The purpose of my thesis is to present the effect of the weather dependent energy production of renewable energy sources (wind and photovoltaic) by using optimal power flow (OPF) simulations.
I expand my theme from basic information, therefore in the first part of my work I will give a short outlook about the power system and the actuality of renewable energy sources. I shall highlight the importance, complexity, the different types of OPF and the several methods of calculation applied by it.
Following the analysis of the DIgSILENT Power Factory as a software, which could run optimal power flow calculations I shall present different static test options of the program on a 3 bus network. By using the acquired knowledge, I came up with a dynamic method to visualize the effects of RES’s production.
The test method was used on a model representing the energy mix of EU-28 and on the distribution network of Mosonmagyaróvár. Finally, I shall summarize the results of the calculations and the technical challenges as well as the awaiting possibities.
