摘　　要：分析了基于储能系统的户用光伏并网发电系统的结构特点及工作特性,提出一种高效的能量管理策略,研究储能系统(蓄电池)失效进程对用户经济效益的影响,并通过具体算例对比分析无储能系统的光伏并网发电系统和基于储能系统的光伏并网发电系统的运行经济性,最后,考虑光伏并网电价在未来的下降趋势,论证了基于储能系统的户用光伏并网发电系统的长远经济性优势。Characteristics and structure of user＇ s grid-connected PV system based on energy storage system was analyzed, and an efficient energy management strategy was proposed, and the impact of ageing process of the energy storage system （battery） on economic benefits of users was studied. Economic performance of the energy management of both the user＇ s grid-connected PV system based on energy storage system and the system without energy storage system was analyzed through specific examples. Finally, considering the downward trend of photovohaic electricity price, the long-term economic advantage of the system based on energy storage system was demonstrated by analyzing the results of the examples.
