This paper investigates the potential and feasibility of an integrating hybrid renewable power generation system with a large-scale reverse osmosis desalination plant to provide electricity, heat, and water for the New Capital International Airport, Egypt. The proposed energy system contains photovoltaic panels, wind turbine, combined heat-power microturbine generator, diesel generator, batteries, converter, thermal load controller, and a boiler. A comprehensive energy-economic-environmental optimization analysis was performed to optimize energy systems in which 16-feasible solutions were evaluated and compared. The results revealed that the optimal system has the least net present and energy costs by 1.54 M$ and 0.089 $/kWh, respectively, and needs only 1.12 years to recover the invested money. Moreover, the proposed system produces emissions of 59.5% less than the base-case. The optimal system has a negligible unmet load ratio since it has a negligible loss of power supply possibility of 0.0993%. The thermal load controller has a significant impact on reducing the net present cost, cost of energy, emissions, and needed batteries by 52%, 56.4%, 36.5%, and 90%, respectively compared to the base-case. The obtained results are expected to attract large investments in clean energy and water desalination because of the government's challenges in such fields.

本文研究了将混合可再生能源发电系统与大型反渗透海水淡化厂整合在一起，为埃及新首都国际机场提供电，热和水的潜力和可行性。拟议的能源系统包括光伏板，风力发电机，热电联合微型发电机，柴油发电机，电池，转换器，热负荷控制器和锅炉。进行了全面的能源-经济-环境优化分析，以优化其中评估并比较了16种可行解决方案的能源系统。结果表明，最优系统的净现值和能源成本分别最低，分别为1.54 M $和0.089 $ / kWh，并且仅需要1.12年即可收回投资。此外，拟议的系统产生的排放量比基本情况少59.5％。最佳系统的未满足负载比可忽略不计，因为它的电源可能性损失可忽略不计为0.0993％。与基本情况相比，热负荷控制器对降低当前的净成本，能源成本，排放成本和所需的电池分别有52％，56.4％，36.5％和90％的影响。由于政府在这些领域的挑战，预期获得的结果将吸引大量投资于清洁能源和海水淡化。与基本情况相比，分别为56.4％，36.5％和90％。由于政府在这些领域的挑战，预期获得的结果将吸引大量投资于清洁能源和海水淡化。与基本情况相比，分别为56.4％，36.5％和90％。由于政府在这些领域的挑战，预期获得的结果将吸引对清洁能源和海水淡化的大量投资。
