Control scheme of PMSG based wind turbine for utility network connection

With the growing of electrical energy demand, wind energy gains higher potential and plays a vital role in energy sectors. Direct driven permanent magnet synchronous generator (PMSG) with a full size back-to-back converter set is one of the promising technologies employed with wind power generation. This paper focuses on developing a control scheme of PMSG-based wind turbines to obtain maximum wind power extraction and meet network code requirements. Comprehensive models of wind speed, wind turbine, PMSG and power electronic converters along with their control schemes are implemented in MATLAB/SIMULINK environment. Simulation results show the feasibility and robustness of the proposed control schemes for PMSG based wind turbines.
