摘要

孤岛交流微电网内分布式储能系统（DESS）采用传统的P-f下垂控制时存在健康状态（SOH）不平衡问题。针对此问题,提出一种基于多代理的DESS组间SOH平衡方案。该方案中各个DESS代理之间进行放电深度（DOD）信息交互,根据DESS的SOH状态对DESS逆变器输出有功功率进行调节,实现DESS的SOH平衡,延长DESS的使用寿命,降低微电网的维护成本。最后,利用PSCAD仿真软件和搭建的实验平台进行仿真和实验验证,仿真和实验结果验证了所提方案的有效性。

Abstract

Aiming at the problem of state of health （SOH） imbalance of distributed energy storage system（DESS） in islanded AC microgrid when adopting conventional P-f droop control, a SOH balance scheme based on multi-agent is proposed. Through the information interaction of depth of discharge （DOD） among DESS agents, the SOH balance of DESS is realized. The service life of DESS is prolonged and the maintenance cost of microgrid is reduced by adjusting the active power output of DESS according to the SOH state of DESS. Finally, the PSCAD simulation software and the experimental platform are used for simulation and experimental verification, which indicates that the proposed scheme is effective.
