%X This paper deals with a robust and consistent grid power interface system for permanent-magnet synchronous generator (PMSG) based wind power generation system. The proposed system consists of a generator-side buck-type rectifier and a grid-side impedance source inverter, which is employed as a bridge between the generator and the grid. The proposed system components like PMSG, DC Link, impedance network, inverters are modeled by using MATLAB/SIMULINK. The control strategy for the proposed topology is developed from space-vector modulation and Z-source network operation principles. The unity-power-factor control method is suggested and to establish an optimized control scheme for the generator-side three-switch buck-type rectifier. To extract the maximum power from the wind turbine generator and the power is transferred to the grid system is achieved by adjusting the shoot-through duty cycles of the Z-source network. The performances of the PMSG based WECS has been analyzed and the results are verified.
