A Distributed Power Coordination Scheme for Fatigue Load Reduction in Wind Farms

In English Wind turbines operating in wind farms are coupled by the wind flow. This coupling results in increased turbulence levels for
downwind turbines, and consequently higher maintenance costs. In this paper, we consider a scenario where a wind farm is asked to produce less than maximum power. The objective is to minimize fatigue loads on the turbines, while maintaining the desired power production. We show how this can be achieved by coordinating neighboring turbines. The result is a control structure where each turbine only need to communicate with a limited set of neighboring turbines. Moreover, the synthesis of
the controllers is also distributed.
