摘    要:目前分布式能源的开发和应用日趋广泛。对直流侧含有超级电容器和锂电池的混合储能系统(HESS)的模糊PI控制进行了研究,采用有源并联结构,锂电池和超级电容器分别由两个两相交错并联Buck-Boost型双向DC/DC变换器与直流侧连接。基于MATLAB Simulink仿真工具建立了系统模型,分析了混合储能系统的充放电控制过程。通过模糊PI控制仿真结果与普通PI控制仿真结果相比较验证了所提出方法的有效性。

关 键 词:分布式发电(DG)  混合储能系统(HESS)  双向DC  DC变换器  模糊PI控制  超级电容器

Abstract:Distributed energy has been widely developed and applied. This paper studies a fuzzy PI control of the hybrid energy storage system( HESS) containing a super capacitor and lithium battery on its DC side. The system adopts an active parallel structure,and the lithium battery and super capacitor are connected to the DC side via two phase-crossed parallel Buck-Boost bidirectional DC / DC converters,respectively. A system model is established through MATLAB Simulink simulation tool,and the charging and discharging control processes of the hybrid energy storage system are analyzed. The comparison between the simulation results of the fussy PI control and ordinary PI control verifies the effectiveness of the proposed method.
Keywords:distributed generation(DG)  hybrid energy storage system(HESS)  bidirectional DC /DC converter  fuzzy PI control  super capaci-tor
