This paper presents a new methodology for controlling wind farms in a decentralized framework, where the wind turbines exchange information with their neighbours, and update their own control parameters in order to optimize the total power produced by the wind farm in a time-efficient manner, taking into account effects of wake interaction. The method can be characterized as being model-free si...

Electrical power losses are an important factor when wind farm location and size are selected. The capitalized cost of constant power losses during the life of a wind farm will continue to high levels. During the operation period, a method to determine if the losses meet the r...
