Micro-grid group optimization scheduling method based on mixed game

The invention discloses a micro-grid group optimization scheduling method based on a mixed game, and the method comprises the steps: building a transaction model of a micro-grid alliance through the comprehensive consideration of the interests and goals of a plurality of micro-grids, minimizing the operation cost of a power distribution network through upper real-time data and power demand management, determining the electricity price of market transaction, and reducing the loss of insufficient energy supply. The lower layer establishes a cooperation model of a distributed energy microgrid group, reasonably coordinates electric energy of a power shortage microgrid and a residual power microgrid, minimizes line loss generated in an electric energy transmission process, improves energy utilization efficiency, better optimizes energy management, realizes energy transaction and flexible scheduling, and rapidly finds an optimal solution by adopting a particle swarm optimization algorithm.
