consumption type of the consumer object, a consumer classification unit that classifies the classification of the consumer object based on the power consumption type information, and a real-time electricity bill for the classified consumer object. It may include a transaction information acquisition unit, and a transaction relay unit that provides bidirectional information to enable price negotiation with a consumer by calculating the amount of surplus power of the consumer object and setting a supply unit price.

The transaction information acquisition unit obtains real-time electricity consumption of the consumer object and contract information concluded with a power supply company, calculates the electricity rate for each time period, predicts the time when the standard target is exceeded based on the information, and uses electricity to avoid progressive tax Dispersion methods can be analyzed.

The transaction relay unit satisfies the consumer's self-consumption with new and renewable energy such as small-scale solar power generation and an Energy Storage System, and the electricity supply price and the purchase price on the demand side so that the remaining surplus power can be traded between consumer objects can be compared and analyzed with the real-time System Marginal Price (SMP) of the electricity trading market to calculate the actual electricity transaction unit price.

In order to achieve the above other problems to be solved, the interactive information provision method based on demand and supplier negotiation reflecting real-time energy cost according to the present invention is a method for supplying demand response resources that adjusts the liquidity of power supply in the city with distributed power sources In the method, obtaining power consumption type information indicating the power consumption type of the consumer object, classifying the classification of the consumer object based on the power consumption form information, real-time electricity price for the classified consumer object Calculating, and calculating the amount of surplus power of the consumer object and setting a supply unit price may include the step of providing interactive information to enable price negotiation with the consumer.

In the step of calculating the real-time electricity rate, the real-time electricity consumption of the consumer object and the contract information concluded with the power supply company are calculated, the electricity rate for each time period is calculated, and based on the information, the time when the standard target is exceeded and avoiding the progressive tax It may include the step of analyzing the electricity usage distribution method for

In the step of providing the interactive information, the electricity supply price and demand so that the consumer's self-consumption is satisfied with renewable energy such as small-scale photovoltaic power generation and an Energy Storage System and the remaining surplus power can be traded between consumer objects. Comparing and analyzing the purchase price of the side with the real-time system marginal price (SMP) of the electricity trading market may include the step of calculating the actual electricity transaction unit price.

According to the method of a two-way information provision system based on demand and supplier negotiation that reflects real-time energy costs according to the present invention, it is to advance the demand management environment in a city-unit distributed power environment such as a smart city, and participate in addition to the previous demand response resource transaction. It is possible to trade incentives for customers' reductions,

In addition, according to the present invention, the electricity supply price and the purchase price on the demand side are traded so that new and renewable energy such as small-scale solar power generation and the electricity stored in the energy storage system can be traded between consumers other than their own consumption. It can be set against the real-time system marginal price (SMP) of the market.
