Abstract	The operation mode of microgrids influences the dispatching management of distribution system in the power market. The study uses game theory to study dispatching strategies between multi-microgrid in the distribution system. For this purpose, a two-level game model of multi-microgrid dispatching in the electricity market is proposed. Firstly, the upper level of the model researches the answer of a basic question for a multi-microgrid distribution system that what the boundary line between non-cooperation mode and coalition mode is. Secondly, by the lower level of the model, multi-microgrid decides the operation mode ultimately when it is uncertain in the upper level of model. The upper level is a non-cooperative price game between multi-microgrid and distribution system while the lower level is a cooperative trading loss cost game. In order to optimise multi-microgrid dispatching, an algorithm is proposed to allow microgrids merge or split self-adaptively based on NSGA-II. Simulation result shows that the proposed algorithm can find the Nash equilibrium of the upper level of the model and the optimal operation mode for multi-microgrid in the two-level game, which yields a reduction of 52.7% in coalition mode compared to non-cooperation mode.
