Inertia, Stability, and Nonlinear Dynamics in a Grid with Inverter-Based Resources
The dynamic behavior of the electric grid is changing rapidly as inverter-based resources (IBRs) replace traditional synchronous generators in delivering critical system services. This rapid shift—driven by the growth of distributed generation and energy storage—requires a fundamental re-evaluation of how we define and assess grid stability. In particular, the traditional concept of grid “inertia” must be reconsidered to ensure that stability metrics accurately reflect modern system behavior.
In this presentation, I will discuss the nonlinear dynamic nature of the power grid, the influence of increasing IBR penetration on stability, and our recent work on transient stability assessment. I will highlight examples involving grid-forming inverter models and our efforts to incorporate improved stability metrics into simulation frameworks. By combining physical intuition with practical modeling, this ongoing work aims to inform new approaches to stability assessment for the future power grid.

John Zhang
Biography:
Ziang “John” Zhang is an Associate Professor in the Department of Electrical and Computer Engineering at Binghamton University, State University of New York. He earned his Ph.D. in Electrical Engineering from North Carolina State University in 2013. From 2013 to 2014, he worked as a postdoctoral researcher at the ABB U.S. Corporate Research Center in Raleigh, North Carolina.
Dr. Zhang leads a research team focused on power system transient stability and the integration of battery energy storage systems. He is the principal investigator for multi-institution research projects funded by the National Science Foundation, the U.S. Department of Energy, and the State of New York. He serves on the organizing committees of major IEEE Power & Energy Society conferences and contributes to IEEE standards development.
