摘要

针对频率-有功功率(F-P)型分布式电源

提出一种适用于交流微网孤立运行时的有功控制策略。该策略充分利用微网中交流电网的天然耦合特性

在不借助分布式电源间或者分布式电源与中央控制器间通信的条件下

实现分布式电源出力自趋优功能。所提出的控制策略具有分层结构

包含频率分层控制和频率跟踪控制两个部分

其主要特点为:适用于以逆变器为接口且工作在电流源模式的分布式电源;完全基于本地信息

在不借助中央控制器和集中通信系统的情况下

能够通过各分布式电源的本地信息实现自趋优控制;该策略按照等微增率准则来分摊负荷

使各分布式电源的成本微增率相等。仿真结果验证了该控制策略的有效性。

Abstract

A self-optimizing power control strategy is proposed for frequency-power(F-P)droop type distributed generators(DGs)in island microgrid. The strategy makes full use of the natural coupling characteristic of alternating current microgrid to control DGs without any communication in the microgrid. The proposed control strategy is twofold: a frequency hierarchical control and a frequency tracking control. Its main characteristics are as follows: 1)it suits the F-P droop type DGs; 2)the control strategy can be realized locally

rendering the microgrid centralized controller(MGCC)and communication network unnecessary; 3)it can make DGs share loads according to the equal increment principle(EIP). Simulation results have verified the effectiveness of the proposed control strategy. This work is supported by National Natural Science Foundation of China (No. 51177146)and National High Technology Research and Development Program of China (863 Program) (No. 2015AA050202).
