An Efficient Solar Power Generation System for Chakaria Island of Bangladesh

It is the international trend to promote renewable energy, as part of energy security as well as greenhouse gas emission reduction. Solar energy can be used to supplement the conventional energy sources predominantly in remote coastal localities of Bangladesh. Feasibility study of renewable resources of Chakaria, an off-grid remote island, is presented in this paper. Purpose of this study is to design, simulation and economic analysis of a stand-alone optimal mini-grid Solar power generation system in a remote island of Bangladesh to satisfy the energy demands as well as Greenhouse gas (GHG) reduction in a sustainable way by HOMER ENERGY software. The optimum size of different components, electrical load with a certain random variability, fraction of renewable energy, excess electricity, the performance of its different components, environmental impacts, cost of energy (COE), net present cost (NPC), annualized cost are analyzed in this paper. This proposed system can be a perfect long term solution to meet the energy demand in Chakaria island. Cost of electricity found from this simulation is 0.3362 $/kWh which is acceptable.
