Abstract

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
