Power output control device, method and program for wind farm

摘要

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 distributer 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.
