Beschreibung
Zusammenfassung:	An output control device for a wind farm which includes n number of wind turbines, n being an integer of two or more, is provided with: a WTG output obtaining unit for obtaining a current output P i of each of the wind turbines where i=1,···,n; an extractable output calculation unit for calculating an extractable output Pmaxi for each of the wind turbines where i=1,···,n, the extractable output Pmaxi being energy extractable from wind energy; a potential output calculation unit for calculating a potential output Ppoti of each of the wind turbines based on a difference between the extractable output Pmaxi and the current output Pi of each of the wind turbines where i=1,···,n; and a WTG output determination unit for determining an output command value of each of the wind turbines so that a total output P WF of the wind farm becomes closer to an output target value P WF . The WTG output determination unit is configured to assign an output increase amount to each of the wind turbines based on the potential output Ppoti of each of the wind turbines and to determine the output command value based on the output increase amount, when the output target value P WF of the wind farm is greater than the total output P WF of the wind farm.
