While it is widely recognized that weather impacts electric grid operations and planning, historically weather information has only been implicitly included in common grid analysis packages. Building on a presentation from last year, this presentation provides new developments in the application of weather information in the power flow and the optimal power flow (OPF). Key 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. One new development considered is the now 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. The presentation shows how this information, along with present and forecasted results, can be directly utilized in the power flow and OPF including time-series analysis. The approach is demonstrated on several different electric grids ranging in size up to 120,000 buses.
The webinar was held on Zoom at 3 p.m. CST on January 24, 2024.

Speaker
Dr. Thomas J. 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 the Director of TEES Smart Grid Center, working in the area of large-scale electric power systems. Prior to joining TAMU in 2017, he 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 the original developer of PowerWorld Simulator, a co-founder of PowerWorld Corporation, an author of a widely used Power System Analysis and Design book and is a member of the US National Academy of Engineering.
