基于鲁棒下垂控制策略的微网平滑切换
Smooth Switching of Microgrid Operation States Based on Robust Droop Control Strategy
摘要
Abstract
For improving smooth switching of microgrid operation states with droop control,a new robust droop control strategy is designed with a supplementary sliding mode controller to enhance system stability.This paper adopts angle-voltage droop control and sets up state space equation based on droop control structure and real power dynamic equation.In addition,a supplementary nonlinear controller is designed with sliding mode control method to mitigate angle chattering caused by microgrid operation state switching,so that system stability and response rapidity is guaranteed.Simulation results obtained from Matlab platform show validity of the proposed scheme.关键词
