在认识到实现碳减排和减轻可再生能源的可变性的显着优势，越来越多的联合循环（CC）单位的安装已被观察到最近。发电组合的这一新转变促使独立系统运营商（ISO）在其机组组合（UC）工具中不断增强CC机组模型，以便通过准确捕获其运行特征来获得物理上可行且运行可靠的CC机组机组组合和发电调度计划。为此，本文准确地模拟了在配置转换过程中的CC单元的单个涡轮的启动和关闭过程。为进一步提高建模精度，还提出了一种动态斜升模型和相应的单个水轮机旋转备用模型。采用一个改进的IEEE 118节点系统与多个CC单元评估所提出的模型。
In recognizing significant advantages in achieving carbon emission reduction and mitigating variability of renewables, an increasing installation of combined-cycle (CC) units has been observed recently. This new shift in the generation portfolio has urged Independent System Operators (ISO) to continuously enhance CC unit models in their unit commitment (UC) tools, in order to derive physically feasible and operationally reliable unit commitment and generation dispatch schedules of CC units by accurately capturing their operation features. To this end, this paper accurately simulates startup and shutdown processes of individual turbines of a CC unit during the configuration transition procedure. A dynamic ramping model and the corresponding spinning reserve model for individual turbines are also proposed to further enhance the modeling accuracy. A modified IEEE 118-bus system with multiple CC units is adopted to evaluate the proposed models.
