Large Eddy Simulations of the flow past an array of three aligned turbines have been
performed using two different control strategies: constant torque gain and the Extremum …

The extremum seeking control (ESC) algorithm has been proposed to determine operating
parameters that maximize power production below rated wind speeds (region II). This is …

This paper proposes a nested-loop extremum seeking control (NLESC) scheme for
optimizing the energy capture of wind farm that is formed by a wind turbine array along the …

Aerodynamic interaction among turbines grouped together in wind farms causes a decrease
in the total energy extracted from the wind when compared to an equal number of widely …

When a wind turbine operates between the cut-in and rated wind speeds, the machine is
controlled to maximize wind energy capture. The extremum seeking control (ESC) algorithm …

Abstract Extremum Seeking Control (ESC) is a model-free control strategy that uses a dither
signal to enable a gradient search to find an optimal operating point. The adaptability and …

Power optimization and control for grid-coupled wind energy conversion systems (WECS)
has been extensively studied for variable speed wind turbines. However, existing methods …
