摘　　要：为充分利用分布式电池储能单元(Distributed Battery Energy Storage Units,DBESU)的自恢复效应,延长DBESU放电时间和提高DBESU容量利用率,提出一种计及自恢复效应的电池储能单元容量利用率提升策略。在DBESU工作在非连续模式放电场景下,该策略可控制荷电状态(State-of-Charge,SOC)低的DBESU停机,利用自恢复效应进行SOC恢复;可控制SOC高的DBESU继续工作以便支持负荷及调压调频。该策略在提高孤岛微电网DBESU容量利用率的同时,延长了DBESU的放电时间。最后,不同方案的仿真对比结果验证了本研究方案的有效性和先进性。In order to make full use of the self-recovery effect of the distributed energy storage units,prolong the discharge time and improve capacity utilization of the DBESU,a capacity utilization improvement strategy of battery energy storage unit considering self-recovery effect is proposed.This scheme can make the DBESU with low SOC shutdown,make SOC recover self-recovery effect,and keep the DBESU working with high SOC so as to support the load,voltage and frequency regulation.This strategy improves the capacity utilization of the DBESU in island micro-grid and prolongs its discharge time.Finally,the simulation results of different schemes verify the effectiveness and advancement of the scheme.
