this has been discussed, and the problem with using MPPT on wind is
that the response of a wind turbine is very different from a PV. It
has inertia. There is some potential value in using buck and boost
techniques to alter the operating voltage, but the best tactic is to
use a pre-programmed power/speed curve rather than to 'seek' the best
power.
