    Abstract

    The interconnection of renewable energy sources into the utility grid gives lot of issues. The important issues faced by the systems are synchronized with the utility grid, power quality, and others. The distribution static compensator (DSTATCOM) is the efficient custom power device that can resolve the power quality problems in the distribution system and interconnect the Photovoltaic (PV) system into the utility grid. The Second Order Generalized Integrator (SOGI) Phase Locked Loop (PLL)–based Unit Vector Template (UVT) control scheme is employed for extraction of reference current to generate gating signals of DSTATCOM. The proposed control algorithm is employed for compensation of current harmonics, reactive power, and voltage interruption. The dc link storage capacitor of the DSTATCOM is utilized to interconnect the PV system into the utility grid, and it is controlled by the UVT-based controller. The PV-supported DSTATCOM provides uninterrupted active and reactive power compensation when disturbances occur in the distribution system. The simulation and experimental results confirm that the proposed DSTATCOM results in purely sinusoidal grid currents with the Total Harmonic Distortion level about 1.28 %, which enhances the power quality of the interconnected PV system.
