Enhancement Voltage Stability of the Iraqi Power Grid Using Shunt FACTs Devices [PDF]

open access: yesEngineering 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

open access: yesCoRR, 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.

Voltage Stability Study of the Iraqi Power Grid [PDF]

open access: yesEngineering 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.

Investigating Various Severity Factor Behaviors for Operational Risk Assessment

open access: yesElectricity, 2022
Operational risk assessment is a stochastic approach to quantify the operational security of power systems. In this study, the interrelation between severity factor and operational risk, two important parameters in operational risk assessment, is ...

Bifurcation, chaos, and voltage collapse in power systems [PDF]

open access: yesProceedings 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 ...

New Line Voltage Stability Index (BVSI) for Voltage Stability Assessment in Power System: The Comparative Studies

open access: yesIEEE Access, 2022
Modern power utilization has been forced to operate close to their stability limits, which may lead to voltage instability or collapse owing to the stressed operating conditions of networks.

Efficient performance indices for voltage collapse detection [PDF]

open access: yes2010 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.

The analysis of voltage collapse induced by nonlinear loads in an arc furnace utilising deep learning-driven TabNet and NODE models [PDF]

open access: yesPeerJ Computer Science
Electric 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 ...
