38. Optimization Method of a Wind Turbine Blade Based on Proper Generalized Decomposition

The power generated by wind turbines is considered as to be clean. Wind energy is becoming a priority, among renewable energies, it is considered as a mature and most economical technology after hydroelectricity. The aim of this work is to develop a method for optimizing the aerodynamics shape of the wind turbine blade. An optimization approach will be adopted and applied. To have the shape that will maximize the production of the power of the wind turbine. So our objective is to design the optimal wind turbine blade shape by selecting the optimal airfoil at each rib station along the spanwise direction. The steps of this work consists in developing an optimization method by means of Proper Generalized Decomposition as a calculation tool through the implementation of PGD code on MATLAB starting from Blade Element Theory, that is to say our sought solution is to maximize the power at each rib station, so we will obtain the formulation of the power based on the separation of the coordinates, our coordinates here will be the relative air velocity, chord, the radius r, and the coefficient of the tangential force Ct. With this formulation we will be able to designate which values of Ct generate a maximum power, what will allow us to pick up the best airfoil. So through this method we will open the possibility on the integration of any desired control parameter and monitor the power, to have in the end several optimal models of wind turbine blades.
