    摘要: A method for controlling a wind power park is disclosed, comprising the steps of: collecting information relating to meteorological conditions at the location of the wind power park, estimating for each of a plurality of the wind turbines the production costs per unit energy at different load levels of the respective wind turbine, collecting information from a utility grid operator relating to energy prices and possible requirements relating to the amount of power delivered from the wind power park to the utility grid, controlling the wind power park by deciding on a total amount of power to be delivered from the wind power park and distributing the decided power production between individual wind turbines, and repeating the above steps in order to obtain a dynamic control of the wind power park. Further, a wind power park being controlled by such method is disclosed.
