Multipoint Reconstruction of Wind Speeds [PDF]

open access: yesWind Energy Science, 2020
Abstract. The most intermittent behavior of atmospheric turbulence is found for very short time scales. Based on a concatenation of conditional probability density functions (cpdfs) of nested wind speeds increments, inspired by a Markov process in scale, we derive a short-time predictor for wind speed fluctuations around a non-stationary mean value and

Results from a wake-steering experiment at a commercial wind plant: investigating the wind speed dependence of wake-steering performance

open access: yesWind Energy Science, 2021
. Wake steering is a wind farm control strategy in which upstream wind turbines are misaligned with the wind to redirect their wakes away from downstream turbines, thereby increasing the net wind plant power production and reducing fatigue loads ...
