Abstract

Energy shortage and global warming issues are among key world challenges in the 21st Century. Wind energy is a renewable clean source, which can reduce carbon dioxide emission. Economical electric energy generation using wind energy production has been rapidly growing for the last two decades. However, the integration of large wind scheme
can pose inherent security and power quality problems. The paper presents dynamic simulation of a novel stabilization scheme using a coordinated tri loop error driven controller. The Wind Energy Scheme comprises three key parts. The wind farm, induction generator, Modulated Power Filter compensator MPFC and hybrid System Load. The distribution grid-wind integrated AC system feeding the hybrid load is to be stable and efficient. The integrated wind-grid scheme with all subsystems has been digitally simulated using the Matlab Simulink/Sim-Power software environment. The modulated filter compensator scheme with the coordinated dynamic error driven hybrid controller was fully validated.
