Integrated Design and Experimental Validation of a Fixed-Pitch Rotor for Wind Tunnel Testing
Energies, 2023 In this paper we report about the design and validation of a 1.2 m wind turbine rotor with fixed blade pitch. The wind turbine is a scaled version of the DTU 10 MW. Integrated design of dimensional scaling laws, blade aerodynamics, and turbine control is

Adaptive Signal Processing Strategy for a Wind Farm System Fault Accommodation [PDF]
, 2018 In order to improve the availability of offshore wind farms, thus avoiding unplanned operation and maintenance costs, which can be high for offshore installations, the accommodation of faults in their earlier occurrence is fundamental.

Journal of Physics: Conference Series, 2015 A team of researchers from the National Renewable Energy Laboratory and Statoil used large-eddy simulations to numerically investigate the merging wakes from upstream offshore wind turbines. Merging wakes are typical phenomena in wind farm flows in which neighboring turbine wakes consolidate to form complex flow patterns that are as yet not well ...

Region-Based Convolutional Neural Network for Wind Turbine Wake Characterization in Complex Terrain
Remote Sensing, 2021 We present a proof of concept of wind turbine wake identification and characterization using a region-based convolutional neural network (CNN) applied to lidar arc scan images taken at a wind farm in complex terrain.

Asset Redeployability and Biodiversity Risk
Business Strategy and the Environment, EarlyView.ABSTRACT We examine how asset redeployability influences a firm's exposure to biodiversity risk. Our empirical analysis provides robust evidence that firms possessing greater levels of redeployable assets exhibit significantly lower biodiversity risk.

Towards Identifying Contribution of Wake Turbulence to Inflow Noise from Wind Turbines
E3S Web of Conferences, 2015 Downstream turbines in a wind farm often operate under the influence of wakes from upstream turbines. Aerodynamic losses and aeromechanical issues (stochastic loads) associated with such wake-turbine interactions have been investigated before.
