摘　　要：以一基于下垂控制的微电网为研究对象,在Matalb/Simulink平台搭建仿真模型。对微电网并负荷和切除分布式电源进行了详细的仿真分析,同时研究了逆变器设置参数对微电网动态特性的影响,得出下垂控制的微电网是一个N+X冗余系统,可以实现DG和负荷的即插即用;调节逆变器设置参数可以调节微电网的动态特性。In this paper,a microgrid based on droop control is the object to research,and the simulation is modeled in Matlab/Simulink.Two cases,that are load connected to microgrid and Distributed Generators(DG) disconnected from microgrid,are analyzed in detail.The influence of control parameters of the inverters on the dynamic performance of microgrid is studied.The conclusion is that the microgrid based on droop control is a N+X redundant system,where it is easy to implement to plug and play for DG and loads,and regulating the control parameters of the inverters can adjust the dynamic performance of microgrid.
