Abstract Energy consumption and utilities have increased in the last two decades due to diversified applications in the field of science and engineering. Thus, energy saving have become an active research. It has become an essential criterion to take out system faults to ensure the efficient functioning of the overall system. The power quality issues concerned with voltage sag and they frequently cause serious power interruptions, if suitable care will not be taken in time. This work presents a novel photovoltaic fed Dynamic Voltage Restorer (PV-DVR) model to alleviate deep voltage sags and outages on a low voltage residential distribution system. The application of low stepup and high stepup DC–DC converters used in the existing DVR system results in high conversion loss. Moreover, two control loops are required to control the two separate converters which results in higher control complexity. Thus, in this proposed work, two port hybrid high gain buck boost converter (TPHGC) is integrated in the existing PV-DVR system. Two converters used in the existing system are replaced with single battery charging bidirectional converter. Simulation results are presented to validate the advantage of the proposed system.
