Description
Summary:Nowadays Photovoltaic systems have become one of the dominant renewable energy sources for generating electricity in the world. The photovoltaic system is a clean, friendly and non-polluting energy source with the reduced carbon dioxide (CO2) emission, when compared with the conventional energy sources, which pollutes the environment and makes it hazardous to human health. However, the output wave forms of Voltage and Current generated by the Photovoltaic systems produce harmonics. This is due to the power electronic converters and the non-linear loads connected to the PV systems. In this paper, we present experimental results and analysis for an interactive standalone Photovoltaic system connected with different linear and non-linear loads. The experiment was performed with HIOKI 3196 power quality analyzer. The percentage of the total harmonics distortion (THD) of the Voltage (THDV) and Current (THDI) have been studied in this paper. Results of the THD are presented and compared with IEEE 519-1992 standard.
