Abstract
For future power grids with intermittent renewable sources and responsive loads, it is essential to establish a dynamic operation paradigm in contrast to today's operation built on static state estimation. Recent developments in phasor technology make estimating dynamic states possible with high-speed time-synchronized measurement data. Advancements in high performance computing enable the associated computation to be finished within the short time intervals required for real-time power grid operation. This paper proposes such a dynamic paradigm with three fundamental components: dynamic state estimation, look-ahead dynamic simulation, and dynamic contingency analysis. Essentially, these three functions provide a complete picture of the current, future and potential dynamic states of a power grid. From these three components, other applications can then be developed for operation and control.
