No, just simplistic. A DC motor connected to a second DC motor, of the permanent magnet type, will allow you to turn one shaft and see the other shaft rotate. The one that has mechanical power input, acts as a generator; the one that has electrical power input, acts as a motor.
But the two ends are the same thing.
To a lesser extent, in a short interval spike, all the rotating machinery on a single AC line acts as a flywheel-load or flywheel-generator (depending on the sign of the spike).
Wind turbines, though, aren't generating directly into the grid, but into conversion electronics ( they have to match grid frequency despite the operating rotary speeds that vary with the wind). One wouldn't expect reversibility of that conversion.
