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

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 ...

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 ...

Wind turbine wakes: exploring the underexplored

Sina Shamsoddin

In this thesis, we aim to contribute to the research on two topics, namely, vertical-axis wind turbines (VAWTs) and wind turbines on topography. In the VAWT part, first, we implement two actuator-type VAWT parameterization models (i.e. the actuator swept- ...

Optimal Control Strategies of Seasonal Storage Devices for District Energy Management

Julien Jocelyn Leprince

The potential energy savings resulting from the cooperative management of community districts, also known as energy hubs, has been widely demonstrated throughout the literature. Various developed predictive control strategies have proven to generate remark ...

Innovative measurement techniques for atmospheric turbulence and wind energy

Fernando Carbajo Fuertes

The measurement of different atmospheric flow quantities is of utmost importance for a correct understanding of most atmospheric phenomena. Researchers and industry in the fields of meteorology and wind engineering demand extensive and accurate measurement ...

Dispatch and Primary Frequency Control with Electrochemical Storage: a System-wise Verification

Mario Paolone, Fabrizio Sossan, Mokhtar Bozorg, Yihui Zuo

Uncertainty levels in forecasting of renewable generation and demand are known to affect the amount of reserve required to operate the power grid with a given level of reliability. In this paper, we quantify the effects on the system reserve and reliabilit ...

Wind Turbine Wake Characterization with Nacelle-Mounted Wind Lidars for Analytical Wake Model Validation

Fernando Porté Agel, Corey Dean Markfort, Fernando Carbajo Fuertes

This study presents the setup, methodology and results from a measurement campaign dedicated to the characterization of full-scale wind turbine wakes under different inflow conditions. The measurements have been obtained from two pulsed scanning Doppler li ...

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 ...

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 ...

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 ...
