Analysis of Temperature Changes on Electricity Consumption in Fars Province

Abstract

Climate change is one of the factors that effects on electricity consumption behavior and changes in load of the network. Meanwhile, temperature is the most important factor because the use of heating and cooling devices in large scale. In this paper, the effects of air temperature fluctuations on electricity consumption with the help of temperature coefficient and Weighted-population index are brought into consideration. Then, the network load dependency from air temperature changing is analyzed. After that, through applying HDD and CDD indexes load sensitivity to air temperature in cooling and heating period of the year is calculated. Analyses of elasticity coefficient of load and air temperature are the last step in monitoring the fluctuations in electricity consumption in hot and cold weather. Also, comparing seasonal temperature variations with load table and temperature correlation coefficients show very close relationship between these two. Correlation coefficient is approximately 0.90 in several months of the year.
