摘要: 基于目前中国分布式光伏政策及储能发展现状,对分布式光伏系统和分布式光伏-储能系统2类系统在中国发展的经济性进行了评估,并基于评估结果,为促进其发展提出了建议。给定分布式光伏-储能系统结构和运行方式,建立了经济模型;以天津市光照条件为例给出光伏系统年出力曲线,区分分布式光伏系统和分布式光伏-储能系统这2类系统,在单一电价模式下以及分布式光伏系统分时电价模式下,对2类负荷特性不同的用户的经济性进行评估和比较,发现光伏系统和储能成本、电价模式及负荷特性均是影响用户安装光伏-储能系统的经济性的重要因素,不同用户适合安装的系统类型不同;建议从降低系统成本、实施分时电价和对用户分类等3个角度,推广和发展分布式光伏-储能系统。

Abstract: According to the current policy of distributed photovoltaic(PV) and energy storage development in China, the economic evaluations of the distributed PV system and PV-energy storage system (PV-ESS) are made with the suggestions for PV system development being put forward. Firstly, given the PV-ESS structure and its system operation mode, the economic model of PV-ESS is established. Then, based on the sunshine condition in Tianjin, the PV output power curve is obtained and the economies of distributed PV and PV-ESS are evaluated and compared under the tariff modes of flat rate tariff and time-of-day tariff for different customers with different load curves. The results show that the cost of PV system and energy storage system, the tariff mode and the load characteristics are the major factors that influence the economy of PV-ESS development for different customers. At last, the suggestions are given for PV and PV-ESS promotion and development from the aspects of cost reduction, time-of-day tariff implementation and user classification.

Key words: photovoltaic (PV) system, distributed photovoltaic-energy storage system (PV-ESS), economic model, load characteristic, tariff mode, economic evaluation process, strategic development suggestions
