Evaluating the Balancing Properties of Wind and Solar PV Production

This research evaluates how wind and solar PV balance together. Increasing the share of sto-chastic renewable energy production in electricity and hot turning reserve deficit are welcome compensation issues. This research used weather station data from an open seashore for the last 10 years, 2014-2023, on the Estonian island Saaremaa's west coast to evaluate yearly fluctuations. We use the indicator demand cover factor to estimate the coincidence of wind generation and PV solar electricity. For clarity, the initial data was prepared by assuming equality of production and consumption annual data by scaling the obtained data. The study demonstrates that the best compensating possibilities are the share of wind generation and solar PV electricity mix, respec-tively, equal to 0.7/ 0,3 and 0.8/0.2, reaching the demand cover factor of 0.62. The article evaluates the demand cover factor's dependence on increased production compared to consumption. The article uses different batteries to research the influence of these demand cover factors. Further-more, this research makes a significant contribution by showcasing - how to turn weather station data into real wind generator and PV panel production data.
