Abstract In this paper, a new short-term daily scheduling model is proposed and formulated. In the proposed model, thermal power plant will be optimally scheduled in a system with water desalination units. For the thermal units, various cost terms including start-up, shut-down, and also fuel cost are considered and modeled. Also, thermal dynamics of the plants including power generation ramp-up and ramp-down, minimum up and down time limits, and start-up and shut-down ramps are considered. In addition, energy storage batteries as well as water storage tanks of the desalination units are modeled. The proposed model is a mixed integer linear programming (MILP) for simultaneous scheduling of thermal power plants and desalination units while considering transmission constraints. Power and water balance at the network buses in addition to the power flow constraints of the lines are considered. Various membrane and thermal desalination methods are modeled. The proposed model is implemented on a test case and the simulation results show a significant reduction in the system operating costs as well as improved performance of both the thermal power plants and the desalination unit. The proposed scheduling method can be used for the various future studies of joint power-water production and coordination.

考虑蓄能蓄水的火力机组承诺海水淡化机组建模与集成

摘要 本文提出并制定了一种新的短期每日调度模型。在提议的模型中，火力发电厂将在带有海水淡化装置的系统中进行最佳调度。对于热力机组，考虑并建模了各种成本项，包括启动、关闭和燃料成本。此外，还考虑了电厂的热动态，包括发电量上升和下降、最小上升和下降时间限制以及启动和关闭斜坡。此外，还对海水淡化装置的储能电池和储水罐进行了建模。所提出的模型是一种混合整数线性规划 (MILP)，用于在考虑传输约束的情况下同时调度火力发电厂和海水淡化装置。除了线路的潮流限制外，还考虑了网络总线的电力和水平衡。模拟了各种膜和热脱盐方法。所提出的模型在一个测试案例中实施，仿真结果表明，系统运行成本显着降低，热电厂和海水淡化装置的性能也有所提高。所提出的调度方法可用于联合电力-水生产和协调的各种未来研究。所提出的模型在一个测试案例中实施，仿真结果表明，系统运行成本显着降低，热电厂和海水淡化装置的性能也有所提高。所提出的调度方法可用于联合电力-水生产和协调的各种未来研究。所提出的模型在一个测试案例中实施，仿真结果表明，系统运行成本显着降低，热电厂和海水淡化装置的性能也有所提高。所提出的调度方法可用于联合电力-水生产和协调的各种未来研究。
