An efficient interleaved converter based PV-DVR for improving voltage quality

This paper presents a novel photovoltaic fed Dynamic Voltage Restorer (PV-DVR) is proposed to moderate deep voltage sags, voltage swells and power on a low voltage residential supply arrangement for the duration of both day time and night time. During extra voltage regulation, the proposed PV-DVR reduce the power conservation from the utility grid by disconnect the utility grid from the load in the semiconductor switch. As the PV arrangement generates average or same power to the critical load require through the day time. But the decrease of power conservation is permanently needed for the decrease of panel tariff and over all warm gas. Extra they manage of low step-up DC–DC converter. Considered interleaved high step up DC-DC converter with PI controller algorithm eliminates the drawback of conventional PV based DVR by tracking perturb & observe maximum power point( MPPT) of the photo voltaic array. Simulation and experimental results are presented to validate the improvement of the proposed system.
