Time-adaptive wind turbine model for an LES framework

Varun Sharma, Michael Lehning, Marc Parlange, Marc Calaf Bracons

Most large-eddy simulation studies related to wind energy have been carried out either by using a fixed pressure gradient to ensure that mean wind direction is perpendicular to the wind turbine rotor disk or by forcing the flow with a geostrophic wind and ...

Near-inertial waves in Lake Erie

Damien Bouffard

Near-inertial (Poincare) waves with a period T-p similar to 17 h are the dominant wind-induced internal wave motions in central Lake Erie and consequently have a substantial influence on lake circulation, mixing and biogeochemistry. However, due to the com ...

Improved path following for kites with input delay compensation

Colin Neil Jones, Ioannis Lymperopoulos, Sean Costello, Nikitas Rontsis

In kite power systems, substantial input delay between the actuator and the tethered kite can severely hinder the performance of the control algorithm, limiting the capability of the system to track power-optimal loops. We propose a method that deals with ...

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 ...

A Large Eddy Simulation Study for upstream wind energy conditioning

Varun Sharma, Marc Parlange, Marc Calaf Bracons

The wind energy industry is increasingly focusing on optimal power extraction strategies based on layout design of wind farms and yaw alignment algorithms. Recent field studies by Mikkelsen et al. (Wind Energy, 2013) have explored the possibility of using ...

Mountain passes are potentially advantageous sites for the deployment of wind turbines because of road links and electrical transmission infrastructure. However, relatively little is known about wind characteristics and turbine response in these environmen ...

An Agent-Based Approach to Virtual Power Plants of Wind Power Generators and Electric Vehicles

Matteo Vasirani

Wind power is gaining in significance as an important renewable source of clean energy. However, due to their inherent uncertainty, wind generators are often unable to participate in the forward electricity markets like the more predictable and controllabl ...

In wind farms, the separation distance among wind turbines is mainly determined by the downstream recovery of wind turbine wakes, which affects in turn power production and fatigue loads of downstream turbines. Thus, the optimization of a wind farm relies ...
