TLDR
It is shown that power systems are completely controllable within a region of the state space within the complete controllability region, implying that during emergencies, the movement of the power system states can be directed toward a desired operating point so that events like a voltage collapse can be avoided.Abstract:
This paper summarizes our results of a study on the complete controllability of power systems. With a nonlinear dynamic power system model, it is shown that power systems are completely controllable within a region of the state space. In other words, with the available controls, a power system can be steered from one state to any other state within the complete controllability region. The study also provides a strategy for constructing the complete controllability region. The results imply that during emergencies, if the power system states are in the complete controllability region, the movement of the power system states can be directed toward a desired operating point so that events like a voltage collapse can be avoided.read more

Shrinking stability regions and voltage collapse in power systems
TL;DR: In this article, the dynamic process of voltage collapse is analyzed based on three mechanisms: on-load tap-changing, load dynamics, and generator excitation limiting, and the interaction among these mechanisms and how the voltage collapse takes place are thoroughly investigated in a general interconnected network model under the assumption that system frequency remains unchanged.
