In order to GRASP the influence of temperature on the power load in Changsha

this paper comprehensively analyzes the relationship between conditioning load and temperature of Changsha power grid from 2011 to 2017.The proportion of the summer cooling load and the winter heating load in the overall power load since the "12th Five-Year Plan" is statistically analyzed.Based on nonlinear regression

the correlation analysis between air conditioning load and the daily maximum temperature for the past five years is made

and the effect of temperature changes on air conditioning load is concluded.Moreover

the impact of high and low temperature duration on the load is analyzed.
