Utility Interfaced SolarElectrification And Indian Rural Society: A Case Study

Abstract

This paper presents a PV- grid/ DG hybrid energy system for a remote village in Jharkhand, a state in India. The hybrid system designed for rural home for 1kW load power sharing between PV-grid/ DG sources and optimize the cost of electricity against maximum household loads of 2000Wh/day. An PV inverter has been designed to supplement the load power to reduce the quantum of power to be drawn from grid sources. A prototype module has resulted in an optimal yield leading to an average monthly power sharing of 50% by PV with grid/DG over a period of one year. The objective is to meet the critical power requirement of household as a primary power source from PV and to draw power from the grid /diesel fueled-engine generator for a short period of time during peak load to achieve the optimum point of operation as well as to get the sustainable power for 24x7 days .
