Etude de l’importance du stabilisateur de système de puissance (PSS) en présence des fermes éoliennes à vitesse variable

Abstract

This thesis aims to study the impact of power systems stabilizers (PSS) on power systems stability including wind systems. The study was carried for a doubly fed induction machine based wind farm (DFIG). Different types of PSS (conventional, multi-bands and Fuzzy) have been studied and a compared between them. Optimization procedure was adopted to calculate Fuzzy Logic PSS in order to get better response than the conventional and the multi-bands PSS. In this work, the best placement of the PSS on different generators has been taken in consideration. The obtained results show that the FPSS improves well the power system stability than the conventional and the multi-bands Key Words: Power system, stability, PSS, wind farm, multi-bands, fuzzy.
