‘Voltage stability’ simplified

International Journal of Electrical Power & Energy Systems, 1992
Abstract This is not a physical or mathematical explanation or definition of voltage stability. Rather, it shows for a very simple case (to which, however, practically all cases of voltage stability or instability can be reduced) the very simple equations that apply.
