Impact of Power Quality Issues in Grid Connected Photovoltaic System

Power quality in the recent decade becomes one of the key components, which impacts the economy of a country. A huge increase in the population matters the large consumption of energy, in turn, leads to equivalent power generation. To control the greenhouse emissions and the worldwide warming up due to the utilization of conventional sources, substitution can be made with the support from the alternate green energy source. Also, the performance of the electrical utility can be improved by exploiting renewable resources since conventional energy is decaying day by day. Solar energy becomes the most prominent among the renewable resources, having enormous potential across the country. Power electronic interfaces like DC-DC converter, DC-AC inverter incorporated between the source and utility provides a stable power output. This proposed paper portrays the difficulties and concerns in the deployment of solar power towards the utility/public grid integration. The permissible level of penetration, optimal planning and sizing, voltage fluctuations, associated harmonics and appropriate filters are reviewed precisely.
