Feasibility of FSPV-Grid Tied System in Urban Regions of Chhattisgarh State in India

Abstract

This study presents a novel generation theory based on FSPV system together with grid integration in Chhattisgarh state. In this study four regions mainly two industries and two local loads have been chosen to evaluate the results. There is availability of nearby water sources at the selected sites. The technical, economical and environmental aspects of a proposed FSPV-grid tied system is analyzed in the same selected regions of Chhattisgarh and the results are compared with an existing grid-only system. The entire system of four major sites in the state are simulated using HOMER energy, powered by the National Renewable Energy Laboratory (NREL), United States. At the moment, all of the selected systems are powered by the grid-only system, and data has been collected for the same. The results of HOMER energy are further classified based on economic parameters such as NPC, LCOE, operating cost, system cost and paybacks. The second category includes technical parameters such as production proportion whereas, the third category includes environmental parameters of pollutants and water saving. The obtained results show that the FSPV-grid system as compared to grid-only system's NPC is reduced to 27%, 7.03%, 10.76%, 12.13%, LCOE is reduced to 69%, 27.8%, 44%, 44.6%, with paybacks of 10.11 years, 12.28 years, 11.99 years, and 12.21 years and IRRs of 8.8%, 7.7%, 8%, 7.7% respectively by following the production proportions of 77.7% and 22.3%, 54.2% and 45.8%, 65.2% and 34.8%, and 65% and 35% from FSPV and grid system, Also, CO2 emissions were reduced by 44.6%, 38.06%, 40.62%, and 41.23% compared to the gridonly system for all four selected sites in this study, which can help the attached industries and local loads gain carbon credit points.
