Comparison with the other Architectures ndash For each wind
The second reason for the selection is that, since the proposed support method is based on the SOP approach of , using the similar system will allow for comparative evaluation of the results.

The link between the operating point and the shaping parameters is established through the Voreloxin function. The number of shaping parameters is based on the operating point, e.g., for wind speed below rated wind speed, all six shaping parameters (a1, a2, ta1, ta2, dx1, dx2) are to be optimized.
(i.e., D = 6) whereas, for the other operating points, only three shaping parameters (a1, ta1, dx1) are sufficient (i.e. D = 3), since the deceleration period is not required for high wind speeds.
To take advantage of the variable nature of the SKE, the shaping parameters are optimized for ten different operating points which cover the entire operating region of the WT. For each operating point, ten optimization replications were carried out and the optimization was terminated upon reaching a predefined value of maximum number of function evaluations (Max FEs). For each run, Max FEs was set to 5000 × D as per CEC′08 guidelines .
