Analysis of Voltage Sag and THD Using Dynamic Voltage Restorer

Despite recent developments in clean energy, microgrid advancements, and power electronics, the present power system continues to face plenty of issues arising from its integration. Interference with other components of the system can create a change in input voltage, which can harm sensitive equipment. Harmonics, voltage sag, & swell themselves can harm the sensitive machinery. A Dynamic Voltage Restorer (DVR) is an equipment that is extensively used in distribution grids to address sag, swell and harmonic issues. Simultaneous simulations of the recommended DVR-based approach in MATLAB/Simulink were carried out to show its efficacy in normalizing voltage profile and harmonics.
