Voltage collapse in power systems [PDF]

open access: yesIEEE 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,
