Two Stage Solar PV Based With Battery Energy Storage System for Induction Motor Drive

Abstract

Abstract: A grid-connected photovoltaic power system, or grid-connected PV system is an electricity generating solar PV system that is connected to the utility grid. A grid-connected PV system consists of solar panels, one or several inverters, a power conditioning unit and grid connection equipment. The simulation results are performed However, the availability of PV power is intermittent in nature, and hence, PV-based stand-alone systems need an energy storage element which is generally realized by utilizing a battery bank. The major challenges in designing such systems are as follows: 1) extraction of maximum power from the PV array; 2) protection of the battery from overcharge and over discharge; 3) dc to ac conversion; and 4) provision for adequate voltage boosting.  As multiple objectives are required to be satisfied, the existing schemes for stand-alone systems require a minimum of three converter stages, leading to considerable reduction in the reliability and efficiency of the system. In order to address this issue, a two-stage stand-alone scheme consisting of a novel transformer coupled dual-input converter (TCDIC) followed by a conventional full-bridge inverter is proposed grid-connected photovoltaic power system, or grid-connected PV system is an electricity generating solar PV system that is connected to the utility grid. A grid-connected PV system consists of solar panels, one or several inverters, a power conditioning unit and grid connection equipment. The proposed concept is further implemented with Grid Connection based PV System simulated using Matlab/simulink software.
