Synchrophasors at ComEd

About the Topic

Synchrophasors consist of high-frequency, time-stamped measurements that can be used for wide-area analysis of the transmission system. Synchrophasors are provided by phasor measurement units (PMUs.) The need for increased deployment of PMUs was recognized by the U.S. Department of Energy after the 2003 blackout in the northeast U.S. ComEd participated in a DOE-funded pilot project starting in 2010 that was intended to jump-start PMU deployment. In 2015, ComEd initiated an effort to increase its deployment from the existing 12 PMUs to a large-scale deployment providing visibility for most, if not all, of its transmission system. Part of the project involved new IT systems to support 500-1000 PMUs, along with applications for real-time and engineering analysis. ComEd currently has over 70 PMUs located at more than 30 substations and plans to more than double the number of deployed PMUs within the next two or three years.

This presentation will describe the infrastructure needed to support a large number of PMUs and the processes put in place to enable PMUs to be easily deployed while maintaining upgradability to future requirements around cyber security. The presentation will also highlight several of the phenomena occurring on the transmission system that would not be recognizable without PMUs. Possible future use cases at ComEd will also be discussed.

About the Speaker

David C. Schooley is a Principal Engineer in the Transmission Strategy department at Exelon Utilities. His Bachelor of Science and Master of Science degrees in Electrical Engineering are from Oklahoma State University, and his Ph.D. degree in Electrical Engineering is from the Georgia Institute of Technology where he studied the integration of large amounts of wind and solar energy into the generation mix. In a previous life, he was employed as an electrical engineer at Southern Research Technologies in Birmingham, Alabama, where he designed digital hardware and wrote software for guided missiles and airborne data-acquisition platforms.

His job responsibilities at ComEd, now Exelon Utilities, have included work in transmission operations, where he was involved in demand side management, load forecasting, and the implementation of real-time visualization of the transmission system in ComEd's control room. He currently works in ComEd's Transmission Planning department where he is primarily involved with dynamic modeling and simulation of the transmission system. David is the Exelon lead for PMU deployment and applications.
