Wind power generation system and operation control method therof

摘要

A variation in output at an interconnection is reduced. An operation control method for a wind power generation system includes a step of acquiring output data of each wind mill, a step of evaluating correlation of a variation in outputs from adjacent wind mills using the output data, and a step of, when strong correlation appears, changing a phase of the variation in output from one of the adjacent wind mills with a cycle of occurrence of the strong correlation.
