A Large Eddy Simulation framework to assess wind farm power maximization strategies: Validation of maximization by yawing

Recently, there has been an increasing interest in the academic community as well as in the industrial sector about the operation and control of a wind farm at a farm level. This new paradigm has different purposes, from maximizing power production through wake modulation to active power control. The former has been extensively analyzed with numerical or physical modelling, finding in general an improvement in the power production by yawing the wind turbine rotors. The aim of the present paper is to compare both approaches, by taking into account results from state of the art numerical simulations and wind tunnel campaigns. A case with three model wind turbines subject to an atmospheric boundary layer like in flow condition will be studied.
