Kröger, Lars (author), Frederik, J.A. (author), van Wingerden, J.W. (author), Peinke, Joachim (author), Hölling, Michael (author)A wind tunnel experiment is presented which combines the use of controlled turbulent inflow conditions and a two-bladed model wind turbine utilizing a new control strategy called subspace predictive repetitive control (SPRC). The validation of the performance of SPRC was made under turbulent inflow conditions generated by an active grid. The...conference paper 2018

Frederik, J.A. (author), Kröger, Lars (author), Peinke, Joachim (author), Hölling, Michael (author), van Wingerden, J.W. (author)To reduce the cost of wind energy, it is essential to reduce loads on turbine blades to increase lifetime and decrease maintenance cost. To achieve this, Individual Pitch Control (IPC) received an increasing amount of attention in recent years. In this paper, a data-driven IPC algorithm called Subspace Predictive Repetitive Control (SPRC) is...conference paper 2018

(author), Morthorst, Poul Erik (author), Skytte, Klaus (author)The European Academy of Wind Energy (eawe), representing universities and institutes with a significant wind energy programme in 14 countries, has discussed the long-term research challenges in wind energy. In contrast to research agendas addressing short- to medium-term research activities, this eawe document takes a longer-term perspective,...review 2016
