Abstract

The goal of this paper is to investigate the correlation between power system load and air temperature in Republic of Macedonia. Power system load hourly values (8760 per year) for year 2014 and 2015 are used as input data. In absence of hourly values for air temperature in Republic of Macedonia, data from internet is used for minimal, average and maximum air temperature for city of Skopje for each day of year 2014 and 2015. In order to have equal data for stochastic variables (3x730 values), minimum, average and maximum power system load is calculated for each day of year 2014 and 2015. Linear and nonlinear correlation coefficients are calculated between minimum, average and maximum load as dependant variables and minimum, average and maximum air temperature as independent variables. Results have shown very strong dependence between power system load and air temperature. Procedure of linear and nonlinear regression is performed in the paper for determining the functions of variation between three typical loads and appropriate air temperatures. Several useful conclusions and further work possibilities about this matter are presented at the end of the paper.
