The work discusses a setup where two feeder lines are connected to a point of common coupling (PCC) bus and a voltage source. Feeder line 2 incorporates a DVR and a three-phase programmable voltage source to supply power to a non-linear load, while feeder line 1 only has a resistive load. And feeder two is connected to non- linear load. Power quality issues such as voltage sag, swell, Interruption, and Harmonic generation are achieved through three phases Programmable voltage source connected to feeder line two. We analyze the effects of the voltage sag, swell, interruption, and harmonic at the load side of feeder line 1 and along with feeder line 2. By employing the DVR, power quality issues arising from voltage sag, swell, interruption, and harmonic in the system can be mitigated by DVR. This utilization of a custom power device leads to an improved voltage profile and addresses the poor power quality of the system. The analysis also includes an assessment of the improvement in total harmonic distortion (THD).
