An Efficient Solar-Wind-Diesel-Battery Hybrid Power System for St. Martin Island of Bangladesh

Md. Habib Ullah

Abstract


St. Martin’s island is a small island in the Bay of Bengal about 17 km far from the main land of Bangladesh. Nearly6000 inhabitants live there and fishing is their primary livelihood and as a tourist spot there are many hotels and rest houses. Since the island is far away from the main landgrid connection is almost impossible even in future due to its geographical position. However, the electricity demand is partly fulfilled by stand-alone diesel generators. In this study, an attempt has been made to model a hybrid electricity generation system for a small community of the island. This system incorporates a combination of solar PV, wind turbine, battery and diesel generator. HOMER, software for optimization of renewable based hybrid systems, has been used to find out the best technically viable renewable based energy efficient system for 100 households and 10 shops. Sensitivity analysis is also done to see the impact of solar insolation, PV investment cost, wind speed and diesel fuel price on the optimum result. This system can reduce CO2 emission by about14 tons per year compared to diesel generator only.
