Investigation of the voltage quality at PCC of grid connected PV system

In this paper, we present and discuss the behavior of the voltage in the Algerian Low-Voltage distribution network and the influence of the PV generation. This intermittent availability characteristic will have a local impact on the power quality. Hence, a statistical analysis of the voltage characteristics is shows to evaluation the grid at Point of Common Coupling (PCC) according to the EN 50160 and IEC 61000-2-2 standards. The voltage variation, unbalance, flicker severity, total and individual harmonic are presented. It has been found that the voltage at the PCC is in accordance with standards requirement.
