Photovoltaic system integrated DSTATCOM with modified UVT control scheme for harmonics and neutral current elimination

Abstract

newline Electric power distribution system is an intermediate through which power is distributed to the end users. Power electronic loads connected to the distribution system draw non-sinusoidal current from the mains, degrading the power quality by causing harmonic distortion. This thesis mainly focuses on compensation of current based distortions due to the presence of nonlinear newlineloads in the power distribution system. The Distributed Static Compensator (DSTATCOM) is the efficient custom power device that can resolve the power quality problems in the distribution system. However, this conventional DSTATCOM does not offer continuous compensation when nonlinear loads are connected permanently to the power distribution system. Therefore, this newlinethesis proposes a solution to provide continuous compensation by means of Photovoltaic (PV) array and battery storage unit. 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 DSTATCOM interconnects the PV system into the newlineutility grid with enhancement the power quality. newline
