Effects of PV microgeneration on rural LV network voltage quality

Increase in photovoltaic (PV) systems integrated into low-voltage (LV) distribution networks has created a pressing need for analysis of the effects of these systems on power quality and supply reliability. The main aim of this study was to analyze the effects of small-scale PV-system power generation on voltage quality in a rural LV distribution network. In the analysis based on real field measurements, the numerical and graphical methods of data analysis were used. Thus, correlations between PV-system power (P(pv)) generation and voltage quality parameters in the LV-grid were examined.
