Voltage and energy utilization enhancement in a stand-alone WECS using a fuzzy logic controlled PWM-switched dynamic capacitor compensation

A novel sinusoidal PWM switched power filter (SPF) and dynamic voltage compensation (DVC) scheme is studied in this work. A real time dynamic voltage, power and generator velocity error tracking based fuzzy logic controller (FLC) is used to stabilize the stand alone wind energy conversion scheme (WECS) comprising an induction generator. The novel dynamic error driven FLC controlled scheme serves as a voltage stabilization regulator and energy utilization enhancement compensator.
