摘要
以分布式发电的新能源为背景,分析了基于电压电流双环控制的下垂控制方法的结构和原理,建立了包括负荷投切的微电网运行控制系统仿真模型,对控制策略的具体性能进行了详细分析。结果表明,基于该控制策略的微电网运行稳定,动态响应快,突显了该控制策略易于实现无缝切换的特点。
With the distributed generation of new energy as the background,the structure and principles of the droop control based on voltage and current loop control was analyzed,the micro-grid load switching operation control system simulation model was built,and the specific performance of the control strategy was studied in detail.The results show that the micro-grid based on the proposed control method works stably with fast dynamic response and easy seamless switching characteristics.
