Presented by: Principal Member Ryan T. Elliott, Ph.D., Sandia National Laboratories, Professor Daniel J. Trudnowsk, Ph.D., Montana State University, Professor Joe H. Chow, Ph.D., Rensselaer Polytechnic Institute

This webinar:
Explores three core themes from Power System Oscillations, Second Edition, an updated text building on Graham Rogers’ seminal work on small-signal stability analysis. First, we reflect on the first edition—its development and lasting influence on oscillation studies. Next, we examine measurement-based modal analysis, showcasing how wide-area measurement systems (WAMS) enable real-time monitoring. Finally, we assess the oscillatory behavior of inverter-based resources (IBRs), such as battery storage and solar PV, and their impact on large-scale power system dynamics. Using examples from the open-source Power and Energy Storage Systems Toolbox (PSTess), we highlight 25 years of progress in the field. Designed for engineers, academics, and researchers, this session bridges Rogers’ foundational contributions with today’s stability challenges, offering practical insights while honoring his legacy.
