基于CES效用函数的温度敏感负荷替代弹性计算
Calculation of Substitution Elasticity of Temperature-sensitive Load Based on CES Utility Function
摘要
Abstract
In this paper,a method for calculating the electricity demand elasticity of temperature-sensitive load is pro?posed. Firstly,according to the utility theory in economics,the total utility functions of three kinds of"commodity",i. e.,the electricity consumption quantities in the peak,flat and valley periods,are determined. On the basis of total utili?ty function,the electricity demand models in the peak,flat and valley periods are determined based on the consumer equilibrium conditions in economics. Then,based on these models,the substitution relationship of electricity consump?tion quantity between peak and flat periods and that between valley and flat periods are analyzed,thus the calculation methods for the substitution elasticity between peak and flat periods and that between valley and flat periods are deter?mined. Finally,a numerical example is used to verify the validity of the proposed method. This calculation method pro?vides an accurate and effective method for the calculation of the substitution elasticity of temperature-sensitive load in the electricity demand response based on electricity price,which lays a foundation for the load forecasting,potential analysis for users'energy-saving and evaluation on the benefit of multi-agent.关键词
