摘　　要：为应对日益增长的微网群系统稳定性、经济性运行控制需求,提出了一种考虑并网和孤岛运行模式的微网群系统分布式控制方法。方法基于一致性算法实现微电网分布式分层控制,并考虑了微网群内各微网的协调控制。Simulink仿真结果表明,在负荷投切等情况发生时,工作在并网或孤岛模式的微电网群系统频率、电压波动在合理范围内,分布式电源始终按照等微增率原则分配出力。所提微电网群系统分布式控制方法能够维持微电网群的频率稳定和电压稳定,并通过分布式电源出力分配实现经济性目标。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.
