摘　　要：分布式光伏发电的随机性和间歇性导致了资源利用率低,而电池储能具备功率快速吞吐、灵活运行的能力,是当前解决光伏并网和消纳的有效手段之一。本文首先针对当前储能成本高、收益模型不清晰等问题进行了研究,随后分别从投资者和社会综合收益角度构建了储能系统经济收益模型,并以最优经济指标对储能进行容量配置,对影响储能经济效益的重要因素进行盈亏平衡和敏感性分析,最后以某分布式光伏系统典型日的数据为基础,对储能系统进行经济分析和容量优化配置,结果表明储能的成本因素对系统经济收益起主要影响作用。The randomness and intermittency of distributed photovoltaic power generation lead to low resource utilization.Battery energy storage can rapid power throughput andflexible operation.It is one of the effective means to solve photovoltaic grid connection and consumption.Aiming at the problems of high energy storage cost and unclear income model,this paper constructs the economic income model of the energy storage system from the perspective of comprehensive income of investors and society.The cost and benefits composition of energy storage are analyzed,and the life cycle benefit model of energy storage is constructed from the perspective of comprehensive income of investors and society,and the energy storage capacity is allocated with the optimal economic index;The profit and loss balance and sensitivity analysis of the important factors affecting the economic benefits of energy storage are carried out;Based on the typical data of a distributed photovoltaic system,the economic analysis and capacity optimization of the energy storage system are carried out.The results show that the cost of energy storage plays a major role in the economic benefits of the system.
