抽水蓄能和电化学储能电站的经济效益研究

Research on Economic Benefits of Pumped Storage and Electrochemical Energy Storage Power Stations

对储能的经济效益进行评估,可有效激发储能市场活力,促进储能高质量发展。本文从电源侧、用户侧角度出发,通过全寿命周期方法分析储能的各项成本和收益,并以净现值、内部收益率、度电成本等三个经济评价指标,考虑容量价格、年利用小时数、峰谷电价差、初始单位投资成本等四个敏感性因素,较为系统全面地评估储能的经济效益。

Assessing the economic benefits of energy storage can effectively stimulate the vitality of the energy storage market and promote the high-quality development of energy storage.From the perspective of the power supply side and the user side,this paper analyzes the costs and benefits of energy storage through the whole life cycle method,and evaluates the economic benefits of energy storage by taking three economic evaluation indicators,such as net present value,internal rate of return and kilowatt-hour cost,and considering four sensitive factors,such as capacity price,annual utilization hours,peak-valley price difference and initial unit investment cost,systematically and comprehensively evaluates the economic benefits of energy storage.
