中文摘要:

      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。

英文摘要:

      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 stor-age 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 of peakanalyses the econmic benefit, calculates the price difference- valley which can bring benefits and the dynamic paybackperiod under current electricity price policy. Finally, the prospect of energy storage technology is forecasted.
