Abstract
Wind turbines usually operate in an unsteady flow environment. Therefore, the blade element forces vary with time and position of the blade and are influenced by the ambient turbulence, the blade vibratory motions, the control inputs, and the skewed flow. Thus, many methods of operation control are implemented in the new design of horizontal axis wind turbines such as the pitch control, the pitch power control, the passive stall power control, and the active power control (Burton et al. 2001).
