Analysis on the factors of daily electricity sales of urban and rural residents in Hunan province

It’s of practical significance to explore the internal law of the fluctuation of the daily electricity sales of the urban and rural residents in Hunan province for the electricity planning and resource allocation in Hunan province. In this paper, after considering the economic meaning of electricity sales changes, a variety of factors were selected to influence the electricity sales of urban and rural residents in Hunan province, and the monthly residential electricity demand model from 2014 to 2019 was constructed, and the gradual regression was carried out. The results show that the per capita disposable monthly income (dpi ) and non-comfortable days (ncd ) have significant impacts on the electricity sales of urban and rural residents. And for every 1% increase in dpi or for each additional day of non-comfort days per month, the domestic electricity sales of urban and rural residents will increase by 0.49% or 0.01%. In addition, under high temperature and low temperature conditions, the influence of precipitation presents asymmetric characteristics.
