Abstract
Voltage stability has become a very importante issue
of power systems analysis. This paper discusses some important
aspects related to voltage stability indices in electric power
systems. Some techniques previously studied in the literature
are analyzed and a comparison of the performance of several
indices is presented. The effectiveness of the analyzed methods
are demonstrated through numerical studies in IEEE 14 busbar
test system, using several different scenarios of load increas
