Distributed generation (DG) has many uses in commercial and industrial field depends on energy uses such as renewable and non-renewable energy sources. But nowadays it is broadly used with wind and solar power. The main motto behind this is to provide a system which is environmental friendly i. e. greenhouse effect, carbon footprint reduction and limited renewable energy sources which increase the cost of fuels in today's scenario. . In photovoltaic (PV) the fluctuation of real power and reactive power is not easily controlled and results give unstable system. The variation in voltage also gives the tripping of PV unit during disturbance which is a large disadvantage of distribution system.
