Sažetak
Joining the European Union (EU), Croatia has committed the obligation to forefeel the goals according to the share of renewable energy sources (RES) in the electricity production, in order to reduce greenhouse gas emissions. The goal is to achieve a 20% share of electricity production from RES in the total electricity production by 2020. Technologies garnering the most attention are solar and wind energy sources. The aim of this work is to perform linear regression and correlation between solar radiation, wind speed, air temperature and electricity demand of the Dubrovnik region in order to obtain results that would help in system energy planning with a high share of RES in the electricity production. This region has a good potential in use of solar radiation, as well as the wind power, meaning these technologies are the best choices to achieve the share of RES in electricity production. All of the data are collected for consecutive three year period, years 2012, 2013 and 2014, in the 10 minutes time step. Results of the correlation of each of the parameters individually in between the years show slightly variations between the distributions, providing representative linear relation in between the years for all the data, except the wind speed data. Correlations are also done between all of the parameters for each year separately, based on the mean monthly values, resulting in good relation with negative correlation between solar radiation and wind speed, as well as good relation with positive correlation between solar radiation and electricity demand. The same correlations are done in the 10 minutes time step and including time system delay. The results indicate significant decrease in correlation coefficient value and it is less possible that they can be pronounced with linear regression line.
