AI中文摘要：
本文开发了一个分析框架，用于在结合热法和反渗透（RO）脱盐的可再生能源海水淡化厂（WDP）中，实现水、电和绿氢的利润最大化调度。最优调度揭示了脱盐装置、电解槽和电网互动的调度方案都可以表示为可再生能源发电量的闭式函数。在可再生能源出力较低时，该厂依赖热法脱盐和电网电力，同时将反渗透脱盐和氢气生产维持在最低设定点。在出力较高时，该厂减少热法脱盐，增加反渗透脱盐，并将剩余电力和水分配给氢气生产。对于预先计算的中间范围内的可再生能源出力，WDP在内部平衡能源，根据氢气和反渗透水的相对边际价值分配资源。使用真实太阳能和工厂数据的仿真表明，将反渗透和热法脱盐与可再生能源发电和氢气生产相结合，可实现最高日利润75.945 k$，比不含氢气的最佳配置高出15.1%。
英文摘要：
This paper develops an analytical framework for profit-maximizing dispatch of water, electricity, and green hydrogen in a renewable-powered water desalination plant (WDP) combining thermal and reverse osmosis (RO) desalination. The optimal dispatch reveals that the schedules of the desalination units, electrolyzer, and grid interaction can all be characterized in closed form as functions of renewable generation. At low renewable output, the plant relies on thermal desalination and grid power while maintaining RO desalination and hydrogen production at their minimum setpoints. At high output, it reduces thermal desalination, increases RO desalination, and allocates surplus power and water to hydrogen production. For renewable output within a precomputed intermediate range, the WDP balances energy internally, allocating resources based on the relative marginal values of hydrogen and RO water. Simulations using real solar and plant data show that integrating RO and thermal desalination with renewable generation and hydrogen production achieves the highest daily profit of 75.945 k$, exceeding the best configuration without hydrogen by 15.1%.
