Abstract Reverse osmosis desalination plants running with renewable energy-based microgrids are gaining importance. A new approach for the design of microgrid with a reverse osmosis desalination plant system called coordinated sizing is proposed in this manuscript. The proposed algorithm is a leader-follower structured optimization process. The desalination plant is segregated as units and each unit can be operated independently as required. A direct load control-demand side management is incorporated into the sizing process to determine the optimal flexible operation of the desalination plant and microgrid's power dispatch simultaneously. A conceptual microgrid powering desalination plant is considered to evaluate performance of the proposed coordinated sizing method. Different evolutionary algorithms are applied for solving the sizing problem and the results are analyzed. The proposed coordinated sizing method is compared with the conventional sizing method. With and without the flexible operation of desalination plant cases are considered to compare economy of the plant. The results demonstrate that the proposed coordinated sizing is cost-effective and provide better operational flexibility.

具有需求侧管理的能源和反渗透海水淡化厂的优化设计，以实现具有成本效益的淡水生产

摘要 使用基于可再生能源的微电网运行的反渗透海水淡化厂正变得越来越重要。本手稿提出了一种设计具有称为协调大小的反渗透海水淡化厂系统的微电网的新方法。所提出的算法是一个领导者跟随者结构化的优化过程。海水淡化厂为单元隔离，每个单元可根据需要独立运行。直接负荷控制-需求侧管理被纳入规模调整过程，以同时确定海水淡化厂和微电网电力调度的最佳灵活运行。考虑为海水淡化厂供电的概念性微电网来评估所提出的协调选型方法的性能。应用不同的进化算法来解决尺寸问题，并对结果进行分析。所提出的协调上浆方法与传统上浆方法进行了比较。有和没有海水淡化厂灵活运行的情况被认为是比较工厂的经济性。结果表明，建议的协调大小调整具有成本效益，并提供更好的操作灵活性。
