Commande et stabilite d’un systeme electro-energetique

Abstract

The world is always in need for energy and a major part of it is used in its electrical form. Stability problems are mainly those of synchronous machines which produce almost all of the electric energy. New control techniques are used to push farther away power system stability limits. In our work, we propose a control methodology, combining synergetic control and fuzzy logic type-2 systems. Four different control strategies have been simulated and their performances have been compared to those of the proposed control strategy. This control strategy has been applied to a power system stability study of a synchronous machine connected to an infinite bus through a transmission line and to a multi-machine power system. The effectiveness of the proposed control strategy has been verified using Lyapunov criterion and validated by simulation.
