In order to reduce the unnecessary energy interaction between the microgrid and the distribution network, while promoting the local accommodation of wind power, this paper presents an energy transaction mode of regional microgrid cluster and distribution network. Firstly, the mode integrates the load demand and wind power output in the area based on regional multi-microgrid operator. And then, the transaction mode uses the load transfer rate to describe the user response of time of use (TOU) price. Meanwhile, the mode also establishes a model for the TOU price of regional microgrid cluster system considering the uncertainty of wind power. Finally, an NSGA-II algorithm is used to solve the multi-objective optimization problem in the model. Based on the experimental results, the transaction mode achieves cost reduction of microgrid cluster, while reducing unnecessary interaction between the regional microgrid cluster system and the distribution network.
