基于μPMU的孤岛微电网多源协调控制方法
Multi-source coordinated control method based on μPMU for islanded microgrid
摘要
Abstract
The peer-to-peer control method of islanded micro-grid has the problem of large frequency control devia-tion,low power distribution accuracy,difficult power plug-and-play,and complex control of multi-area micro-grid interconnection.Therefore,this paper proposes a multi-source coordinated control method based on μPMU for is-landed microgrid.The method is composed of I-U droop and the current loop cascade.The timing signal of μPMU is used to generate the same virtual internal potential with the same amplitude and phase in each distributed power supply,fix the microgrid frequency at 50 Hz,and realize the power plug-and-play and flexible interconnection of the multi-area microgrid.The bus voltage provided by μPMU is used to participate in I-U droop control,restrain the circulation between power sources,improve the power distribution accuracy,and reduce the voltage control de-viation.Besides,based on the small-signal model,the influence of load and line parameters on system stability is analyzed,and the reasonable control parameters are determined by solving eigenvalue trajectories.The feasibility and effectiveness of the proposed method are verified by simulation and experiment.关键词
