Enhancement Voltage Stability of the Iraqi Power Grid Using Shunt FACTs Devices [PDF]
Engineering and Technology Journal, 2016 Due to raise in demand, the transmission system becomes more exhausted, which in turn, forces the system to be more susceptible to voltage instability. The aim of this research is to study the enhancement in voltage stability margin by installation the ...

Voltage Collapse Stabilization in Star DC Networks
CoRR, 2021 Voltage collapse is a type of blackout-inducing dynamic instability that occurs when power demand exceeds the maximum power that can be transferred through a network. The traditional (preventive) approach to avoid voltage collapse is based on ensuring that the network never reaches its maximum capacity.

Bifurcation, chaos, and voltage collapse in power systems [PDF]
Proceedings of the IEEE, 1995 A model of a power system with load dynamics is studied by investigating qualitative changes in its behavior as the reactive power demand at a load bus is increased. In addition to the saddle node bilification often associated with voltage collapse, the power system exhibits sub- and supercritical Hopf bifurcations, cyclic fold bifurcation, and period ...

Random load fluctuations and collapse probability of a power system operating near codimension 1 saddle-node bifurcation [PDF]
, 2012 For a power system operating in the vicinity of the power transfer limit of its transmission system, effect of stochastic fluctuations of power loads can become critical as a sufficiently strong such fluctuation may activate voltage instability and lead ...

The analysis of voltage collapse induced by nonlinear loads in an arc furnace utilising deep learning-driven TabNet and NODE models [PDF]
PeerJ Computer ScienceElectric arc furnaces (EAF) represent a class of nonlinear loads distinguished by high energy consumption during metal melting processes. Voltage collapses in these systems adversely affect power quality, reduce energy efficiency, and cause significant ...

Voltage Stability Study of the Iraqi Power Grid [PDF]
Engineering and Technology Journal, 2012 It has become an important task for many voltage stability studies to find a voltage stability index. The voltage stability indices provide reliable information about proximity of voltage instability in a power system.

Efficient performance indices for voltage collapse detection [PDF]
2010 IEEE International Energy Conference, 2010 This paper proposes four performance indices (PIs) for efficient detecting the most weakness load buses which may be subjected to voltage collapse occurrence at different operating conditions. The classification of the suggested ranking PIs are dependent on their severity on the voltage collapse.
