Sizing Optimization of PV-Battery Hybrid for Public Lighting System

Abstract

This paper deals about sizing of hybrid renewable source application to supply power for public lighting system for entire village without connection to the electrical grid. Such hybrid renewable power systems are suitable in remote area where grid connection is unavailable or connection to grid is expensive. Hybrid system in this paper consists from photovoltaic power plant and large battery bank to storage electricity. Battery bank is supposed to be large because time when electricity is needed is completely different from time when photovoltaic power plant produce power from sun.
