Multi-rotor Wind Farm Layout Optimization

Fernando Porté Agel, Nicolas Otto Kirchner Bossi

Multi-rotor wind turbines have shown a faster wake recovery than equivalent single-rotor turbines. In this work the potential benefit of a wind farm with multi-rotor turbines is assessed through the optimization of the turbine positions using the CEGA wind ...

A momentum-conserving wake superposition method for wind farm power prediction

Fernando Porté Agel, Haohua Zong

Analytical wind turbine wake models and wake superposition methods are prevailing tools widely adopted by the wind energy community to predict the power production of wind farms. However, none of the existing wake superposition methods conserve the streamw ...

Wind farm power optimization via yaw angle control: A wind tunnel study

Fernando Porté Agel, Majid Bastankhah

Yaw angle control is known nowadays as a promising and effective technique to mitigate wake effects in wind farms. In this paper, we perform wind tunnel experiments to study the performance of a model wind farm with five turbine rows under a wide variety o ...

Large-Eddy Simulation of Yawed Wind-Turbine Wakes: Comparisons with Wind Tunnel Measurements and Analytical Wake Models

Fernando Porté Agel, Mou Lin

In this study, we validated a wind-turbine parameterisation for large-eddy simulation (LES) of yawed wind-turbine wakes. The presented parameterisation is modified from the rotational actuator disk model (ADMR), which takes account of both thrust and tange ...

Characterization of Wind Turbine Wakes with Nacelle-Mounted Doppler LiDARs and Model Validation in the Presence of Wind Veer

Fernando Porté Agel, Fernando Carbajo Fuertes, Corey Dean Markfort, Mohsen Vahidzadeh, Peter Andreas Brugger

Accurate prediction of wind turbine wakes is important for more efficient design and operation of wind parks. Volumetric wake measurements of nacelle-mounted Doppler lidars are used to characterize the wake of a full-scale wind turbine and to validate an a ...

Multirotor UAV-based platform for the measurement of atmospheric turbulence: validation and signature detection of tip vortices of wind turbine blades

Fernando Porté Agel, Lionel Wilhelm, Fernando Carbajo Fuertes

The present study describes the development of a technique for the measurement of atmospheric turbulence and temperature at a point in space based on the integration of a fast-response multi-hole pressure probe and a thermocouple with an inertial measureme ...

Wind Turbine Wakes in Directionally Varying Wind Shears

Fernando Porté Agel, Mahdi Abkar

In the atmospheric boundary layer, the Coriolis force associated with the Earth’s rotation induces a spanwise wind shear in addition to the wall-normal one leading to a continuous change in wind direction with height. The spanwise wind shear in directional ...

Wind Energy Prediction in Highly Complex Terrain by Computational Fluid Dynamics

Jiannong Fang, Fernando Porté Agel, Daniel Jacob Tabas

With rising levels of wind power penetration in global electricity production, the relevance of wind power prediction is growing. More accurate forecasts reduce the required total amount of energy reserve capacity needed to ensure grid reliability and the ...

Analysis of control-oriented wake modeling tools using lidar field results

Fernando Porté Agel

The objective of this paper is to compare field data from a scanning lidar mounted on a turbine to control-oriented wind turbine wake models. The measurements were taken from the turbine nacelle looking downstream at the turbine wake. This field campaign w ...

Using a Virtual Lidar Approach to Assess the Accuracy of the Volumetric Reconstruction of a Wind Turbine Wake

Fernando Porté Agel, Fernando Carbajo Fuertes

Scanning Doppler lidars are the best tools for acquiring 3D velocity fields of full scale wind turbine wakes, whether the objective is a better understanding of some features of the wake or the validation of wake models. Since these lidars are based on the ...

Experimental investigation of vertical-axis wind-turbine wakes in boundary layer flow

Fernando Porté Agel, Vincent François-Charles Rolin

In this experiment, a small scale vertical-axis wind-turbine (VAWT) is immersed in a boundary-layer in a wind tunnel and stereo particle image velocimetry is employed to quantify the 3D characteristics of the wake. The measurements show that the wake is st ...

A model for the effect of pressure gradient on turbulent axisymmetric wakes

Fernando Porté Agel, Sina Shamsoddin

Turbulent axisymmetric wakes under pressure gradient have received little attention in the literature, in spite of their fundamental and practical importance, for example, in the case of wind turbine wakes over topography. In this paper, we develop an anal ...

Realistic Wind Farm Layout Optimization through Genetic Algorithms Using a Gaussian Wake Model

Fernando Porté Agel, Nicolas Otto Kirchner Bossi

Wind Farm Layout Optimization (WFLO) can be useful to minimize power losses associated with turbine wakes in wind farms. This work presents a new evolutionary WFLO methodology integrated with a recently developed and successfully validated Gaussian wake mo ...

Wind turbine wakes over hills

Fernando Porté Agel, Sina Shamsoddin

Understanding and predicting the behaviour of wind turbine wake flows over hills is important for optimal design of wind-farm configurations on topography. In this study, we present an analytical modelling framework together with large-eddy simulation (LES ...

A Simple Physically-Based Model for Wind-Turbine Wake Growth in a Turbulent Boundary Layer

Fernando Porté Agel, Wai Chi Cheng

The growth rate of wind-turbine wakes in the atmospheric boundary layer is a key parameter in analytical models used to predict wind-turbine wakes and their effects in wind farms. To date, the turbine-wake growth rate is determined empirically, owing to ou ...

Variability of wind turbine noise over a diurnal cycle

Fernando Porté Agel, Ka Ling Wu

The diurnal variation of atmospheric conditions over land has a significant effect on the wind and temperature distributions which greatly influence the generation and propagation of wind turbine aerodynamic sound. In this paper, a fully consistent unstead ...
