The energy crisis is due to the limited resources and increased consumption. However with the advent of renewable energy this energy crisis solved to a great extends. Poor distribution system is one of the reasons for such energy crisis. The poor distribution is due to the wide use of non linear loads because non linear load is responsible for the generation of harmonics and thereby it affects the power quality of the system. The unexpected occurring of power quality issues such as voltage sag, voltage swell, transients, flickering, etc... Affects the quality of power delivered to the distribution section of power system. So it is important to eliminate or mitigate this power quality issues for improving the power quality. In this paper, power conditioning of power system by Dynamic Voltage Restorer (DVR) with solar PV- battery storage system is explained to mitigate mainly voltage sag and voltage swell issues. Power conditioner consists of the novel integration of solar PV, DC-DC boost converter and DVR.
