Problematika připojitelnosti FV elektráren do distribuční soustavy

Abstract

This bachelor thesis deals with the issue of connectivity of photovoltaic power plants to the distribution system. The introductory part describes the structure of the power system, the legislative and regulatory framework, and the process of connecting generation units to the grid. Subsequently, photovoltaic sources are characterized, including their operating principles, electrical properties, and impacts on the distribution network. The practical part focuses on a model example of connecting a 6 MWp photovoltaic power plant to a 22 kV distribution network. Using the DNCalc simulation tool, the impact of the source on voltage conditions and loading of network elements is analyzed. The results are used to assess compliance with technical connection requirements and to identify potential limitations.
