T. Vancutsem, AN APPROACH TO CORRECTIVE CONTROL OF VOLTAGE INSTABILITY USING SIMULATION AND SENSITIVITY, IEEE transactions on power systems, 10(2), 1995, pp. 616-622
This paper deals with the diagnosis of voltage collapse situations, fo
llowing large disturbances and/or load increases. A method is proposed
to identify the set of buses where load restoration is responsible fo
r the colla pse a nd to determine the corresponding corrective actions
. It has been implemented in a fast voltage stability simulator, using
sensitivity techniques. Tap changer blocking and load shedding are il
lustrated on a real-life 410-bus system.
