This dissertation investigates the use of the permanent magnet wind generator as a means for damping dynamic inter-area oscillations in multi-area power systems. The feedback loops control are investigated to damp the inter-area oscillations. Two methods of controls are discussed to modulate the power based on damping torque control and H-infinity design methodology. The controller uses as feedback the frequency deviation of the local power system area and applies effective control on the wind generator rotor speed, blade pitch angle and dc link voltage to provide sufficient power modulation at the output of the generator to damp inter-area oscillations.
