Grid Integration of PV System: Issues, Challenges and Opportunities

The constant increase in electricity demand, as well as the depletion of fossil resources, has prompted research into alternate energy sources. Solar photovoltaic (PV) systems are gaining popularity in the renewable energy area due to their size, installation, and ability to operate both off and on the grid. As a result, solar roof tops with grid integration are gaining popularity in India. Many FACT devices must be interfaced with power electronics converters in order to integrate such renewable energy sources with the grid. Power quality requirements such as voltage imbalance, voltage regulation, power factor, harmonics, and others have become more significant since the development of power electronics switching devices. Overall, the distributed generation option increases power quality concerns when integrated with the grid. This paper focuses on opportunities, challenges and issues related to the grid integration of solar PV systems.
