Description
Geomagnetic disturbances (GMDs), caused by solar coronal mass ejections, have the potential to significantly impact the operation of the high voltage electric grid by causing geomagnetically induced currents (GICs). Over the last decade there has been significant research, industry interest, and regulatory concern about the impact of GMDs on the high voltage electric grid. The purpose of this two-day short course is to put the GMD issue into proper perspective by providing a comprehensive coverage of what is currently known about the impact of GMDs on the grid, the tools being used for their assessment in planning and operations, and the current areas of research.
The course philosophy is to provide in-depth coverage of the topics, but to do so using a practical, hands-on approach. For example, the course provides a detailed consideration of what is needed to do the GMD assessments required for NERC TPL-007-4, and also contains an interactive, real-time simulation of the operational impacts of GMDs on the grid. Throughout the course concepts will be illustrated using common industrial tools including those from EPRI and PowerWorld Simulator. Collectively the three course instructors have wide experience in this area doing electric power system studies, software tool development, research and engineering education (Hours: CEU 1.4, PDH 14).
Who Should Attend
The course is designed to provide a comprehensive coverage of the impacts of GMDs on high voltage electric grids. It is ideally suited for electrical engineers who work in the areas associated with either electric grid planning or operations, and for new graduates who would like to rapidly gain experience in the area of GMD grid impacts. The course will also be useful for technical staff in regulatory agencies, for technical managers, for academics wishing to gain practical knowledge in this important area, and for graduate students interested in careers in the power industry.
This course counts toward the Texas A&M Certificate in Electrical Power Engineering.

Instructors
Bob Arritt is a Technical Executive at the Electric Power Research Institute (EPRI). He received a BS, magnum cum laude, in electrical engineering from West Virginia Institute of Technology in
Montgomery, West Virginia. He received a MS degree in electrical engineering from Worcester Polytechnic Institute in Worcester, Massachusetts. His current research activities include leading the
geomagnetic disturbance work, distributed resources, system transients, harmonics and protection. Mr. Arritt joined EPRI in 2007. Prior to joining EPRI, Mr. Arritt worked for Raytheon in Sudbury, MA where
he worked in the Power and Electronic Systems Department. At Raytheon he was awarded the 2006 Raytheon Technical Honors Award for Peer and Leadership Recognition for Outstanding Individual Technical Contribution and also received a 2005 Raytheon Author’s Award for design of a Phase-Shifted Transformer for Harmonic Reduction. Since at EPRI, Bob has been awarded the Chauncey Award for his outstanding innovative and achievements in science and technology. Mr. Arritt holds a US Patent as the lead inventor for “Method for Detecting an Open-Phase Condition of a Transformer,” has authored several technical paper, is an IEEE Senior member, and Professional Engineer licensed in the State of Tennessee.
Tom Overbye is a Professor and holder of the O’Donnell Foundation Chair III in the Department of Electrical and Computer Engineering at Texas A&M University (TAMU), and Director of Smart Grid Center at the Texas Engineering Experiment Station (TEES). He received his BS, MS, and Ph.D. degrees in Electrical Engineering from the University of Wisconsin-Madison. Before starting his academic career he was employed with Madison Gas and Electric Company, working in their planning and operations departments. He is the original developer of PowerWorld Simulator (a widely used power system planning tool), a co-founder of PowerWorld Corporation, and an author of a widely used Power System Analysis and Design book. He is a recipient of the IEEE Power and Energy Society Outstanding Power Engineering Educator Award, an EEE Fellow, and a member of the US National Academy of Engineering. Tom is a leading researcher in the electric grid impacts of geomagnetic disturbances (GMDs) and was also responsible for the integration of GMD analysis into PowerWorld Simulator.
Jonathan Snodgrass is a Senior Research Engineer in the TAMU Department of Electrical and Computer Engineering, and Assistant Director for Modeling, Simulation and Outreach at TEES Smart Grid Center at the Texas Engineering Experiment Station (TEES), working under Professor Tom Overbye in the area of large-scale electric power systems. He received his BS and MS degrees at Texas A&M University, and MS and PhD degrees at the University of Wisconsin-Madison, all in electrical engineering. His primary research area is in power system network planning and resilience, with current projects focusing on light, medium and heavy-duty EV integration using combined transmission and distribution co-simulation. His other research areas include modeling impact of high-impact, low-frequency events (such as GMD and EMP) on the electric grids, power system optimization, and microgrids. He also worked for two years at Zachry Engineering Corporation in Amarillo, TX, designing simple and combined cycle natural gas generating plants.
