摘　　要：大容量电池储能系统的分散式一次调频控制可能会产生功率环流和振荡。对此,分析了分散式一次调频控制产生功率环流的机理,提出了一种集中式一次调频控制系统架构和控制策略,同时给出了集群控制器的功率分配方法和控制流程,最后在基于半实物的实时数字仿真(RTDS)平台上试验验证了控制策略和功率分配方法的正确性。The decentralized primary frequency regulation of large-capacity battery energy storage system may generate power circumfluence and oscillation.The mechanism of power circumfluence generation by decentralized primary frequency regulation is analyzed,a centralized primary frequency regulation architecture and strategy are proposed.Also a power allocation method and control flow of cluster controller are given.The experiment with the platform based on semi-physical real-time digital simulation(RTDS)verifies the validity of the control strategy and power allocation method.
