Abstract

This work provides a comprehensive review of the most recent advancements in the planning, execution, and analysis of wind measurements performed with nacelle-mounted wind Doppler lidars. The recent development of lidar systems for wind speed measurement has allowed unprecedented insights into the dynamics of the wind flow around wind turbines. In particular, lidars have been increasingly installed on top of turbine nacelles to probe the flow at altitudes relevant for wind energy harvesting. The need to balance the enhanced capabilities and limitations of lidars compared to traditional anemometry has given rise to a broad variety of approaches for scan design and wind reconstruction, which we discuss in this review. We give particular emphasis to identifying common guidelines and gaps in the available literature with the aim of providing guidance to wind energy researchers on this cutting-edge experimental technique
