Abstract

All customers requires quality voltage, quality current  and quality power from the utility, but usage of nonlinear loads, generates voltage sag, swell and harmonics. This paper discusses the renewable energy (RE) fed different topologies such as, Three-Leg (3-L), Four-Leg (4-L), and Six-Leg (6-L) Dynamic Voltage Restorer (DVR) for control the voltage swell. Perturb & Observe (P&O) technique is also utilized to get maximum power. The most popular topologies are validated using MATLAB/SIMULINK software for minimize voltage swell. The acquired results are equivalent however even marginally better in six-leg PV-ZSI-DVR contrasted with three-leg and four-leg PV-ZSI based DVRs.
