Optimal planning of off-grid solar-wind-tidal hybrid energy system for sandwip island of Bangladesh

Electricity is the base of development of a country and the need of electricity is increasing every moment. Developing countries like Bangladesh are facing severe energy crisis. Most of the power generation in Bangladesh is based on natural gas and fossil fuel which makes it hard to meet the increasing demand. As a tropical country, Bangladesh is blessed with renewable energy resources all over the country and it is high time to utilize these resources to generate electricity. So a hybrid power system utilizing renewable energy resources can be a partial solution to the energy crisis. Having a large coastal area containing tidal, wind and solar resources, a hybrid system, utilizing all these resources can be a better option to solve energy crisis in coastal area of Bangladesh. This paper proposes a detail design and cost analysis of a hybrid power system utilizing solar, wind and tidal resources with a diesel generator backup and using the pricing of the available batteries and Solar Panels in the Sandwip island of Bangladesh.
