Comparison of dynamic characteristics between single-loop and dual-loop inverters with droop control in micro-grid based on small-signal model
摘要
Abstract
Droop control is one of the common control strategies of micro-grid inverter.Firstly,small-signal models of micro-grid inverters are established respectively based on single-loop droop control and dual-loop droop control.Secondly,the impact of droop parameters and load parameters on distribution of eigenvalues is studied,which provides theoretical basis for droop parameter design.Finally,step responses with the load increased by 20％ are obtained from simulation in MATLAB/Simulink.The conclusion is that dual-loop droop control has better stability and dynamic response performance than single-loop droop control.关键词
