Abstract. This paper explores the potential benefits brought by the integration of lidar-assisted control (LAC) in the design of a wind turbine. The study identifies which design drivers can be relaxed by LAC, and by how much these drivers should be reduced by LAC before other conditions become the drivers. A generic LAC load-reduction model is defined and used to redesign the rotor and tower of three turbines, differing in terms of wind class, size and power rating. The load reductions enabled by LAC are used to save mass, increase hub height or extend lifetime. For the first two strategies, results suggest only modest reductions in the levelized cost of energy, with potentially benefits essentially limited to the sole tower of a large offshore machine. On the other hand, lifetime extension appears to be the most effective way of exploiting the effects of LAC.

Short summary
Lidar-assisted control (LAC) is used to redesign the rotor and tower of three turbines, differing in terms of wind class, size and power rating. The load reductions enabled by LAC are used to save mass, increase hub height or extend lifetime. The first two strategies yield reductions in the cost of energy only for the tower of the largest machine, while more interesting benefits are obtained for lifetime extension.
