Abstract: As the microgrid technology develops rapidly, regional multi-microgrid systems integrated into the distribution network have become more and more common.The paper proposes a scheduling method based on the cooperative game strategy. It first establishes a cooperative alliance for the multi-microgrid systems to make them exchange power. Then, sub-microgrids and distribution networks exchange power to improve the economy of multi-microgrid system. In the paper, the multi-microgrid system is introduced and the typical power source is modeled. Through introducing the basic concept of cooperative game theory, the grid-connection multi-microgrid scheduling model based on cooperative game theory is established, and the cooperative income is distributed by Shapley value method. The effectiveness of this strategy is verified by examples.
