Abstract

This talk overviews a wind farm control technique based on turbine repositioning, which is applicable exclusively to floating offshore wind turbines. The wind turbines are repositioned to modify the wind farm layout based on the wind condition and the power demand, in order to maximize the wind farm efficiency. The repositioning mechanism which manipulates the aerodynamic force by means of conventional wind turbine control inputs is explained. Potential advantages of the turbine repositioning for wind farm control are demonstrated in simulations using the medium-fidelity wind farm simulator FAST.Farm developed by the National Renewable Energy Laboratory (NREL) in the United States. Finally, potential future research directions in this wind farm control technique are provided.
