This presentation covers some of the more recent developments in the modeling of weather and other environmental inputs (ENIs) such as earthquakes and wildfires in the power flow and other related tools, with a focus on electric grid transmission planning. The presentation is motivated because of the rapidly growing dependence of electric grids on the weather, and the need to consider the impact of more severe resiliency events. A key focus is to show that environmental inputs can be directly integrated into existing power flow and related tools such as contingency analysis and optimal power flow. Issues addressed include the availability of weather information sufficient for power flow analysis, the mapping of weather information to electric grid components, a flexible and extensible modeling approach for relating weather values to the power flow models, and the visualization of the weather impacts on the results. Among the new developments considered are 1) the use of the US National Oceanic and Atmospheric Administration (NOAA) High-Resolution Rapid Refresh (HRRR) weather data, which provides 3-km resolution, 2) the convenient integration of ERA5 results, which provides fifth generation reanalysis weather data covering the global on a 0.25 degree grid going back January 1940, 3) the ability to determine outlier weather scenarios, 4) the application of other environmental inputs such as earthquakes and smoke, 5) consideration of electric grid modeling of ENIs and their electric grid impacts.

Speaker:
Thomas J. Overbye, 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 the director of the Texas A&M Engineering Experiment Station (TEES) Smart Grid Center
Prior to joining TAMU, Dr. Overbye was a Professor at the University of Illinois at Urbana-Champaign. 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. He is also the original developer of PowerWorld Simulator, co-founder of PowerWorld Corporation, an author of a widely used Power System Analysis and Design book, and a member of the US National Academy of Engineering.
