Modelling and cost analysis of hybrid energy system for St. Martin Island using HOMER

The amount of the conventional energy sources is decreasing day by day on earth. To avoid the energy crisis, the incorporation of the use of renewable energy sources is highly required. For decentralized or remote areas, where grid connection is almost not possible, renewable energy generation system coupled with diesel engines can be a reliable and optimized source of energy. In this study, a remote island of Bangladesh, St. Martin has been taken for the discussion of the cost optimization analysis of a hybrid energy generation system. St. Martin´s Island is about 9 km away from the tip of the Cox´s Bazar-Teknaf peninsula. For the geographical location of this island, it is impossible to provide grid connection to there. An effort has been made to design a hybrid electricity generation system for a small group of people of this island. This hybrid system is combined with solar PV, wind turbine and diesel generator. Here, HOMER is used to examine the most cost effective configurations among a set of systems for electricity requirement of 53 KWh/day primary load with 10 kW peak load.
