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.

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 ...
