Abstract

This bachelor thesis deals with the analysis of electricity production by a photovoltaic power plant located on the VŠB-TUO campus and its subsequent computer simulation. Given the massive development of renewable energy sources, accurate production prediction is crucial for grid stability and operational economics. The aim of the thesis is to verify the accuracy of freely available simulation tools (PVGIS and PVWatts) by comparing theoretical results with real operational data from inverters from the year 2022. The thesis analyzes selected reference days across seasons and the annual energy balance in detail using statistical methods (RMSE, MAE). The results demonstrate the high reliability of the PVGIS model using the SARAH3 satellite database. Furthermore, the thesis reveals and proves that the observed deviations in the annual balance were not caused by simulation software errors, but by the incompleteness of the real dataset due to communication dropouts of the monitoring system. The outputs of the thesis thus serve as a verification of simulation models and also as a basis for optimizing the monitoring of the university's local distribution system.
