ROSAS, D.; AMARO, C. e ALVAREZ, J.. Control of a saddle node bifurcation in a power system using a PID controller. J. appl. res. technol [online]. 2003, vol.1, n.1, pp.94-102. ISSN 2448-6736.
In this work, we present the elimination of a saddle-node bifurcation in a basic power system using a PID controller. In addition, a stability analysis of the rotor angle and its frequency, which are directly related to voltage collapse problem, is presented.
Palavras-chave : Saddle-node bifurcations; PID controller; power systems.
