Direct Detection of Voltage Collapse in Electrical Power System
Tikrit Journal of Engineering Sciences, 2011 Voltage stability is indeed a dynamic problem. Dynamic analysis is important for better understanding of voltage instability process. In this work an analysis for voltage stability from bifurcation and voltage collapse point of view based on a center ...

Voltage collapse in power systems [PDF]
IEEE Circuits and Devices Magazine, 1992 The stages of a voltage collapse in a power system are described. Circuit and system techniques for analyzing voltage collapse that relate it to the changing number of solutions for the power-flow equations, due to slow changes in system parameters are presented. It is shown that to fully analyze voltage collapse for small- and large-disturbance cases,

Simulation of voltage collapse
International Journal of Electrical Power & Energy Systems, 1993 The article analyses the mechanisms of voltage collapse and reaches the conclusion that it is necessary to make use of detailed simulations in order to study real cases. The performance levels required from the simulation programs are established. A summary description of the Eurostag code highlights the program's algorithmic bases.

Estimating the Collapse Point of a Transmission Line in a Developing Power Systems
Arid Zone Journal of Engineering, Technology and Environment, 2023 The trouble with a developing national grid is compounded by the fact that the power system supplies power to a vast number of loads which is fed by a number of generating units sometimes far from the load centers.

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.

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 ...

Optimal coordinated voltage emergency control against voltage collapse
International Journal of Electrical Power & Energy Systems, 2013 Abstract This paper presents a novel model for optimal coordinated voltage emergency control (OCVEC). It takes account of the dynamics of loads and discrete/continuous nature of controls with coordination of dissimilar controls at different geographical locations in order to keep the desired voltage profiles against voltage collapse during an ...
