Study on control strategy of smooth switching for micro-grid based on master-slave control
摘要
Abstract
Mode control strategy and control structure of micro-grid in grid connected and islanded operation are dif-ferent , when the micro-grid switches , due to the controller status does not match in two modes , the output of the con-troller will jump and produce larger transient shock .Therefore , according to the master-slave control structure of mi-cro-grid in grid connected mode and island mode and mutual switch , this paper presents a method of PQ control and based on improved droop of the V/F control combination , by adjusting the adaptive droop coefficient and the output of the controller state synchronization control for micro-grid smooth switching control strategy .The micro-grid model is built in Matlab/Simulink to be simulated and analyzed .The simulation results verify the feasibility and effectiveness of the proposed control strategy , which realize the micro-grid smooth switching , reduce the transient shock produced in the process of switching system effectively .关键词
