The VAMOS (Validation, Measurement and Optimization of Floating Wind Energy Systems) project is a collaborative project funded by the Federal Ministry for Economic Affairs and Climate Action on the basis of a decision by the German Bundestag. The main objective of the VAMOS project is to close knowledge gaps in the measurement and simulation of floating offshore wind energy system for commercial use. This report gives recommendations on transferring lidar-assisted control technology from bottom-fixed wind turbines to floating wind turbines and gives an example evaluation of the impact on the performance of the floating wind turbine. The report starts by presenting the problems of applying lidar-based wind field reconstruction on floating wind turbines and indicates the key solutions to the problem by comparing different wind field reconstruction methods. Secondly, lidar-assisted control strategies of different technology maturity levels are presented. The improvements required for higher-maturity technologies for floating applications are presented. Lastly, this report assesses the benefits of lidar-assisted control using one of the technically more mature strategies, namely lidar-assisted feedforward and multivariable feedback control, considering a 15 MW floating turbine. |
