Abstract :
A maximum power point tracking (MPPT) controller for variable speed wind energy conversion system (WECS) is proposed. The proposed method, without requiring the knowledge of air density, wind speed and turbine parameters, generates at its output the optimum speed command for speed control loop of rotor flux oriented vector controlled grid side inverter control system using only the instantaneous active power as its input. The optimum speed commands which enable the WECS to track peak power points are generated in accordance with the variation of the active power output due to the change in the command speed generated by the controller. The concept is analyzed in a 2MW direct drive variable speed permanent magnet synchronous generator (D-PMSG) WECS with back-to back IGBT frequency converter. Vector control of the generator side rectifier is realized in the grid voltage vector reference frame. Confirmation of models and control schemes is performed by using the MATLAB/Simulink environment.
