摘　　要：采用成本收益模型研究了钠硫电池储能系统在电网削峰填谷作用中的电价机制。从单一容量电价、单一电度电价、两部制电价3种电价机制讨论了固定投资回报期下的储能电价策略。研究结果表明,对于能量型的钠硫电池储能系统,采用单一容量电价机制来制定储能电价不太合适,而采用单一电度电价和两部制电价机制则更为合适。随着钠硫电池储能系统单位能量建设成本从3 000元/kW·h降至1 000元/kW·h,采用单一电度电价和两部制电价机制制定的放电电价可控制在1元/kW·h左右,初步具备了与上海工商业高峰时段电度电价竞争的优势。A cost-benefit analysis model of NaS battery based energy storage system was established to study the electricity pricing mechanism during load shifting of power grid. The energy storage pricing strategies under three electricity pricing mechanisms, namely the capacity pricing mechanism, the energy pricing mechanism and the two-part electricity pricing mechanism, were discussed. Research results show that the energy pricing mechanism and the two-part electricity pricing mechanism are more suitable for the NaS battery based energy storage system than the energy pricing mechanism. Along with the reduction of specific energy construction cost for NaS battery based energy storage system from 3 000 RMB/kWh to 1 000 RMB/kWh, the discharge price of NaS battery based energy storage system, which is set by the energy pricing mechanism and the two-part electricity pricing mechanism, could be controlled to about 1 RMB/kWh, thus it may possess the elementary capability to compete with the Shanghai industrial and commercial electricity price in peak periods.
