摘　　要：分布式电源不断增多以及充电桩等短时大功率负荷的不断增加给传统架构的配网运行带来了挑战。对此,提出了一种适用于低压配电网络的柔性配网架构,并设计了分层分布式的控制系统,针对单路和双路不同进线工况提出了控制策略,包括储能充放电策略、功率转供策略、并离网切换策略。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的可行性。Due to the increasing of distributed power sources and short-term high-power loads such as charging piles, the distribution network of traditional architectures is facing challenges.So a flexible distribution network architecture suitable for low voltage distribution networks is proposed, and a hierarchical distribution control system is designed. The control strategy including charging and discharging strategy of energy storage system, power transfer strategy, onoff- grid switchover strategy are given for single and dual inlet conditions.Finally , the feasibility of the control strategy is verified on the real-time digital simulation(RTDS) platform based on semi-physical.
