Electrification of rural islands is still a major challenge for many countries due to the inadequate and inchoate distribution of fossil fuels in conventional grid system. Even if these problems are eliminated, the high electricity cost makes rural people ineligible for electricity services. In addition to tackling environmental pollution, microgrids (MG) could be the appropriate solution to reduce these economic barriers. Aiming to mitigate the impediment of rural electrification, this study proposes a hybrid microgrid consists of renewable energy sources, natural gas generator, battery storage, and electric vehicle charging station where a case study is performed with and without wind turbine as a renewable energy source. The MG is simulated for two coastal areas of Bangladesh, and sensitivity analysis has taken place by varying the load demand. MG without wind energy is found more affordable than MG with wind energy. The winning case configuration estimated the cost of energy of 0.157$ and the carbon dioxide (CO ₂ ) emission of 6666.47 kg/y, which is a betimes step in ensuring pollution-free power supply as well as electrification in powerless areas. The results lead to the conclusion that the proposed model can provide affordable alongside eco-friendly electrification.

基于可再生能源的混合微电网，实现经济有效的沿海电气化


由于传统电网系统中化石燃料的分布不充分且不成熟，农村岛屿的电气化仍然是许多国家面临的重大挑战。即使这些问题得到解决，高昂的电费也使农村人口没有资格获得电力服务。除了解决环境污染之外，微电网（MG）可能是减少这些经济障碍的适当解决方案。为了减轻农村电气化的障碍，本研究提出了一种由可再生能源、天然气发电机、电池存储器和电动汽车充电站组成的混合微电网，并在使用和不使用风力涡轮机作为可再生能源的情况下进行了案例研究。 MG 对孟加拉国的两个沿海地区进行了模拟，并通过改变负载需求进行了敏感性分析。不带风能的 MG 比带风能的 MG 更便宜。获胜案例配置预计能源成本为0.157美元，二氧化碳（CO ₂ ）排放量为6666.47千克/年，这对于确保无污染供电和无电地区电气化来说是一个及时的步骤。结果得出的结论是，所提出的模型可以提供经济实惠且环保的电气化。
