As an effective supplement to the power grid, microgrid systems can make full use of renewable energy and solve the problem of grid connection and absorption of renewable energy. However, microgrid faces the challenges of benefit fluctuation caused by fixed pricing mode with unstable renewable energy supply and changing user’s demand. A well-designed pricing mode is necessary while yet to be fully discussed. To solve this problem, this paper introduces flexible operational strategies and pricing mechanism due to the regional differences in resource endowment, microgrid technology mix, user demand and electricity price of external grid. The evolutionary game method is used to explore the operational strategy and pricing mechanism applicable to microgrids with different characteristics and users with different demands, so as to provide valuable reference for pricing standardization of microgrids in China. Based on the theoretical model, we deduce the equilibrium strategy of microgrid facing stable users and flexible users, and discusses the operational strategy and pricing mechanism of microgrid facing different user demands by using numerical simulation method. The results indicate that: (1) Considering the technical characteristics and economic performance, most of the microgrids tend to be connected to the grid and use real-time pricing mode. (2) The initial price between the microgrid and the user, the proportion of independent power generation when the microgrid is connected to the grid, and the tariff of the external grid are the key factors affecting the equilibrium point of the game between the microgrid and the users.
