Experimental Investigation of Harmonics in a Grid-Tied Solar Photovoltaic System

Megha Khatri, Atul Kumar

Abstract


The power quality issues in the grid tied solar photovoltaic system are important to address to know the actual power production and consumption in the existing system. This paper investigates the presence of voltage and current harmonics due to the linear, nonlinear loads and the reactive power transferred between plant, grid and load. The digital power analyzers are kept in the system to know the amount of power import and export between the plant and grid, so as to serve the load. In order to control the effect of harmonics a compensator in incorporated in the phase locked loop of the inverter as well as a power quality conditioner is connected at the point of common coupling. It has been found that by switching the compensator unit, the quality of power and power factor of the system gets improved and it also reduces the export of reactive power to the load so as to obtain the reliable and efficient operation of the grid tied solar photovoltaic system.
