Analytical Modeling for Prediction of Horizontal-Axis Wind Turbines Power Generation in Wind Farms Based on an Analytical Wake Model [PDF]
Iranica Journal of Energy and Environment, 2022 The development of models that predict power production of wind farms (WFs) by considering the interacting wakes is important; because wakes of the turbines exert a significant influence on power production of turbines, and hence on the layout of wind ...

Experimental validation of analytical wake and downstream turbine performance modelling [PDF]
Journal of Physics: Conference Series, 2018 Wake effects in wind farms can cause significant power losses. In order to reduce these losses layout and control optimization can be applied. For this purpose, simple and fast prediction tools for the wake flow are needed. In the first part of this work, five analytical wind turbine wake models are compared to small-scale turbine wind tunnel ...

A physical wind‐turbine wake growth model under different stratified atmospheric conditions
Wind Energy, 2022 The wind‐turbine wake growth is crucial for wake assessment. At present, it can only be determined empirically, which is the primary source of prediction errors in the analytical wake model, and a physically‐based method is urgently needed. Recently, the

Breakdown of the velocity and turbulence in the wake of a wind turbine – Part 2: Analytical modeling
Wind Energy Science, 2022 Abstract. This work aims at developing an analytical model for the velocity and turbulence in the wake of a wind turbine that takes meandering into account and where the expansion and the meandering of the wake can be independently calibrated. The velocity and turbulence breakdown presented in the companion paper allows a better interpretation of the ...

A simple vortex model applied to an idealized rotor in sheared inflow [PDF]
Wind Energy Science, 2023 A simple analytical vortex model is presented and used to study an idealized wind turbine rotor in uniform and sheared inflow, respectively. Our model predicts that 1D momentum theory should be applied locally when modelling a non-uniformly loaded rotor ...

Comparison of modular analytical wake models to the Lillgrund wind plant
Journal of Renewable and Sustainable Energy, 2020 Efficient and accurate wake models are required for wind plant performance modeling and the suite of engineering processes that support wind plant layout, control, and monitoring. Although many analytical and engineering wake models with low computational costs have been proposed, their ability to represent the power production of large wind plants in ...
