A Study of Demand-Side Multi-Microgrid Trading Based on Non-Cooperative Games

In this paper, based on the non-cooperative game theory, the power trading problem in a multi-microgrid system containing controllable distributed power sources is investigated. Firstly, a non-cooperative game model is established, and the power trading behaviour between distribution grids and microgrids is included in the model and the corresponding rules are set. Secondly, a non-cooperative game model in the trading of multiple microgrid systems with the participation of distribution grids is constructed, and the existence of Nash equilibrium point of this game model is proved theoretically. Finally, an example analysis and simulation solution are carried out for multiple microgrids to verify the effectiveness of the model and its practical application.
