基于T-S模糊模型的E-FMSS大信号稳定性分析
T-S Fuzzy Model Based Large-Signal Stability Analysis of E-FMSS
摘要
Abstract
Flexible interconnection devices are conducive to improve the ability of the distribution network to carry large-scale distributed sources and loads.The interaction and coupling among a high proportion of power elec-tronic devices affect the operational stability of the distribution network.To quantify the impacts of system parame-ters,control modes and control parameters on the stability in the interconnected system of E-FMSS(Energy-storage Flexible Multi-State Switch)between different distribution areas,this study investigates the large-signal stability of E-FMSS based on the T-S fuzzy model.According to the topological structure and control strategy of E-FMSS,the T-S fuzzy model is deduced.An estimation method of the region of attraction based on this model is proposed,and the influences of main circuit parameters,parameters representing the operating point information and control parame-ters on the large-signal stability of E-FMSS are analyzed using the region of attraction.By comparing and analyzing the theoretical analysis results with the time-domain simulation results,the correctness of the method for judging the large-signal stability of E-FMSS by estimating the region of attraction based on the proposed T-S fuzzy model is veri-fied.关键词
