这封信调查了加州独立系统运营商（ISO）和Midcontinent ISO在基于绩效的监管市场中计算绩效准确度分数的方式之间的根本差异。这两个ISO倾向于遵循联邦能源管理委员会第755号命令，根据其实际性能支付监管资源-无论是传统发电机还是分布式和需求侧资源。系统地说明了每种方法的优缺点。首先，真实世界的ISO数据被用来表明，这两种方法在类似的监管性能场景下的评分准确性可能存在重大差异。接下来，对观察到的差异的根本原因进行数学研究。最后，提出了一些建议，以改善这些评分方法，如果这些或其他ISO寻求完善他们的评分公式。
This letter investigates the fundamental differences between how California Independent System Operator (ISO) and Midcontinent ISO calculate performance accuracy scores in their performance-based regulation markets. Both ISOs tend to follow the Federal Energy Regulatory Commission order 755 to pay regulation resources—whether conventional generators or distributed and demand side resources—based on their actual performance. The advantages and disadvantages of each method are systematically explained. First, real-world ISO data are used to show that there may exist major differences between these two methods in scoring accuracy under similar regulation performance scenarios. Next, the root causes for the observed differences are studied mathematically. Finally, some suggestions are made to improve these scoring methods; should these or other ISOs seek to refine their scoring formulas.
