Giyanani, A.H. (author), Savenije, F.J. (author), van Bussel, G.J.W. (author)The IEC standards prescribe an inflow wind field based on models with empirical assumptions to perform load calculations. The use of preview wind speed measurements using nacelle-mounted Lidars allows mitigation of structural loads by suggesting appropriate control action. This relationship is affected by uncertainty in site conditions and...journal article 2018

Kumar, V. (author), Savenije, F.J. (author), van Wingerden, J.W. (author)Increasing demands in decentralized power plants have focused attention on Vertical Axis Wind Turbines (VAWTs). However, accessing high range of power from VAWTs is an impediment due to increased loads on the turbine blades. Here, we derive an optimal pitching action that reduces the periodic disturbance on turbine blades of VAWTs without...conference paper 2018

Huijs, Fons (author), Vlasveld, Ebert (author), Gormand, Maël (author), Savenije, F.J. (author), Caboni, Marco (author), LeBlanc, B.P. (author), Ferreira, Carlos (author), Lindenburg, Koert (author)A semi-submersible Tri-Floater has been designed to support a 6 MW vertical axis wind turbine (VAWT) with active blade pitch control. Due to the low centre of gravity and large allowable floater tilt angle, a relatively small floater can be used to support a VAWT. Coupled simulations including hydrodynamics, mooring system, aerodynamics and...journal article 2018
