Full envelope wind turbine controller design for power regulation and tower load reduction

The main objective of this thesis is to design controllers for a 2MW wind turbine for power regulation and tower load reduction. Due to the highly stochastic nature of the wind, a wind turbine is exposed to strongly varying loads. More specifically tower loads are a major concern and there is little literature proposing solutions towards their mitigation. One of the objectives of the operation of a wind turbine is to maximize its energy capture in below rated wind speeds through the controller. A thorough assessment of what is possible in a modern MW scale wind turbine is undertaken in this thesis. A full envelope single input single output controller is designed to be used as a benchmark for comparison of the newly proposed coordinating controller which successfully mitigates tower fatigue loads. The design of the newly proposed coordinated controller is thoroughly explored and tested.
