CURENT graduate student, Sebastian Martinez Lizana, received the second-place Graduate Presentation Award for his paper titled, “Application of Orthogonal Projectors in Power System Dynamics.” This research applies orthogonal projectors to simplify power system dynamics analysis. By projecting complex, high-dimensional behaviors onto lower-dimensional subspaces, this method enables clear observation of dynamics—such as electromechanical oscillations—at reduced complexity. Validated on a two-machine infinite bus system and the New England 39-bus system, the approach helps uncover specific eigenvalue-driven dynamics, providing deeper insights into stability and control.
The paper was presented at the 56th North American Power Symposium (NAPS 2024) in October on the campus of The University of Texas at El Paso. Sebastian is pictured below with the conference co-chairs, Dr. Paras Mandal (left) and Dr. Yuanni Sang (right). Dr. Hector Pulgar, Associate Professor in the Department of Electrical Engineering & Computer Science at the University of Tennessee, serves as Sebastian’s advisor.
