کنترل مد لغزشی فازی بر مبنای ژنراتور القایی دو سو تغذیه WECS با ذخیره انرژی چرخ لنگر

In this paper the so-called sliding-mode control (SMC) technique used with fuzzy control is applied to control a variable speed wind energy conversion system (WECS) with a doubly fed induction generator (DFIG). The paper also points out interesting performances of the double-fed induction machine (DFIM) used as a flywheel energy storage system (FESS). In fact, adjusting the rotor speed can allow the induction machine to release kinetic energy to the power system or to absorb this energy from the utility grid. The DFIM enables decoupled control of system active and reactive powers in both steady and transient states. The effectiveness of the proposed DFIG-based WECS control approach along with FESS is demonstrated with computer simulation results
