Economical Optimization for Multi-Microgrid Based on Stackelberg Game

This paper proposes an economical optimizated strategy for multi-microgrid based on stackelberg game. The microgrid operator is the leader, the microgrids are the followers. The microgrid operator formulates the internal price of microgrids according to its profit in the upper layer; However, every microgrid need to meet the demond response with the goal of maximizing operational benifits in the lower layer. The differential evolution algorithm is used to solve the proposed optimization problem, which improves the energy sharing level between microgrids, reduces the fluctuation of net load power and increases the benefits of multi-microgrid and microgrid operator. Finally, the simulation study is analyzed and the results verify the effectiveness of the proposed strategy.
