Philip Hart is a Lead Electric Power Systems Engineer at GE Research in Niskayuna, NY, where he has been researching event detection and classification techniques for wide area monitoring systems. Prior to joining GE Research in 2018, he received the M.Sc. and Ph.D. degrees in Electrical Engineering as a Morgridge Fellow and research assistant at the University of Wisconsin-Madison. He has co-authored over 15 journal and conference publications and multiple patent applications in the power systems discipline, and in 2017 was the recipient of a Grainger Power Engineering Award. He has served as a reviewer for multiple IEEE Transactions journals and is an active member of local IEEE chapters and conference organizing committees.
Application of a powerful, industry-validated signature identification strategy to a large PMU dataset will be described. The event signatures generated using the semi-supervised strategy are derived from an over-abundance of features calculated in a transparent manner and can be efficiently applied to either historical or streaming PMU data. The signatures can be used to quantify the relative severity, location, and duration of each event, and show promise for integration into tools that provide enhanced power systems reliability, operational efficiency and resiliency. Lessons learned and opportunities for additional research will be discussed.
David Daigle is a Lead Research Engineer with over five years’ experience working at SEL. Mr. Daigle earned his BS in Electrical Engineering from University of Idaho and is currently pursuing his MS in Electrical Engineering from Washington State University. His relevant areas of expertise include transient modeling of power systems, data analytics, and high-performance computing. He has produced a variety of publications for government customers regarding the synthesis of transient power system analysis and machine learning techniques. David currently leading multiple research efforts at SEL that address the confluence of modern data science technologies and electrical power systems.
Schweitzer Engineering Laboratories (SEL), in partnership with Oregon State University (OSU), has developed novel data handling, data anomaly mitigation, and event classification techniques using the FOA 1861 dataset. By using new technologies inspired by SEL’s recent release of the Synchrowave Operations platform, SEL and OSU have applied these techniques with special emphasis on robustness against perturbed or spoofed data and explainability. The result of this joint research effort is an array of techniques that are applicable to every stage of the machine learning pipeline, from preprocessing to event detection. This research contributes directly to the goal of providing situational awareness using real phasor measurement unit data in an online environment such as Synchrowave Operations.
Lei Yang is currently an associate professor in the Department of Computer Science and Engineering at the University of Nevada, Reno. Prior to joining the University of Nevada, Reno, he was an assistant research professor with the School of Electrical Computer and Energy Engineering at Arizona State University. Before that, he was a postdoctoral scholar at Princeton University and Arizona State University. He received the Best Paper Award Runner-up of IEEE INFOCOM 2014. His research interests include big data analytics, AI/ML for cyber-physical systems, edge computing and its applications in IoT and 5G.
In this webinar, Lei Yang will present the FOA 1861 project findings at University of Nevada, Reno. This project aims to develop a robust event diagnostics platform by integrating state-of-the-art tensor analytics and machine learning into real-time grid monitoring. This presentation will outline the tools developed in this project, experimental results using the large PMU datasets, lessons learned and next steps.
