On Wind Directions Estimated by Nacelle Lidar Under Different Reconstruction Methods
Wind Energy, Volume 29, Issue 3, March 2026.ABSTRACT The wind direction is closely linked to the power performance and structural loads of wind turbines. Conventional nacelle‐mounted vanes or sonic anemometers face errors associated with airflow distortions caused by turbine blades. Nacelle‐mounted lidar systems offer line‐of‐sight speed measurements from multiple positions ahead of the rotor ...

Flow and wakes in large wind farms in complex terrain and offshore [PDF]
, 2008 Power losses due to wind turbine wakes are of the order of 10 and 20% of total power output in large wind farms. The focus of this research carried out within the EC funded UPWIND project is wind speed and turbulence modelling for large wind farms ...

A concurrent precursor inflow method for Large Eddy Simulations and applications to finite length wind farms [PDF]
, 2014 In order to enable simulations of developing wind turbine array boundary layers with highly realistic inflow conditions a concurrent precursor method for Large Eddy Simulations is proposed. In this method we consider two domains simultaneously, i.e.

Wind Energy, Volume 29, Issue 3, March 2026.ABSTRACT Wind energy's intermittency poses significant challenges for power grid stability. Existing forecasting methods exhibit notable limitations: traditional machine learning models struggle with long‐term temporal dependencies, while deep learning approaches often overlook spatial relationships among turbines.

Spatial Variability of Sea State in the German Bight and Influence of Offshore Wind Farms
Wind Energy, Volume 29, Issue 3, March 2026.ABSTRACT Offshore wind farms are growing worldwide and increase the source of renewable energy. However, as the extent and density of offshore wind farms increase, there is growing importance to understand the interactions with physical systems and the marine environment, in particular, the sea state.

Evaluation of an offshore wind farm computational fluid dynamics model against operational site data [PDF]
, 2019 Modelling wind turbine wake effects at a range of wind speeds and directions with actuator disk (AD) models can provide insight but also be challenging. With any model it is important to quantify the level of error, but this can also present a challenge ...

Cold Climate Wind: Challenges, Technological Solutions and Policy
WIREs Energy and Environment, Volume 15, Issue 1, March 2026.Operating wind farms in cold climates creates unique challenges for turbine designers, owners, and operators. Solving these challenges requires specific technological and policy solutions at all levels. ABSTRACT Cold‐climate wind power represents a major subset of onshore global capacity, with approximately one third of existing installations located ...
