Simulation of voltage collapse

open access: yesInternational 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.
