基于成本分析的用户侧储能方案经济性评估模型研究

Study on Economic Evaluation Model of User-Side Energy Storage Scheme Based on Cost Analysis

针对目前储能电池在电力系统中的大量投用,尤其在用户侧层面的日益增加,如何在降低投资成本前提下缩短收益回报时间。对用户侧储能方案进行经济性评估分析,分别对投资成本、运营成本、需量电费管理收益、峰谷套利收益、调频服务收益和需求响应收益进行分析,并结合江苏省现行峰谷负荷变化曲线,通过储能每日充放电次数和是否参与企业负荷削峰服务提出2种储能收益方案,同时得到2种储能方案经济性评估总模型。以某企业储能设备为例进行经济性评估,得出在2种储能方案下获得的收益对比结果。研究成果对当前储能设备商业投资具有一定的指导意义。

In view of the large amount of energy storage battery in the power system,especially the increase in the user-side,it is very important to reduce the return time under the premise of reducing the investment cost.The economic evaluation and analysis of the user-side energy storage scheme were carried out.The investment cost,operation cost,power demand management income,peak valley arbitrage income,frequency modulation service income and demand response income were analyzed respectively.Combined with the current peak valley load change curve in Jiangsu province,two kinds of energy storage income were proposed through the daily charging and discharging times of energy storage and whether or not to participate in the enterprise load curtailment service.At the same time,the total economic evaluation model of the two energy storage schemes was obtained.Taking the energy storage equipment of an enterprise as an example,the economic evaluation was carried out,and the results of income comparison under the two energy storage schemes were obtained.The research results have certain guiding significance for the current commercial investment of energy storage equipment.
