1. A method for optimizing one or more farm-level metrics in a wind farm, the method comprising: identifying an optimization objective and one or more decision variables for optimization; optimizing the optimization objective based on wake-affected wind conditions, power capture values, or damage equivalent load values, to calculate optimum decision variable values for each wind turbine; transmitting the optimum decision variable values to the respective wind turbines; and applying the optimum decision variable values to the respective wind turbines to achieve the optimization objective.
