An efficient solar-diesel hybrid power generation system for Maheshkhali Island of Bangladesh

It is the international trend to promote renewable energy, as part of energy security as well as greenhouse gas emission reduction. Wind and solar energies can be used to supplement the conventional energy sources predominantly in remote coastal localities of Bangladesh. Feasibility study of renewable resources of Maheshkhali, 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-Diesel hybrid power generation system in a remote island of Bangladesh to satisfy the energy demands in a sustainable way by HOMER ENERGY software. Two diesel generator are added to ensure uninterrupted power supply due to the intermittent nature of renewable resources. Optimum size of different components, electrical load with a certain random variability, fraction of renewable energy, excess electricity, performance of its different components, environmental impacts, cost of energy (COE), net present cost (NPC), annualized cost are analyzed in this paper.
