Optimisation des paramètres d’un FACTS shunt pour l’amélioration de la stabilité transitoire d’un système électrique

Abstract

The use of power systems as close to their operating limits can cause instability if a disturbance is occurred. The damping of the system’s oscillations can be obtained by conventional means such as voltage and speed regulation but also by FACTS devices (Flexible AC Transmission System). These devices are increasingly used in power systems. In this work, the SVC (Static Var Compensator) was sized utilizing the optimization algorithms to improve power system transient stability. The proposed approach is tested on a single machine infinite bus system and on a multi machine power system. The optimal design of the compensator provides a better improvement of transient stability.
