Effects of wind direction and wind farm layout on turbine wakes and power losses in wind farms: An LES study

A recently-developed large-eddy simulation (LES) framework is validated and used to investigate the effects of wind direction and wind farm layout on the turbine wakes and power losses in wind farms. The subgrid-scale (SGS) turbulent stress is parameterize ...

Volumetric scans of wind turbine wakes performed with three simultaneous wind LiDARs under different atmospheric stability regimes

Fernando Porté Agel, Giacomo Valerio Iungo

Aerodynamic optimization of wind farm layout is a crucial task to reduce wake effects on downstream wind turbines, thus to maximize wind power harvesting. However, downstream evolution and recovery of wind turbine wakes are strongly affected by the charact ...

Optimization of Wind Farm Performance Based on Yaw Angle Control

Fernando Porté Agel, Majid Bastankhah

Inside wind farms, the wakes of upwind turbines result in a significant reduction in power production. Yawing upwind turbines can be used to deflect the wakes away from turbines. Even though this reduces the power production of upwind turbines, it can pote ...

Influence of the Hydraulic System Layout on the Stability of a Mixed Islanded Power Network

François Avellan, Christophe Nicolet, Christian Landry, Stefano Giacomini

Numerical simulation and stability analysis of an islanded power network comprising 40 MW of hydropower, 20 MW of wind power and 60 MW of gas-fired power plant are investigated. First, the modeling of each power plant is fully described. The wind farm is m ...

Interaction between large wind farms and the atmospheric boundary layer

Fernando Porté Agel, Yu-Ting Wu, Hao Lu

Accurate prediction of atmospheric boundary layer (ABL) flow and its interactions with wind turbines is of great importance for optimizing the design and efficiency of wind farms. This study first focuses on recent efforts to develop and validate a large-e ...

An analytical 1-D model for vertical momentum and energy flux through a fully developed wind farm

Fernando Porté Agel, Wei Zhang, Corey Dean Markfort

Wind farms capture momentum from the atmospheric boundary layer (ABL) both at the leading edge and from the atmosphere above. Momentum is advected into the wind farm and wake turbulence draws excess momentum in from between turbines until momentum is only ...

Model based power optimisation of wind farms

Maryam Kamgarpour, John Lygeros

We present a framework for maximising the power output of a wind farm considering wake effects. A parameter representing the total power coefficient of a wind farm is introduced, which quantifies the wind speed deficit due to wake. For any given wake model ...

The effect of atmospheric stability on wind-turbine wakes: A large-eddy simulation study

Fernando Porté Agel, Mahdi Abkar

In this study, large-eddy simulation is used to investigate the influence of atmospheric stability on wind-turbine wakes. In the simulations, tuning-free Lagrangian scale-dependent dynamic models are used to model the subgrid-scale turbulent fluxes, while ...
