Abstract

The invention discloses a multi-virtual power plant joint optimization scheduling method based on a master-slave cooperative game, and belongs to the field of power system power supply scheduling. Themethod comprises the following steps of: establishing different types of virtual power plant optimization scheduling models; establishing a master-slave game model of a power distribution network operator and the plurality of virtual power plants based on the established different types of virtual power plant optimization scheduling models, and iteratively solving the master-slave game model in combination with a particle swarm algorithm to obtain a solving result; and according to the solving result, adopting a Shapley value method to carry out cooperative profit redistribution, and outputting a final solving result. Specifically, the established different types of virtual power plant optimization scheduling models comprise a more-electricity type virtual power plant scheduling model, aless-electricity type virtual power plant scheduling model and a self-balancing type virtual power plant scheduling model. According to the method, an optimal transaction strategy that the power distribution network operator and the virtual power plants participate in the power market can be solved, electric energy sharing among the multiple virtual power plants is promoted, the comprehensive utilization efficiency of distributed energy is remarkably improved, and nearby consumption and reasonable scheduling of various distributed power generation resources can be achieved.

Description

technical field [0001] The invention relates to a multi-virtual power plant joint optimization scheduling method based on a master-slave cooperative game, and belongs to the technical field of power system scheduling. Background technique [0002] In recent years, distributed power generation based on renewable energy has developed rapidly. However, the characteristics of small capacity, large quantity, scattered access and intermittent output of distributed power have limited its large-scale development. Aggregating renewable energy in the form of virtual power plants (virtual power plants, virtual power plants), controlling each aggregation unit through an energy management system, can realize the coordinated and optimized operation of the aggregation units, thereby improving the stability of virtual power plants and their competitiveness when participating in the electricity market. and benefit from economies of scale. The power market that virtual power plants can parti...
