Identifiability Limits of Forced Oscillation Sources in Power Systems
Kai Sun
Whether a forced-oscillation source can be uniquely localized depends jointly on the available measurements and the candidate intervention dictionary. This paper considers a single…

Source--Grid Coupling in Power System Oscillations: Observational Equivalence, Feedback Detectability, and Modal Interaction
Kai Sun, Bin Wang
The conventional distinction between forced and natural oscillations treats the oscillation source as external to a fixed power-system boundary. This paper develops a coupling-awar…

A Voronoi Diagram-Based Approach for AC Optimal Power Flow
Mohammed N. Khamees, Kai Sun
The primary goal of Optimal Power Flow (OPF) is to optimize the operation of a power system while meeting the demand and adhering to operational constraints. This paper presents a…
