چکیده

Power systems form one of the largest and most complex technical systems. Changes of load parameters may lead to so called bifurcations, resulting in nonlinear phenomena like voltage collapse or interarea oscillations. Special software tools are able to simulate these systems and to identify bifurcations. This paper presents a systematic approach to determine gain factors of Flexible AC Transmission Devices (FACTS) considering changes of load parameters. This approach is applied to two different power system models. Copyright IFAC 2005
