Increasing Transparency of Transmission Constraints on the Electricity Trading Market

本项目由“研究中心-小企业协同研发”倡议支持。这项研究涉及电力系统工程研究中心（PSerc）和增量系统公司（Incremental Systems Corp.）之间的联合研究，前者是IUCRC总部设在康奈尔大学，华盛顿州立大学（WSU）是其合作伙伴。增量系统公司是一家位于华盛顿州Issaquah的小公司。目标是开发并向工业界转让能够将详细的实时数据转换为电力交易商所需的简单潮流数据的技术。这些方法将允许近乎实时地查看必要的数据，以确定交易是否在操作限制范围内。WSU将制定一个足够健壮的数据模型，允许从公共信息模型（CIM）映射到负载流模型，并将基于最先进的方法开发适当的状态估计方法，用于不良测量检测、拓扑确定和参数估计。此外，WSU将设计并实现数据库软件，该软件可以将CIM的实时数据（状态估计器的输出）投影到标准负载流数据模型（如PTI）上。增量系统将提供工业专业知识，建议和对方法的批评，以及对方法的设计和应用提供支持。当WSU将编写软件时，Incremental Systems的数据库软件知识将被整合到软件实现中，并且他们在几个小时内的大部分工作预计将属于这项任务。此外，增量系统将通过使用操作员培训模拟器对实际系统进行模拟测试软件，重点是演练数据故障、总线分裂、设备中断和其他数据困难。WSU将进行案例研究，根据增量系统的标准评估性能，并对软件进行必要的更改。

EEC-9903824TomsovicThis project is supported under the initiative on "Research Centers - Small Firms Collaborative R&D." The study concerns joint research between the Power Systems Engineering Research Center (PSerc), an IUCRC headquartered at Cornell University that includes Washington State University (WSU) as a partner, and Incremental Systems Corp., a small firm located in Issaquah, WA. The objective is to develop and transfer to industry the techniques that can translate the detailed real-time data to the simple power flow data required by the electricity traders. The methods will allow for viewing in near real-time the data necessary to determine if trades fall within operational limits. WSU will formulate a data model that is sufficiently robust to allow mapping from the Common Infromation Model (CIM) to the load flow model, and will develop appropriate state estimation approaches based on the state-of-the-art methods for bad measurement detection, topology determination and parameter estimation. In addition, WSU will design and implement database software that can project the real time data (output of the state estimator) from the CIM onto a standard load flow data model, such as, PTI. Incremental Systems will provide industrial expertise, advise and critique on the methodology as well as provide support on the design and application of the the methods. While WSU will write the software, Incremental Systems' knowledge of the database software will be integral to the software implementation and most of their effort in hours is expected to fall under this task. Furthermore, Incremental systems will test software through simulation using the the Operator Training Simulator for a practical system with an emphasis on exercising data failures, bus splits, equipment outages and other data difficulties. WSU will run the cases studies, evaluate the performance based on criteria from Incremental Systems and make any necessary changes to the software.
