Virtual Synchro Multi-machine System Participation Analysis and Parameter Optimization
摘要
Abstract
Virtual synchronous generator(VSG)as an emerging converter control method,for the VSG multi-machine parallel system dynamic characteristic analysis is difficult and parameter optimization is complicated,a VSG multi-machine parallel system stability analysis and parameter optimization method is proposed.The method is based on the VSG state space model,and adopts the combination of characteris-tic root trajectory,participation factor and time-domain simulation to analyze the variation of characteris-tic root and its influencing factors,to give the stability margin of the VSG system,and then take different values for the parameters that need to be improved,and select the best value of frequency dynamic response as the optimized parameter value,and finally verify the method by semi-physical simulation through dSPACE to further verify the superiority of the method.关键词
