论文摘要
在过去的十年中，美国太平洋西北系统的建模挑战已经发展。除了经典的建模困难（例如具有许多操作限制的复杂水力级联）外，我们已经看到了系统内部和外部可变可再生能源的渗透率更高，导致内部问题以及与西海岸系统完全不同的功率交流。该系统的充分性和可靠性的分析促使了五步模拟器的设计和实施，包括四个计划阶段和操作步骤。这五个级别被建模为数学程序，这些程序通过固定决策和预测的改进从上到下链接，另一方面，它们也通过系统更新状态从底部到顶部链接。通过在大规模平行的环境中应用最终的优化技术和高性能数据库，使数百万个数学程序的解决方案成为可能。
Modelling challenges of the United States Pacific Northwest system have grown in the last decade. Besides classical modelling difficulties such as a complex hydro cascade with many operational constraints, we have seen higher penetration of variable renewable energy inside and outside the system leading to internal issues and completely different power exchanges with the West Coast System. The analysis of adequacy and reliability of this system motivated the design and implementation of a five-step simulator including four planning phases and an operation step. The five levels were modeled as mathematical programs that are linked from top to bottom by fixed decisions and improvements in forecasts, on the other hand they are also linked from bottom to top by system updated states. The solution of the millions of resulting mathematical programs was made possible by applying state of the art optimization techniques and high performance data bases in a massively parallel environment.
