Most of the economies are emerging with the growth in the renewable energy system. A solar photovoltaic system is one of the good sources of energy among them which provides clean and green energy. As it adds less pollution to the environment and hence advancement in technology of renewable energy system adds great effect on the environmental preservation. Recent developments in solar technology, such as lower panel costs, more efficiency, and better tracking schemes, have given the industry a major push that has led to widespread PV penetration. However, there also exists another face of this growing trend which needs to be addressed for successful and effective utilization of these integrated systems. The temperature and irradiance affect the power output of PV panels significantly. For a particular irradiance and temperature, the maximum power available at the PV panel is associated with a unique point on the PV and IV curve. PV module requires power electronics converters as an interface in between PV panels and load for getting maximum power point on PV curve. In addition to all the PV advantages there have been rising issues also like deterioration in system reliability, transient stability, power quality, etc. In general, PV system interfacing is carried through a current controlled voltage source inverter (VSI) with frequent switching on and off. Also, the non-linear loads mainly draw distorted currents and hence generates large amount of harmonics in the system. Another important concern is that sudden tripping of PV system may lead to voltage transients and other ill-effects. Thus it can be seen that PV penetration leads to a number of PQ issues which may cause serious damage if not addressed properly.
