为了确保可靠且连续的电能供应，运营商必须管理数百个具有复杂运行需求的发电机，维持同步性并管理数千个传输资产。由于严格的可靠性标准，资源不确定性和有限的经济能源存储，出现了进一步的并发症。随着算法性能和硬件的进步，此类优化问题仍然需要经过设计的简化市场结构。因此，市场运营商必须调整提出的市场解决方案，以获得有效的解决方案。介绍了与此类市场调整有关的现有行业实践的概述，称为截止市场校正。本文还分析了市场的含义，并需要针对日期安排过程的市场范围校正。创建了多种市场外校正算法，并用于分析对市场解决方案和定居点的潜在影响。最后，将这些解决方案与广泛形式的随机单位承诺解决方案进行了比较。
In order to ensure a reliable and continuous supply of electric energy, operators must manage hundreds to thousands of generators with complex operating requirements, maintain synchronism, and manage thousands of transmission assets. Further complications arise due to stringent reliability standards, resource uncertainty, and limited economical energy storage. With advances in algorithmic performance and hardware, such optimization problems still require an engineered and simplified market structure. Market operators must therefore adjust the proposed market solution in order to obtain a valid solution. An overview of existing industry practices related to such market adjustments, referred to as out-of-market corrections, is presented. This paper also analyzes the market implications and required out-of-market corrections for the day-ahead scheduling process. Multiple out-of-market correction algorithms are created and used to analyze the potential impacts on market solutions and settlements. Finally, such solutions are compared against an extensive form stochastic unit commitment solution.
