An Experimental Analysis of Power Quality in Presence of Single Phase Grid Connected Photovoltaic Systems

In this paper, an experimental power quality analysis in presence of single phase grid connected PV systems is performed in a PV system installed at the Department of Electric Engineering Systems of the University of Palermo through a measurement system set up by the Authors. In particular the analysis has been carried out, focusing the attention on voltage and current distortion, as the solar radiation varies The corresponding Total Harmonic Distortions in voltage and current terms are reported and compared with the standards limits. The presence of interharmonic components is also discussed.
