Scenario 4 is concerned with high wind speed, low turbulence
intensity and low electricity demand. As electricity is demand low,
w1is set as 0.1,w2, w3 and w4 are set as 0.25, w5is set as 0.15 (see
Table 3). In this case, the optimized power output is lower but much
smoother than the original one. Due to low electricity demand, the
increase of generation is diminished to improve the power quality.
In the same way, rotor speed, generator torque and blade pitch
angle are smoothed after optimization. Figs. 7–10 show the results
of optimization of the power output, rotor speed, generator torque,
and pitch angle.
