A PV-Wind-Diesel-Battery Hybrid Off-Grid Microgrid for Rohingya Refugee Camp at Bhasan Char of Bangladesh

This paper studied the potentiality of an off-grid hybrid microgrid for harnessing efficient energy at Rohingya refugee camp in Bhasan Char, a small Island in the southern part under Noakhali District of Bangladesh. In order to choose the most appropriate microgrid configurations, six microgrid architectures that include solar PV, wind turbines, diesel generators, converters, and batteries have been rated. By evaluating the performance these six different combinations an optimal configuration has been determined following a systematic approach considering distinct parameters and different components in a group. This study is enhanced by many performance indicators, such as per unit cost of energy, capital cost, renewable energy fraction, emission of CO 2 , excess electricity, unmet load etc. According to evaluation, this paper recommends PV-Wind-Diesel-Battery-Converter as an ideal hybrid microgrid system for the policymakers for the selected area. For the most feasible microgrid case, in this paper, the electrical, financial, emissions and sensitivity analysis have been conducted. This hypothetical approach can help researchers and decision-makers to plan microgrids more effectively based on accessible local energy resources.
