The Wind Power System is comprised of a blade, a PMSG, and three back-to-back converters and filters. Mechanical torque produced from the wind is converter into electrical energy through a PMSG. The produced electrical energy is transferred to the dc-link capacitor through the machine-side converters. The transferred dc-link electrical energies are supplied to the grid through the grid-side inverters. The machine-side converters perform the torque control for Maximum Power Point Tracking (MPPT) The grid-side inverters control not only the dc-link voltage but also the power factor of the grid-side to transfer the generated energy efficiently.
