Solar PV and Battery Assisted Isolated Power Supply Control and Implementation

Abstract

Considering electricity is such an essential component of human life, it is imperative to develop systems that can generate electricity even in the most remote locations. As a result, the goal of this paper is to investigate an independent solar photovoltaic system with battery storage. For the purpose of wringing the most amount of power out of the nonlinear PV source, a boost converter equipped with MPPT tracking is used. The voltage of a battery is maintained within a predetermined range by virtue of its design, which takes into account fluctuations in the amount of solar irradiation as well as the load. The battery is designed to both store and release power in the event that there is an abundance of either. An interface between the load and the battery is provided by a DC-DC bidirectional converter that uses close loop control as its foundation. A solar power generation system with 1.2 kilowatts of capacity has been designed and developed. The design analysis and the results of the hardware-in-the-loop simulation for the suggested standalone system are presented in this paper.
