Applications of a moving surface drag model: From Stokes waves to offshore wind farms
Manuel Ayala, Zein Sadek, Raul. B Cal +2
Offshore wind farms operate within the marine atmospheric boundary layer, where ocean waves can modify air-sea momentum transfer, turbine inflow, and wake recovery. Wave-resolved s…
Wind farms as sensor arrays of turbulent boundary layer spatio-temporal flow structure
Manuel Ayala, Dennice Gayme, Charles Meneveau
Temporal fluctuations of wind farm-generated power arise from the interaction between atmospheric turbulence, turbine properties, and wind-farm layout. However, accurately characte…
From Cut-In to Rated: Multi-Region Floating Offshore Wind Farm Control for Secondary Frequency Regulation
Stephen Ampleman, Dennice F. Gayme
This paper describes a multi-region control framework for floating offshore wind farms. Specifically, we propose a novel generator torque controller that regulates rotor speed in R…
Wind Farm Dynamics over a Diurnal Cycle: Analysis of a Comprehensive Large Eddy Simulation, Web-Services Accessible Dataset
Shuolin Xiao, Xiaowei Zhu, Ghanesh Narasimhan +2
The atmospheric boundary layer undergoes significant changes throughout a diurnal cycle, affecting wind turbine performance and wakes in wind farms. Wind farm Large Eddy Simulation…
