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 ...

Mean and turbulent kinetic energy budgets inside and above very large wind farms under conventionally-neutral condition

Fernando Porté Agel, Mahdi Abkar

In this study, large-eddy simulations (LES) is combined with a turbine model to investigate all the terms in the budgets of mean and turbulent kinetic energy (TKE) inside and above very large wind farms. Emphasis is placed on quantifying the relative contr ...

Large Eddy Simulation of Vertical Axis Wind Turbine Wakes

Fernando Porté Agel, Sina Shamsoddin

In this study, large eddy simulation (LES) is combined with a turbine model to investigate the wake behind a vertical-axis wind turbine (VAWT) in a three-dimensional turbulent flow. Two methods are used to model the subgrid-scale (SGS) stresses: (a) the Sm ...

Effects of Positive versus Negative Yaw Angles on Wind-Turbine Performance: An Application of BEM Theory

Fernando Porté Agel, Majid Bastankhah

Wind-turbine wakes have negative effects on wind-farm performance. They are associated with: (a) the velocity deficit, which reduces the generated power of downwind turbines; and (b) the turbulence level, which increases the fatigue loads on downwind turbi ...

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 ...

Optimization of an Airborne Wind Energy System Using Constrained Gaussian Processes

Colin Neil Jones, Ioannis Lymperopoulos, Sanket Sanjay Diwale

Wind resources tend to be significantly stronger and more consistent with increasing altitude. This effect creates a potential for power generation that can be reaped by an Airborne Wind Energy system positioned at elevations exceeding the height of conven ...

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 ...
