On the feasibility and limits of extreme load reduction for wind turbines via advanced sensing: A LIDAR case study

This paper discusses some strategies that may be used to reduce extreme loads suffered by a wind turbine, by means of specific control actions based on wind speed measurements taken with a light detection and ranging device. Comparative results for a fully detailed wind turbine model are presented, in which the effectiveness of these strategies is demonstrated for the entire set of ultimate design load cases specified by the IEC61400-1 Ed. 2 standard.
