Voltage Collapse Prediction Using Artificial Neural Network
Engineering Proceedings, 2023 Voltage instability is a serious condition that can occur in a power system. An imbalance in reactive power, inadequate utilization of voltage control devices, loss of a component or an abrupt rise in load demand can cause this entire disturbance which ...

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.
