Multi-energy complementary micro power grid energy management method containing multiple main bodies

Abstract

The present invention belongs to the electric power system micro power grid technology field, in particular relates to a multi-energy complementary micro power grid energy management method containing multiple main bodies. In order to coordinate the decision main bodies in an energy internet, balance and optimize the benefits of the related parties, the present invention provides the multi-energy complementary micro power grid energy management method containing multiple main bodies. The method is characterized by utilizing a combined cooling heating and power system and a heat storage device, combining the user side electricity demand response and the heat demand response and the renewable energy source power generation, and comprehensively considering the factors, such as the user comfort degree, the optimization cost, etc., to construct a cooperative game composed of the members in a micro power grid, and adopting a Shapley value method to distribute the benefits according to the contribution degrees of the members. The method of the present invention aims to maximize the alliance benefit, guarantees the distribution fairness while realizing the maximum benefit, enables the benefits of the members in an alliance to be improved effectively, and provides an optimization method of lower cost and higher fairness for the economic operation of the multi-energy complementary micro power grid.

Description

technical field [0001] The invention belongs to the technical field of electric power system micro-grid, and in particular relates to an energy management method of a multi-energy complementary micro-grid with multiple subjects. Background technique [0002] With the widespread use of fossil energy, the environmental crisis is getting worse and energy consumption is increasing year by year, and the issue of Energy Internet has attracted widespread attention. Therefore, through the construction of the Energy Internet, it is of great significance to enable the energy system to realize the open interconnection of multiple energy sources and free energy transmission, allow various participants and a large number of users to open access, and realize the optimal allocation of energy resources. However, the scale of subjects participating in decision-making in the Energy Internet will increase sharply compared with traditional power grids. At the same time, there are mutual game ch...
