Wind Turbine Power Tracking Using Multiple Model Predictive Control

Due to the development of technology and a great demand of energy, researchers try to discover energy sources with lower pollution, so the use of wind power for generatingelectricity has been increasing over last few decades. Nowadays, controller design for a variable speed variable pitchwind turbine is one of the most challenges for engineers.In this paper, a multivariable control strategy based on multiple model predictive control techniques for the control of variablespeed pitch regulated wind turbines in the above-rated wind speed (full region) is proposed. Pitch angle and generatortorque are controlled to reduce loads by producing a rated generator power and turbine speed. The advantages of this control structure are to consider themultivariable nature of the system and using a multiple model structure to deal with the nonlinearity in the system. A 2MW wind turbine is considered to show the good performances brought by the proposed approach by presenting and discussing the simulation results
