Smooth Switching Strategy for Flexible Multi-state Switch During Distribution Network Faults
摘要
Abstract
With the rapid development of distributed energy and microgrid,the control of distribution network encounters numerous challenges.In this paper,we propose a flexible multi-state switch port control switching strategy for micro-grid out-age caused by power failures in distribution networks.Firstly,a mathematical model of normal grid-connection and fault off-grid process of distribution network is constructed.Addition-ally,an analysis is conducted on the control strategy and work-ing mechanism of flexible multi-state switch(FMSS)under two different operating conditions,distribution networks in normal state and faulty state.Secondly,the smooth switching of FMSS control strategies under different working conditions is studied,and the state tracking control compensation method is intro-duced based on the original theory to address the limitations of the existing strategies.Then,an adaptive control strategy with phase pre-synchronization control is introduced,enabling ef-fective mitigation of the impact caused by distribution network failure and power outage.Finally,the effectiveness of the pro-posed control strategy is verified through simulation experi-ments in Matlab/Simulink.关键词
