TLDR
In this paper, the steady-state voltage stability of a power system was studied via linearized dynamical equations of on-load tap changers and steady state decoupled reactive power flow equations.Abstract:
The steady-state voltage stability of a power system is studied via linearized dynamical equations of on-load tap changers and steady-state decoupled reactive power flow equations. A set of conditions is derived for a hyperbox of tap settings and load bus voltages to satisfy the steady-state stability requirements. The results can be used to construct steady-state voltage stability regions for the security monitoring of power systems.read more

Calculation of the extreme loading condition of a power system for the assessment of voltage stability
TL;DR: The extreme loading condition (XLC) of a power system is defined by assuming a load increase (according to a predefined pattern for both active and reactive powers) until a maximum is reached for one of the loads as discussed by the authors.

On the evaluation of voltage collapse criteria
J.-C. Chow,Robert Fischl,H. Yan +2 more
TL;DR: In this article, the authors provide an approach that enables a power system operator or planner to evaluate his or her alternatives in selecting a certain voltage collapse criterion, which must guarantee that the risk of making a wrong decision is minimal for any operating point and disturbance.

A framework to predict voltage collapse in power systems
TL;DR: In this paper, a framework based on region-wise partitioning is presented which accounts for several of the mechanisms to predict voltage collapse and can serve as a basis for comparing the effectiveness of performance indices to predict on-line, voltage collapse problems in power systems.
