基于改进下垂控制的微电网有功与频率控制策略
Active and frequency control strategy of micro-grid based on improved droop control
摘要
Abstract
On the basis of analyzing the process of the traditional droop control system to adjust the active power and frequency,two improvement strategies of micro-grid operation in grid connected and isolated mode are proposed in this paper.Using the improved control strategy,micro-grid can operate at the rated frequency after reaching steady state in isolated mode.Inverter based source can supply active power according to the preset of the active power value automatically in grid connected mode,and for energy storage device,it will convert to absorb active power from the grid,and for adjustable micro source,it can supply a rated active power.Finally,the Matlab/simulink simulation results validate the effectiveness of the proposed strategy.关键词
