摘要
Abstract
In allusion to problems of micro-grid system mode being not fast and smooth in switching,it is suggested to adopt proper control measures to realize grid-connection mode and island mode,as well as smooth switching of these two modes. Therefore,hypotactic micro-grid system with wind power,photovoltaic power and stored energy is established,structure and control method of the main control inverter is analyzed and comprehensive control strategies are summarized. In allusion to existing problems in micro-grid switching,control strategies are improved and dynamic model of micro-grid is established on MATLAB/Simulink platform to conduct simulation analysis on original comprehensive control strategies and improved control strategies. Simulation results indicate that improved control strategies could effectively constrain transient shock of bus voltage of the micro-grid and ensure smoothness of voltage amplitude,phase and current in process of system switching. Results also verify effectiveness and feasibility of designed control strategies.关键词
