Dynamic voltage restorer (DVR) is used to protect sensitive loads in disturbances of distribution generation (DG) system. In this paper, a variable step size incremental resistance based conductance maximum power point tracking (MPPT) technique implemented for solar photovoltaic (PV) grid connected A quality study which includes perturb & observe (P&O) MPPT comparison carried out during fault on side. At the same time, proportional integral and artificial intelligence-based fuzzy-logic controlled DVR operated injects faulted Simulation results show fuzzy logic scheme demonstrates simultaneous exchange active reactive power, less total harmonic distortion source converter (VSC) current current, fluctuation DC bus VSC, injection, fast optimum operating at unity factor. This paper aims simulating validations VSC control approach using manufacturer's PV data sheet; effectiveness proposed schemes. The whole framework simulation PV-DG model constitutes computer-aided design tool that helpful professionals who require simple, fast, accurate simulator their systems precisely.
