Abstract:The electrical energy system is transforming worldwide into smart grids. The vision of smart grid
demands a cutting edge technology for integrating the different renewable energy sources. Integration of
renewable such as solar photovoltaic (PV) pose various power quality problems in the system, one such
problem is harmonics generation. Harmonics are generated by the associated power electronics based
interfacing devices. Moreover the load connected to the distribution system is nonlinear and harmonic is rich in
nature. Therefore, a lot of harmonics is injected into the system either from the source or from the load ends and
affects the performance of power system. Harmonic distortions create excessive power loss and abnormal
temperature rise, results the overheating of transformer, overheating of neutral conductor and malfunction of
protective devices, which endangers the stability and reliability of the system. The smart distribution grid must
absorb such concerns through.......
