Wind speed dynamical model in a wind farm [PDF]

open access: yesIEEE ICCA 2010, 2010
This paper presents a model for wind speed in a wind farm. The basic purpose of the paper is to calculate approximately the wind speed in the vicinity of each wind turbine in a farm. In this regard the governing equations of flow will be solved for the whole wind farm. In ideal circumstances, the dynamic model for wind flow will be established.

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 ...

Estimation of effective wind speed [PDF]

open access: yesJournal of Physics: Conference Series, 2007
The wind speed has a huge impact on the dynamic response of wind turbine. Because of this, many control algorithms use a measure of the wind speed to increase performance, e.g. by gain scheduling and feed forward. Unfortunately, no accurate measurement of the effective wind speed is online available from direct measurements, which means that it must be

Wind Speed Analysis of Hurricane Sandy [PDF]

open access: yesAtmosphere, 2021
The database of the HWind project sponsored by the National Oceanic and Atmospheric Administration (NOAA) for hurricanes between 1994 and 2013 is analysed. This is the first objective of the current research. Among these hurricanes, Hurricane Sandy was selected for a detailed study due to the number of files available and its social relevance, with ...
