Feasibility Analysis of Standalone Hybrid Renewable Energy System for Kiltan Island in India

Abstract

AbstractThe net present cost (NPC) and the cost of energy (COE) are very high in the remote islands because energy is mainly generated from diesel generators. Pollution is also increasing due to the usage of diesel generators. So, the objective in this work is to minimize the NPC, COE, and pollution by using renewable energy sources such as solar and wind in addition to diesel. Kiltan Island of Union Territory of Lakshadweep in India has been considered for the study. The average wind speed and average daily radiation at Kiltan Island are 5.51 m/s and 5.76 kWh/m2/day respectively. The modeling, simulation, and optimization have been performed by Hybrid Optimization Model for Electric Renewable (HOMER) software. The model that gives an optimal solution includes Diesel-PV-Battery. This model gives the least NPC and COE. For sensitivity analysis, the wind speed (m/s) and the fuel rate ($) have been considered as sensitivity variables. The optimal system is obtained for the sensitivity variable of 5.21 m/s of wind speed and 1$/L of diesel price. This optimal system also reduces pollution by 90%.KeywordsOptimal systemNet Present Cost (NPC)Cost of Energy (COE)Renewable energyHOMER
