PROBLEM TO BE SOLVED: To maintain a fixed output by suppressing an output fluctuation of a wind farm.SOLUTION: This control device for a wind power generator group includes: a transmitting/receiving means 51 for receiving operation information sent from wind power generators 11, 12, 13 and transmitting output command information thereto; a central operation control means 41 for receiving the operation information to apply arithmetic processing to an output fluctuation and control the operation of the wind power generator group 100 depending on the output command information transmitted to the wind power generators 11, 12, 13; an output predicting means 53 for predicting a near-future output fluctuation on the basis of the prediction of a near-future wind velocity fluctuation for the wind power generator group 100 in accordance with the operation information; and an energy storage/release command means 54 for storing wind power energy as rotating energy when a total output is greater than a target output. The total output is limited to a value lower than a rated output, and the energy storage/release command means 54 releases the stored rotating energy near a minimum value for a near-future total output when the total output is smaller than the predetermined target output.
