Resumé

— Offshore wind energy capitalizes on the higher
and less turbulent wind at sea. Shallow water sites are profitable
for deployment of monopile wind turbines at water depths of up
to 30 meters. Beyond 30 meters, the wind is even stronger and
less turbulent. At these depths, floating wind turbines become
profitable, capable of accessing unexploited wind resources
while reaching regions of new consumers. However, floating
wind turbines are subject to reduced structural stiffness which
results in instabilities when standard wind turbine control
systems are applied. Based on optimal control, this paper
presents a new minimum thrust control strategy capable of
stabilizing a floating wind turbine. The new control strategy
explores the freedom of variable generator speed above rated
wind speed. A comparison to the traditional constant speed
strategy, shows improvements in structural fore-aft oscillations
and power stability when using the new control strategy.
