Abstract
Wind energy gains increasing importance around the world. The efficiency and energy conversion systems have been improved due to the advancement of variable speed drive design and control of wind energy systems. For wind turbine systems, the Maximum Power Point Tracking (MPPT) plays a vital role in achieving efficient energy conversion. The MPPT strategy controls the rotor speed by adjusting electromagnetic torque and maximizing the generator’s output power. This thesis evaluates applying the Proportional-Integral (PI) controller and the proposed Model Predictive Controller (MPC) on two different control strategies to fulfill the MPPT of a variable speed wind turbine (VSWT). The methods that identify the modeling of the VSWT are the Direct Speed Measurement (DSM) method and Pitch Angle Control technique (PAC). The MATLAB Simulink is applied for optimizing and implementing these two control methods, incorporating the mentioned controllers. The results are investigated to ensure the performance of the controllers employed with the wind turbine under different operating conditions.
