Abstract Desalination is a method used to produce water for human consumption and/or industrial use. Seawater treatment systems powered by renewable sources are regarded as sustainable methods for providing drinking water for coastal zones and islands where there is no electrical grid. This study evaluated the operations of seven different (off-grid) power systems (wind-photovoltaic-diesel-battery) used to satisfy the electrical energy demand of a small-scale reverse osmosis system with a capacity of 1 m3/h used on Bozcaada Island, Turkey. The hybrid optimisation model for electric renewable (HOMER) software was selected to perform techno-economic analyses of the systems. On the other hand, the reverse osmosis system analysis model (ROSA) was used to determine the energy requirement of the reverse osmosis system examined in this study. The results of this study showed that the electricity cost was $0.308/kWh for the optimal system consisting of wind turbines with a rated power of 10 kW, a 20 kW PV panel, and a diesel generator with a rated power of 8.90 kW, while the water cost was $2.20/m3. Additionally, the results showed that combining the hybrid power system and reverse osmosis system could be a cost-effective method for remote areas with good wind and solar power potential.

混合动力（风-光伏-柴油-电池）和海水反渗透系统的集成，用于小规模海水淡化应用

摘要 海水淡化是一种用于生产人类消费和/或工业用水的方法。由可再生能源供电的海水处理系统被认为是为没有电网的沿海地区和岛屿提供饮用水的可持续方法。本研究评估了用于满足 Bozcaada 上使用的容量为 1 立方米/小时的小型反渗透系统的电能需求的七种不同（离网）电力系统（风-光伏-柴油-电池）的运行情况岛，土耳其。选择可再生电力（HOMER）软件的混合优化模型来执行系统的技术经济分析。另一方面，反渗透系统分析模型 (ROSA) 用于确定本研究中检查的反渗透系统的能量需求。本研究结果表明，由额定功率为 10 kW 的风力涡轮机、一个 20 kW 的光伏电池板和一台额定功率为 8.90 kW 的柴油发电机组成的最佳系统的电费为 0.308 美元/kWh，而水费为 $2.20/m3。此外，结果表明，对于风能和太阳能潜力良好的偏远地区，将混合动力系统和反渗透系统相结合可能是一种具有成本效益的方法。
