ABSTRACT

The ever-increasing need for fresh water sources puts pressure on researchers to seek new freshwater generation solutions. Amongst them, renewable energy-based applications are attracting increasing interest due to their environmentally friendly nature. In this study, a new approach is proposed that combines renewable energy production system with the reverse osmosis desalination plant. Especially for offshore locations, one of the main problems is to access both energy and fresh water sources. In this study, the wave energy conversion system is used in order to provide a clean energy source for a reverse osmosis desalination-based plant solution. The wave energy converter system is modeled with consideration of a set of irregular sea wave elevation data. The proposed controller of the wave energy converter system adjusts the tuning parameters of the power take-off unit to optimize the operation of the system. The captured power from wave energy conversion system is utilized to produce fresh water from the reverse osmosis-based desalination model. The simulation results indicate that for 20 min time period, the produced water levels in the storage tanks are about 54.8 m³, 97.6 m³, 110.6 m³, and 193.3 m³ for DS1, DS2, DS3, and DS4, respectively. While, one of the main problems to be solved is the mismatch between the produced power by the renewable energy-based system and the required power consumed by the desalination plant. The proposed approach presented in this study indicates that the operation of the two systems in combined manner can be much more feasible solution as it is a very much environmentally friendly and an effective solution.

摘要

对淡水资源不断增长的需求给研究人员带来了寻求新的淡水生成解决方案的压力。其中，基于可再生能源的应用由于其环境友好的性质而吸引了越来越多的兴趣。在这项研究中，提出了一种将可再生能源生产系统与反渗透海水淡化厂相结合的新方法。特别是对于近海地点，主要问题之一是获得能源和淡水资源。在这项研究中，波浪能转换系统用于为基于反渗透海水淡化的工厂解决方案提供清洁能源。波浪能转换器系统是在考虑一组不规则海浪高程数据的情况下建模的。波浪能转换器系统的建议控制器调整动力输出单元的调谐参数以优化系统的运行。从波浪能转换系统捕获的能量用于从基于反渗透的海水淡化模型中生产淡水。模拟结果表明，在 20 min 的时间段内，储罐中的采出水位约为 54.8 m³，97.6米³，110.6米³，和193.3米³为DS1，DS2，DS3，DS4和分别。同时，要解决的主要问题之一是基于可再生能源的系统产生的电力与海水淡化厂消耗的所需电力之间的不匹配。本研究中提出的方法表明，以组合方式运行两个系统可以是更可行的解决方案，因为它是一种非常环保且有效的解决方案。
