摘要随着电网中分布式电源的日益增多,储能技术在提高系统的稳定性和改善电能质量方面显得越来越重要。考虑到当前储能元件的特性,复合储能系统比单一储能系统具有更多优点,但当前复合储能技术多基于主从控制,需要高带宽通信,系统可靠性被削弱,不适合于分布式特点的直流微网。从提高直流微网中储能装置的扩展性及冗余度角度出发,提出了一种新型复合储能装置的并联控制策略。该策略中,电池采用电压-电流(U-I)下垂控制,超级电容采用电压变化率-电流(U′-I)下垂控制。该系统在仅依靠储能装置本地信息时,实现不同类型储能装置响应对应频段的分量和同类型储能装置之间的功率自动分配。最后,仿真和实验结果验证了该策略的正确性和有效性。

Abstract：With more and more implementation of renewable energy sources within power systems,energy storage technologies will be ever more important for improving system stability and power quality.Compared with the single energy storage system,hybrid energy storage system has more advantages in view of characteristics about present storage elements.However,present hybrid energy storage technologies are mainly based on master-slave control strategy which needs high bandwidth communication.Consequently,its reliability is reduced and that kind of control is not suitable to distributed DC microgrid.Considering the expansion and redundancy of same type storage units,this paper presents a novel parallel control strategy for hybrid energy storage units.In this control system,batteries use U-I droop control and supercapacitors use U′-I droop control.By using local information about storage units alone,the system can compensate different frequency components with different type storage units and share power among same type.Finally,the simulation and experimental results are presented to verify its correctness and effectiveness.

Key words： Hybrid energy storage system droop control parallel control DC microgrid
