Techno-economic analysis of solar photo-voltaic/diesel generator hybrid system using different energy storage technologies for isolated islands of India

• Optimal sizing of solar photo-voltaic/diesel generator/battery hybrid system for isolated islands India. Exclusive techno-economic investigation four different energy storage technologies the above system. Zinc bromine flow (ZBF) technology based offers highest return investment and renewable penetration with lowest simple payback period pollutant emissions. Sensitivity analysis ZBF integrated using unique three-dimensional approach. This paper exclusively investigates performance photo-voltaic (SPV)/diesel generator (DG) battery (BES) namely lead acid battery, lithium ion vanadium redox zinc Andaman & Nicobar Lakshadweep The has been performed Hybrid Optimization Model Electric Renewables (HOMER) software at Baratang Minicoy Lakshadweep, respectively, in which SPV/DG/ZBF (20 kW SPV, 7 DG, 100 kWh batteries 20 converter) found to be most viable optimized solution both locations. net present cost, levelized cost energy, operating this configuration are $23927.21, $0.167/kWh $338.20, island; $22366.64, $0.155/kWh $217.49, island. Using as baseline configuration, was extended BES evaluate parameters like investment, period, produced, emissions, etc. effectiveness is justified obtained results show value emission. Finally, sensitivity a
