Comparative study of Different Topologies of Solar Photovoltaic fed Impedance-Source Inverter based Dynamic Voltage Restorer

Abstract

All customers require quality voltage, quality current and quality power from the utility, but usage of nonlinear loads generates voltage sag, swell and harmonics. This work examines the solar energy based various topologies like 3-Leg, 4-Leg, and 6-Leg Dynamic Voltage Restorer (DVR) for minimizing the voltage swell. To get most prominent power from the solar system Perturb & Observe (P&O) scheme is also used. The most famous topologies are approved utilizing MATLAB/SIMULINK programming to limiting voltage swell. The gained results are comparable nonetheless even possibly better in 6-leg PV-ZSI-DVR diverged from 3-leg and 4-leg PV-ZSI based DVRs.
