摘　　要：PCS下垂控制技术对于实现PCS的无线互联、即插即用具有重要意义。推导了采用下垂控制的PCS数学模型,分析模型参数对PCS及并联系统运行特性的影响,利用Matalb/Simulink搭建了微电网并联PCS的仿真模型,验证了PCS参数和连线阻抗对并联运行特性的影响。Droop control technology has great significance to implement wireless interconnection and plug and play of PCS. Droop control adopted mathematical model of PCS is derived and effect of the model parameters on the operating characteristics of PCS and parallel systems is analyzed. By using Matlab/Simulink, simulation model for parallel PCS of microgrid is established and effect of PCS parameters and wired impedance on par- allel operating characteristic is verified.
