"The D8.2 utilizes a hydrodynamic torque converter developed by Voith AG with a synchronous A.C. generator, effectively a variable speed transmission, that is able to connect directly to the grid at high voltage. No complicated power conversion electronics are required, the company claims."
For large amounts of power, a mechanical method such as employed by the D8.2 may work well but it seems to me that the sensitivity of the response will be based upon the ability of the variable speed transmission to adjust rapidly to changes. In other words, the time delay may be greater than for power conversion electronics but for 60 Hz, it may be sufficient.
Ideally, I would think that there may be a method to hybridze the two by using the power conversion electronics to fill in the gap for the transmission adjustment but again, I am not an electronics nor a mechanical expert. I think that what is required is some type of pressure or force sensor unit providing and compensating for the constantly changing wind energy that is being generated by fluctuating wind velocities.
The question here is whether or not some type of computer program could be generated to match wind energy production and, if this could be done, could this program be used to provide for rapid mechanical adjustment.
There must be some mathematical algorithms that could be worked out to accompany energy production during wind changes. Is the source of the wind storm generated, generated from changes in high/low pressure areas, from seasonal effects or other inputable data? Then the magnitude and velocity range of the gusts and other factors might be worked out along with time period constraints. In other words, I am sure that, with a definable input, a good mathematical pattern could be worked out.

"Thanks for the nice piece on AEP in today's publication. You explained it correctly... really got it right. In my experience, that's all too rare among even the most professional of journalists!"

Perhaps some mathematician has already done this.
