Data-Driven Dynamic Modeling in Power Systems: A Fresh Look

This article introduces ways to identify dynamic system models using measurement data. In power system analysis, a static model represents the time-invariant input–output relationship of a system, while a dynamic model describes the behavior of the system over time. For example, how will a system transit from one steady-state operation point to another?
