【摘要】：提出了一种适用于温度敏感型负荷的电力需求弹性的计算方法。首先根据经济学中的效用理论确定3种"商品"即峰、平、谷时段用电量的总效用函数。在总效用函数的基础上,基于经济学中的消费者均衡条件,确定峰、平、谷电量需求模型;然后基于此模型,分析峰、平时段用电量的替代关系和谷、平电量的替代关系,进而确定峰、平时段替代弹性和谷、平时段替代弹性的计算方法;最后用算例验证该方法的有效性。该计算方法为基于电价的电力需求响应中温度敏感负荷的替代弹性计算提供了一种准确有效的方法,为负荷预测、用户节电潜力分析及多主体效益评估奠定了基础。
[Abstract]:A method for calculating the elasticity of power demand for temperature sensitive load is presented.Firstly, according to the utility theory in economics, the total utility function of electricity consumption in the period of peak, level and valley is determined.On the basis of the total utility function, based on the consumer equilibrium conditions in economics, the peak, flat and valley electricity demand model is determined. Then, based on this model, the substitution relationship between peak and normal period electricity consumption and the substitution relationship between valley and average electricity consumption are analyzed.Finally, the calculation method of replacing elasticity with peak, normal segment and valley is determined. Finally, the validity of this method is verified by an example.This method provides an accurate and effective method for the elastic calculation of the temperature-sensitive load in electricity demand response based on electricity price, and lays a foundation for load forecasting, potential analysis of power saving and multi-agent benefit evaluation.
