本文对农村家庭采用电池-超级电容器混合储能系统的单机光伏系统(BS-HESS)与传统的单机光伏系统进行了比较。本文提出了无源BS-HESS和半有源BS-HESS的独立光伏系统。针对半有源BS-HESS独立光伏系统，提出了两种控制策略：基于规则的控制器(RBC)和基于过滤的控制器(FBC)，以降低电池应力，延长电池寿命。仿真结果表明，与纯电池系统相比，半有源BS-HESS系统的电池峰值电流降低了8.607%，电池的平均SOC提高了0.34%，从而延长了电池的使用寿命。
This paper presents the comparison between the standalone photovoltaic (PV) system with battery-supercapacitor hybrid energy storage system (BS-HESS) and the conventional standalone PV system with battery-only storage system for a rural household. Standalone PV system with passive BS-HESS and semi-active BS-HESS are presented in this study. Two control strategies, Rule Based Controller (RBC) and Filtration Based Controller (FBC), are developed for the standalone PV system with semi-active BS-HESS with the aim to reduce the battery stress and to extend the battery lifespan. The simulation results show that the system with semi-active BS-HESS prolongs the battery lifespan by significantly reducing the battery peak current up to 8.607% and improving the average SOC of the battery up to 0.34% as compared to the system with battery-only system.
