Increasing Transparency of Transmission Constraints on the Electricity Trading Market

EEC-9903824Tomsov本项目由“研究中心--小企业协作研发”项目支持。这项研究涉及电力系统工程研究中心(PSerc)和增量系统公司(一家位于华盛顿州Issaquah的小公司)的联合研究。电力系统工程研究中心是总部设在康奈尔大学的IUCRC，合作伙伴包括华盛顿州立大学(WSU)。其目标是开发并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转移到工业中。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，以允许从公共信息模型(CIM)到潮流模型的映射，并将基于最新的不良测量检测、拓扑确定和参数估计方法开发适当的状态估计方法。此外，WSU将设计和实施数据库软件，该软件可以将实时数据(状态估计器的输出)从CIM投影到标准潮流数据模型，如PTI。增量系统将提供行业专业知识，就方法提供建议和批评，并就方法的设计和应用提供支持。虽然WSU将编写软件，但增量系统公司对数据库软件的知识将是软件实施不可或缺的一部分，预计他们在几个小时内的大部分工作将属于这项任务。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来测试软件，重点是执行数据故障、总线拆分、设备停机和其他数据困难。华盛顿州立大学将运行案例研究，根据增量系统的标准评估性能，并对软件进行任何必要的更改。

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.
