Microgrid electric power market dual-layer bidding method based on multi-agent system and game method

Abstract

A microgrid electric power market dual-layer bidding method based on a multi-agent system and the game method comprises: constructing a dual-layer bidding system based on multi-agent system, dividing an actual electricity market into two electricity submarkets, and in the upper layer of the electricity market, allowing a microgrid to participate in market bidding with traditional generation companies in an alliance mode; in the lower layer of the electricity market, taking the market shares obtained by the microgrid alliance in the competition of the upper layer of the electricity market as a market requirement amount, performing market competition between the microgrids again, and finally taking the obtained market shares as the final electric quantity obtained by the microgrids in the whole electricity market competition; constructing an electricity market dual-layer bidding model based on the game method; performing solution of the upper layer of the electricity market; performing solution of the lower layer of the electricity market; and verifying the utility validity of the dual-layer bidding system based on the multi-agent system through a simulation experiment. The microgrid electric power market dual-layer bidding method based on the multi-agent system and the game method improve the proportion of renewable and clean energy resource provided by the microgrid in the energy market.

Description

technical field [0001] The invention belongs to the field of market transactions of micro-grids, and in particular relates to a two-layer bidding method for micro-grids market based on multi-agents and a game method. Background technique [0002] As a part of the smart grid, the microgrid is a power system that effectively integrates and utilizes distributed energy and improves the utilization rate of green and clean energy. With the maturity of micro-grid related technologies, the problem of dealing with the remaining capacity of micro-grid has gradually become the focus of scientific research. In recent years, with the reform of electricity marketization worldwide, my country has also begun to gradually implement the reform of electricity marketization with the pilot project of "separating the factory from the grid and bidding for the grid", so as to realize the goal of optimizing the allocation of resources and maximizing the social benefits of resources. Purpose. Theref...
