Microgrid electrical energy random matching transaction method

Abstract

The present invention discloses a microgrid electrical energy random matching transaction method. The method comprises the following steps: (1) a large power grid determining power purchase and sale prices in the next time period and the allowed maximum purchase and sales quantities of electricity for each microgrid, and delivering to each microgrid; (2) as market participants, a distributed power source, a power consumer and an electrical energy random prosumer of the microgrid separately reporting a price and a transaction volume to the microgrid in advance; (3) as a market operator, the microgrid formulating and calculating a market parameter, delivering to the distributed power source, the power consumer and the electrical energy random prosumer, and declaring the opening of a random matching transaction market; (4) the market participants separately determining the purchase and sale electrical quantity, autonomously selecting a suitable bidding strategy, and reporting to the market operator; (5) the market operator delivering a random matching transaction result to each market participant, and randomly matching closing of transaction markets; (6) the market participants receiving and obeying the random matching transaction result; (7) the market operator reporting a purchase power quantity and sale quantity required by the power grid, and starting real-time electrical energy transaction; and (8) ending the real-time transaction, performing error compensation settlement according to a difference with a random matching transaction volume, and performing a price subsidy to an actual power generation amount of the distributed power source.

Description

technical field [0001] The invention relates to a micro-grid of a power system, and more specifically, to a method for random matching and trading of electric energy of a micro-grid. Background technique [0002] Under the demand of the country to vigorously promote the development of clean energy, and the gradual maturity of Distributed Energy Resource (DER, Distributed Energy Resource) technology, the main body of the power generation side will also show a trend of diversification, and there will be more and more DER and Prosumer (electric energy production and sales) Or, that is, independent users with DER) to participate in the electricity market competition. The traditional micro-grid power trading of "spontaneous self-use and surplus power connected to the grid" is no longer suitable for the needs of power market reform, and a new competitive power trading mechanism is urgently needed to realize the rational allocation of power resources.
