A wind farm output control device includes a potential estimator estimating a maximum electrical energy outputtable by each wind power generation device, a control amount determiner determining, based on the estimated maximum power amount, a control amount for an effective power of each wind power generation device and/or a reactive power thereof in a wind farm, and a control amount distributor distributing the control amount based on an available power generation amount of each wind power generation device. The potential estimator estimates the maximum power amount based on a pitch angle of blades, an angular speed deviation of a power generator, and a conversion loss of the wind power generation device. Within the range of the estimated maximum power amount, the control amount for the output by the wind farm is distributed within a range where each wind power generation device is outputtable according to the wind condition.

Output control device, method and program for wind farm

An output by a wind farm including multiple wind power generation devices is controlled by an output control device. To control the output, (1) a potential estimator estimates an outputtable maximum power amount by each wind power generation device, (2) a control amount determiner determines a control amount of the whole wind farm based on the maximum power amount estimated by the potential estimator, (3) a control timing adjuster adjusts a control timing of the control amount of the whole wind farm, (4) a control amount distributer distributes the control amount having undergone the control timing adjustment based on an available power generation amount of each wind power generation device.
