\[0v_ag<v_cinorv_ag>v_cout\]\[PGwt=(a*v_ag^3+b*P_rated)v_cin\le v_ag\le v_N\]\[P_ratedv_N\le v_ag\le v_cout\]Here Prated is the maximum power that can be generated through WT. Vcout The wind speed is maximum. Fixes a and b are a function of the minimum wind speed Vcin and the nominal wind speed , which are calculated as follows:
