| 摘 要： | 微电网的协调控制方法是微电网最为关键的技术之一,主从控制方法是微电网协调控制中的常用方法。针对传统的主从控制存在的问题,提出了一种带辅助微源的新型主从控制策略。在传统主从控制基础上,增设一个采用下垂控制的辅助控制单元,此辅助单元可与主控单元一起共同支撑微电网的电压与频率稳定,且当主控单元出现故障时可替补充当新的主控单元,克服了传统主从控制采用单一主控单元发生故障时微电网崩溃的危险,从而增强了主从控制方式的稳定性。MATLAB/Simulink软件仿真验证了所提控制策略的有效性和可行性。

| Abstract: | The coordination control method of microgrid was one of the most important technologies in microgrid, and the master slave control method was a common method in the coordinated control of microgrid. Aiming at the problems existing in the traditional master slave control, a new type of master slave control strategy with auxiliary micro source was presented. On the basis of traditional masterslave control, it added a droop control of auxiliary control unit which could be with the main control unit together to support micro network voltage and frequency stability, and could be the new main control unit when the main control unit fails. The method overcame the danger that the traditional master slave control system adopted a single main control unit , and the stability of the master slave control mode was enhanced. The effectiveness and feasibility of the proposed control strategy were verified by MATLAB/Simulink software simulation. |
