A Case Study on Efficient Grid Connected Hybrid Energy System for Rohingya Refugees

Abstract

In this study, a grid connected hybrid power system is designed using renewable resources solar and wind energy to provide electricity facility in Rohingya refugees camps at Teknaf Bangladesh. Hybrid optimization Model for Electric Renewables (HOMER) software is used to analysis the entire system cost and the power system’s potentiality and sustainability in the project place. Solar radiation, Temperature and wind speed data is collected from National Aeronautics and Space Administration (NASA) surface meteorology and Solar Energy (SSE) archives which needs for system feasibility analysis. In this paper 1.5 MW solar wind grid connected hybrid system is designed where 62% electricity are renewable fraction and remaining is consumed from grid. This system met an average 5.4 MW load per day at a cost rate of $ 0.12/kWh and the total net present cost of this system is $ 2605521. This is a reliable arrangement, because the lack of electricity at the time of the peak load is filled in from the grid and during off-peak hours the additional power from the renewable energy source supplied to grid. It is a vital energy solution for refugee camps which locate in rural areas.
