多逆变器下垂协调控制方法综述

Review of the Droop Coordinated Control Method for Multiple Inverters

下垂控制是微电网中多个分布式发电单元(DG)实现功率协调的重要控制方法。对现有的下垂控制方法进行了归类和综述,将其分成有功-频率、无功-电压下垂控制,电压-相角下垂控制和虚拟同步机控制三类,对这三类方法的基本原理和改进方法进行了介绍,为研究人员开展后续研究提供借鉴和参考。

Droop control is an important control method for realizing power coordination among distributed generation units in the micro-grid.This paper summarizes existing droop control methods and categorizes them into three types,namely active – frequency reactive –voltage droop control,voltage – phase angle droop control and virtual synchronous machine control. Furthermore,it introduces basic principles and improvement measures for these methods,thus providing references for research people in their future work.
