Influence de la commande d’une GADA des systèmes éoliens sur la stabilité des réseaux électriques

Abstract

The main characteristic of wind resides in its variability, therefore no « dispatch able», it is why, it is important to value the impact of the wind farms on the stability on the electric networks and in particular, on her transient stability following a given disturbance. After a brief recall of the concepts and equations governing the working of a wind system, this document raises of the art state of the different machines - converters used in the wind energy, followed of the transient stability studies on electric networks. This work presents the model of wind turbine and the machines used in this system. The simulation achieved under Matlab environment while using the PSAT. The simulations consists to compare the variations of the conditions of the transient stability of a system electro energing, and the impact of integration the control of wind farms functions in fixed and variable speed. In this work, the proposed model demonstrates the impact of integration of the wind farm in the electric network and permits to estimate the characteristic dynamic of the transient stability in an electrical system.
