Control design for floating wind turbines: a novel feedback control structure

The generator speed feedback control of onshore wind turbines, via the pitch controller to feather the blades, is well established, but employing the same controller gains with floating offshore wind turbines causes the turbines to become unstable. Such instability is attributed...

Gaussian process surrogate modeling for efficient controller tuning and fatigue load prediction of the helix wake-mixing method

Abstract. Wind farms experience reduced power production and elevated structural loading due to wake interactions. Wake-mixing control techniques, which dynamically excite upstream turbine wakes to accelerate recovery, have demonstrated promising improvements in downstream power...

Multi-strategy wind farm control: alternating wake steering and helix wake mixing on a large-scale wind farm

Abstract. Wind farm flow control mitigates wake effects by adjusting turbine settings to improve overall farm performance rather than the output of each turbine. Wake steering is an established wind farm flow control approach, while the helix method has recently emerged as a prom...
