SGER: The Engineering Econometrics of Market Power in Electric Power Systems

在许多重组后的电力市场中，高平均价格和高波动性引发了人们对发电企业滥用市场力量的担忧。与此同时，发电机不再披露有关发电真实成本的信息，这些信息在监管下很容易获得。因此，使用实际价格与竞争价格的比较作为确定市场力量的潜力或使用的基础是不切实际的。这项建议是关于开发一种新的指数或指标，能够评估发电商的市场力量潜力，而不是依赖于无法获得的信息或数据。与经济学家使用的其他指数不同，新指数包含了关于互联网络、其当前拓扑结构、约束和限制的工程信息。如果该指数像它看起来那样具有创新性，它也应该与识别国家利益的传输瓶颈有关，并能够帮助确定缓解这些瓶颈的方法。随着电力业务从监管向市场的重组，监测和评估业绩的方法至关重要。新的FERC NOPR关于标准市场设计的建议呼吁对市场监测以及市场缓解程序提出想法。实际上，文献中的所有指标都忽略了市场运作对工程的影响，无论是规划还是运营。本文提出的新指标在概念上是创新的，如果工作成功，它将为电力行业提供一种新的绩效评估方法，从而对未来电力系统的监管产生重大影响。然而，这项工作风险很高，因为尽管该指数看起来很有吸引力，但实时计算它所需的计算工具和数据可能会施加无法容忍的限制。目前，工程信息不是电力市场评估的一部分，充其量只是一个主要的疏忽。成功地将这些信息纳入基于敏感性的衡量标准将产生更广泛的影响，增强经济学家和工程师对这类信息重要性的理解。这项工作的成果将在各种跨学科会议上公布。这些信息还将被整合到ECE551/AEM655电力系统工程与经济学课程中，这是一门由工程师PI和经济学家Timothy Mont教授共同教授的课程。

The high average prices and high volatility of prices in many restructured markets for electricity have raised concerns about the abuse of market power by generators. At the same time, information about the true costs of generation, that was readily available under regulation, is no longer disclosed by generators. Hence, it is becoming impractical to use a comparison of actual prices with competitive prices as the basis for identifying either the potential for or the use of market power. This proposal is about developing a new index or metric capable of evaluating a generator's potential for market power that doesn't rely on unavailable information or data. Unlike other indices in use by economists, the new index carries with it engineering information about the interconnecting network, its current topology, constraints and limitations. If the index is as innovative as it appears to be, it should also be relevant to identifying transmission bottlenecks of National interest and be able to assist in identifying ways to relieve them.With the restructuring of the electric power business from regulation to markets, ways to monitor and evaluate the performance are essential. The new FERC NOPR on Standard Market Design calls for ideas on market monitoring as well as market mitigation procedures. Virtually all of the metrics in the literature ignore the effects of market operation on the engineering, both planning and operations. The new metric suggested here is innovative in concept and, if the work is successful, it will provide the electric power industry with a new way to evaluate performance and thus, will have a substantial impact on the oversight of future electric power systems. Yet, the work is high risk because, while the index looks attractive, the computational tools and the data needed to compute it in real time are may impose intolerable limits. At present engineering information is not a part of electric power market evaluations, a major oversight at best. Successfully incorporating this information into a sensitivity-based measure will have thebroader impact of enhancing the understanding of the importance of this type of information by economists and engineers alike. The results of this work will be presented at various interdisciplinary conferences. The information will also be integrated into the course ECE551/AEM655 Power Systems Engineering and Economics, a course co-taught by the PI, an engineer, and Professor Timothy Mount, an economist.
