Line impedance measurement method for micro-grid
摘要
Abstract
The micro-grid is as effective approach to solve the large-scale grid-connected distributed generation , and the power sharing between inverters and micro-grid modeling and stability analysis are hot research field in micro-grid research .To implement power sharing control of micro-grid inverter and establish accurate modeling of micro-grid sys-tem, the feeder line impendence is an important and indispensable parameter .The existing line impedance real-time measurement methods are based on distributed generation and application of large -scale power generation system , which is restricted in micro-grid.This paper summarized and analyzed each of these methods , identified their advanta-ges and weaknesses , and then proposed a line impedance measurement method of micro-grid based on MGCC .The theoretical analysis and simulation results verify the feasibility of the proposed method .关键词
