ABSTRACT

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.

Keywords: Saddle-node bifurcations, PID controller, power systems.

RESUMEN

En este trabajo se presenta la eliminación de una bifurcación de un nodo tipo "Saddle" en un sistema de potencia básica utilizando un controlador PID. Asimismo se presenta el análisis de estabilidad del ángulo del rotor y de su frecuencia que están directamente relacionadas con el problema de colapso del voltaje.
