Multi-Objective Wind Farm Layout Optimization with unconstrained Area Shape

Fernando Porté Agel, Nicolas Otto Kirchner Bossi

It is well known that turbine wakes are responsible for considerable power losses in a wind farm. In the last two decades Wind Farm Layout Optimization (WFLO) has been extendedly used to model the minimization of such wake effects in the attempt to maximiz ...

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

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

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 ...

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 ...

Potential and uncertainty of wind energy in the Swiss Alps

Albertus Christiaan Kruyt

Switzerland has committed itself to an ambitious energy strategy. It aims to replace the exist- ing nuclear generation capacity with predominantly indigenous renewable resources. Wind power could play a significant role in this transition, yet the wind res ...

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 ...

Optimal placement of inertia and primary control in high voltage power grids

Philippe René Joseph Jacquod

The energy transition's ultimate goal is to meet energy demand from human activities sustainably. Accordingly, the penetration of new renewable energy sources (RES) such as photovoltaic panels and wind turbines is increasing in most power grids. In their c ...

Coherent Structure Interaction During Unsteady Separation

Karen Ann J Mulleners

Unsteady flow separation in rotationally augmented flow fields plays a significant role in the aerodynamic performance of industrial rotors, including wind turbines. Current computational models underestimate the aerodynamic loads due to the inaccurate pre ...

Short-Term Forecasting of Wake-Induced Fluctuations in Offshore Wind Farms

Arslan Salim Dar

The increasing share of offshore wind energy traded at the spot market requires short term wind direction forecasts to determine wake losses and increased power fluctuations due to multiple wakes in certain wind directions. The information on potential pow ...
