摘　　要：储能技术的复杂性和不同的应用场景,对储能方案成本评估造成巨大的挑战。因此,储能方案成本评估需要基于平准化电力成本,即对储能技术每单位放电电量的成本进行量化。本文针对抽水蓄能、压缩空气储能和磷酸铁锂电池储能3种大规模储能应用系统,结合储能系统全生命周期分析,计算储能系统全生命周期成本,为不同储电方案的成本评估提供了客观统一的标准,可以帮助指导储能系统的发展和革新,确保储能系统在全生命周期具备最佳的经济效益。The complexity of energy storage technology and different application scenarios pose huge challenges to the cost evaluation of energy storage solutions.Therefore,the cost evaluation of energy storage solutions needs to be based on the levelized cost of electricity,that is,the cost of energy storage technology per unit of electricity discharged is quantified.This article focuses on three large-scale energy storage application systems,such as pumped water storage,compressed air energy storage and LiFePO4 battery energy storage.Combining with the full life cycle analysis of the energy storage system,this paper calculates the full life cycle cost of the energy storage system,which may provide objective and unified standard for the cost evaluation of different energy storage solutions.The work of this paper can also help guide the development and innovation of energy storage systems,and ensure that energy storage systems gain the best economic benefits during the entire life cycle.
