  11. Another Model Quasi-steady Wind Farm Flow Model Arno Brand, Jan Willem Wagenaar FP7-ICT STREP 224548 / Aeolus

  12. Another Model Model Output qsWFFM • Forward ({ {WS, BPA, RS}iklm, {Power, Loads}iklm) = f( {WSk, WDl, TIm} ) state output external conditions • Inverse ({WSk, WDl, TIm}, {WS, BPA, RS}iklm, {Loads}iklm) = g( {Power}iklm ) external conditions state loads power reference WS = Ambient wind speed WD = Ambient wind direction TI = Turbulence intensity BPA = Blade pitch angle RS = Rotor speed FP7-ICT STREP 224548 / Aeolus
