Abstract:
Through the last decades, due to environmental issues and to confine CO2 emission and also dependency to the fossil fuels, renewable energy resources has been developed. It’s been expected up to 2035, the renewable energy resources will be scaled three times and among those resources, the wind energy will stand prominently. Out of this king of renewable resource, the horizontal wind turbine has been subjected in this research.The focus of is to design the controller in third of a 2 MW turbine operation by which stable rotor speed and nominal output power to be attained. Besides, to enhance the accuracy of the windturbine profiles, the TURBSIM software (At the National Renewable Energy Laboratory) has been used. The input data for the control system is the generator torque and pitch angle. A two DOF model has been implemented for the controller design and the wind simulation. Moreover, a controller for phase two has been developed as well.The competency of controller has been justified by model predictive control metohs, implemented. Besides, the robustness of the controller against the uncertainties has been investigated and verified
