Simple- Put a flywheel battery - charged by windmill and discharged by you.

The battery trickle chargers are available that will accept variable voltage, may be with a bit boosting.

You will need a DC-DC converter that can operate in "Boost" and "Buck" modes, meaning it will always provide the same DC voltage out, when the input is below or above the set output voltage. I would think there would be these types of modules available at the same places that provide windmill generators or solar systems.

Good luck with your project
