Controlling the flow within wind farms, to increase the overall energy capture and to reduce the fatigue loads, is a challenging control problem due to its size and the underlying time-varying dynamics. State-of-the-art wind farm controllers follow the open-loop control paradigm by computing optimal set-points using static models. However, due to the time-varying inflow conditions and uncertain flow...
In this work, the concept of total power optimization for wind farms under wake interaction is presented. A dedicated Computational Fluid Dynamic (CFD) model of the wind based on the numerical solution of the 2D Navier-Stokes equations is implemented in an efficient way by exploiting the sparsity of the involved matrices. Thus, the total power optimization over the farm is performed by incorporating...
