摘要: 尖峰电价可以驱动用户主动减少高峰用电负荷并自愿参与需求响应。以江苏省3年的第二产业负荷数据为基础,运用数理统计方法实证研究了尖峰负荷价格弹性的时间特征,给出了尖峰电价政策福利函数,并根据不同弹性下需求响应的程度对尖峰电价政策的福利效应进行了分析和估算。结果表明:尖峰电价可以使社会净福利显著增加,但各月和各时段增幅差异较大。按照社会最大化原则,执行尖峰电价政策及尖峰价格浮动幅度,应依据负荷价格弹性季节和时段特性有选择性地确定。

Abstract: The peak electricity price can drive customers to actively reduce the consumption of peak electricity load and voluntarily participate in demand response. Based on the secondary industry load data of Jiangsu province in latest three years, This paper studies the time characteristics of price elasticity of peak load with mathematical statistics method, presents the peak price policy benefit function, and analyzes the welfare effects of peak price policy in different degrees of demand response under different elasticity. The result suggests that the peak electricity price can remarkably increase the net social welfare, but the growth of different months and periods varies greatly. In accordance with the principle of social maximization, the policy and floating range of the peak electricity price should be determined by seasonal and time characteristics of load price elasticity.

Key words: electric power, peak electricity price, load price elasticity, time characteristics, welfare effects, demand response
