Abstract

In general, the power quality analysis is a very complex issue and it requires a long-term measurement in real distribution networks. Moreover, the voltage has to be within specific voltage tolerance for the low-voltage distribution network. In this paper the measurement of the low-voltage network after the connection of a small photovoltaic power plant is evaluated. Therefore, the influence on the changes of the voltage, flicker and total harmonic distortion by connected power plant under different operating states is described in the paper. The main task of the article is to present the results of the voltage quality measurements carried out in low-voltage distribution network.
