The Impact of Micro-Sources on Voltage Distortions in a Power Grid

Main Article Content

Magdalena Grzymkowska, Jacek Klucznik


The increase in the number of photovoltaic (PV) systems integrated with low voltage (LV) grids has led to a great need to analyse the impact of these systems on the quality of electricity and the reliability of its supply. This paper presents and compares the energy quality requirements imposed by various countries on photovoltaic plants. Then, based on real object tests and simulation in DIgSILENT PowerFactory, the impact has been identified of insolation on the generation output, range of harmonic emissions, changes in voltage levels, and total harmonic distortion (THD) in current and voltage. The results depended on the micro-source power and location, and the grid load.
