Optimization of Wind Farm Performance Based on Yaw Angle Control

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 ...

Near-wake instability and sensitivity analysis of wind turbines immersed in the atmospheric boundary layer

Fernando Porté Agel, François Gallaire, Giacomo Valerio Iungo, Francesco Viola

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 ...

A robust fault detection and isolation filter for a horizontal axis variable speed wind turbine

Maryam Kamgarpour, Bratislav Svetozarevic

We develop a robust fault detection and isolation (FDI) technique in the presence of measurement noise and apply it to the horizontal axis variable speed wind turbine. In the first part, we provide a nonlinear model of the wind turbine in the form of diffe ...

Quasi-stationary optimal control for wind farm with closely spaced turbines

Tomislav Horvat, Mahsa Parsapour

Modern wind farms typically comprise a large number of wind turbines spread on a relatively small area. The closely spaced turbines are aerodynamically coupled since they share the common energy resource. The aerodynamical coupling is described by the wake ...

Active Learning of Multi-Index Function Models

Volkan Cevher, Hemant Tyagi

We consider the problem of actively learning \textit{multi-index} functions of the form

f(x) = g(Ax)= \sum_{i=1}^k g_i(a_i^Tx)

from point evaluations of

f

. We assume that the function

f

is defined on an

\ell_2

-ball in

\Real^d

,

g

is twice contin ...

Stochastic Optimization of Sailing Trajectories in an America's Cup Race

Frédéric Dumas

The main objective of the thesis is the study and the determination of an optimal navigation strategy, for a sailboat in an America's Cup race, by methods of stochastic optimization. Such methods are appropriate because the sailing team expects the wind to ...

Simulation of atmospheric flows over complex terrain for wind power potential assessment

When assessing the economic viability of a wind farm, the estimation of the on-site wind power potential is perhaps the most important step. The most common way of evaluating the wind power potential of an area of interest consists of making on-site measur ...
