摘　　要：浙江省电力负荷快速增长,峰谷差呈逐年上升趋势,高峰负荷持续时间比较短暂。储能技术迅速发展、成本不断下降,储能逐渐成为缩小峰谷差的重要措施。针对浙江电网的实际情况,建立了电化学储能成本模型和收益模型,对储能的经济效益进行分析,得到能产生利润的峰谷电价差和目前电价政策下的动态投资回收期,最后对储能技术的前景进行展望。The electric load of Zhejiang Province is growing rapidly,and peak-valley difference is increasing by years.The duration of peak load only lasts for a short time.As energy storage technology is developing rapidly and the cost of it is falling,energy storage gradually becomes an important measure of reducing peak-valley difference.Aiming at the reality of Zhejiang power grid,the costbenefit analysis of electrochemical energy storage is modelled.This model analyses the econmic benefit,calculates the price difference of peak-valley which can bring benefits and the dynamic payback period under current electricity price policy.Finally,the prospect of energy storage technology is forecasted.
