The study was aimed at satisfying the energy demand of the Patani Island community (5°13’43” N, 6°11’29” E). A mathematical model was developed to describe the integrated system, and a genetic algorithm was employed to optimize the allocation of energy demand, energy generation, and energy storage. Economic models were also formulated to determine the techno-economic feasibility of the hybrid plant. The mathematical model, optimisation scheme, and analysis were implemented in HOMER® and MATLAB®, while the results were post-processed using MS Excel®. The optimal results indicate that the peak rated power of PV, WT, and Biomass needed to meet the island’s energy demand are 0.218 MW, 236 MW, and 0.100 MW, respectively. The energy demand by Patani Island is 43662 MWh/year while the total energy generated by the integrated renewable energy system is 43623.845 MWh/year, the minimum storage capacity for both battery and hydrogen was estimated to be 138.38 MWh, the levelized cost of energy (LCOE) was calculated to be $0.321 per kWh (₦482/kWh), and the loss of load probability (LLP) of the proposed energy system was estimated at 0.11. The present study demonstrates that an integrated renewable energy system can be a practical and applicable approach to electrifying Patani Island.
