In response to the increasing demand for stable and economic operation control of microgrid cluster systems,a distributed control method for microgrid cluster systems considering grid connection and island operation modes was proposed.The method was based on consistency algorithm to achieve distributed hierarchical control of microgrids,and the coordinated control of various microgrids was considered within the microgrid group.The simulation results of Simulink show that when load switching occurs,the frequency and voltage fluctuations of the microgrid group system operating in grid connected or island mode were within a reasonable range,and the distributed power generation always distributed power according to the principle of equal incremental rate.The proposed distributed control method for the microgrid system can maintain frequency stability and voltage stability of the microgrid group,and achieve economic goals through distributed power output distribution.
