floris.optimization.layout_optimization.layout_optimization_gridded.LayoutOptimizationGridded WARNING Running layout optimization without a WindData object (e.g. TimeSeries, WindRose, WindTIRose). We suggest that the user set the wind conditions (and if applicable, frequencies and values) on the FlorisModel using the wind_data keyword argument for layout optimizations to capture frequencies and the value of the energy production accurately. If a WindData object is not defined, uniform frequencies will be assumed. If use_value is True and a WindData object is not defined, a value of 1 will be used for each wind condition and layout optimization will simply be performed to maximize AEP.
