Wind farm axial-induction factor optimization for power maximization and load alleviation

The focus of this work is on addressing and solving the mixed-objective optimization problem for the operation of a wind farm, which considers both power maximization and mechanical load reduction. The proposed strategy provides the opportunity to operate the wind farm in different ways, depending on whether maximizing power production or reducing turbines wear is more relevant. We incorporate the power maximization objective by considering the mean value of the produced power; the load reduction is divided in two cases, i.e., extreme loads and fatigue damage, incorporated via the thrust force and the thrust force deviations in the cost function, respectively.
