Power Quality Monitoring of Rooftop Photovoltaic Penetration Level on Low Voltage System

This article presents an analysis of voltage and current harmonics at the common point of connection (PCC) of the first practical grid connected photovoltaic system in Algeria installed in 2004, The analysis is carried out using a Chauvin Arnoux CA8336. The current and voltage sensors are connected to the output of an inverter, PCC, and the load phase respectively. The results showed that the percentage of PV power penetration compared to the rated power of the inverter and the type of load connected to the PCC affected the current and voltage harmonics.
