Abstract

This study proposes an optimal design approach, based on the Pelican Optimization Algorithm (POA), to configure the optimal sizing of design variables on an islanded microgrid: photovoltaic (PV) modules, wind turbines (WT), diesel generators (DG), and batteries in Kutubdia, Bangladesh based on optimal life cycle cost (LCC) and cost of energy (COE). Additionally, the economic analysis of three independent battery technologies, notably lead acid, lithium-ion, and nickel-iron are carried out to find the economically feasible technology, to ensure uninterrupted power supply. Moreover, reliability and sensitivity analyses of the optimized microgrid using POA were conducted for various reliability indices and variable interest rates. Results show that proposed POA method provides the optimal island microgrid configuration with lead acid (LA) batteries (PV/WT/LA/DG) based on a minimum LCC of $8334901, COE of 0.1080$/KWh and greenhouse gas emission amount of 19664 kgs/year. Furthermore, the outcomes generated by the POA are compared with genetic algorithm, particle swarm optimization, moth flame optimization algorithm, whale optimization algorithm and grey wolf optimization. It is found that POA method achieves more competitive results compared to other optimization techniques due to its ability to adjust parameters, fast convergence speed, and straightforward computations.

使用鹈鹕优化算法为孟加拉国库图布迪亚岛优化孤岛微电网规模

本研究提出了一种基于鹈鹕优化算法（POA）的优化设计方法，根据最佳生命周期成本（LCC）和能源成本（COE），为孟加拉国库图布迪亚的孤岛微电网配置最佳的设计变量大小：光伏组件、风力涡轮机、柴油发电机和电池。此外，还对铅酸、锂离子和镍铁三种独立电池技术进行了经济分析，以找到经济上可行的技术，确保不间断供电。此外，还针对各种可靠性指数和可变利率，对使用 POA 的优化微电网进行了可靠性和敏感性分析。结果表明，建议的 POA 方法提供了使用铅酸电池（PV/WT/LA/DG）的最优岛屿微电网配置，其最低 LCC 为 8334901 美元，COE 为 0.1080 美元/千瓦时，温室气体排放量为 19664 千克/年。此外，还将 POA 生成的结果与遗传算法、粒子群优化、蛾焰优化算法、鲸鱼优化算法和灰狼优化进行了比较。结果发现，与其他优化技术相比，POA 方法具有参数调整能力强、收敛速度快、计算简单等优点，因此能取得更有竞争力的结果。
