So the source is a constant and the regulator rectifier meters the current, it maintains it at a constant 14.4vdc.
Some older small bikes had a 6 volt system, these mostly have a 12 volt system. The amount of AC current coming off the stator would fry the battery and burn all the light out if it was not buffered. The electrical systems are 12 to 15 Vdc.
The variance is discharged same as based load energy if not used it gets discharged, in the power plants they have beyond base load that comes on in peak demand usually NG powered, to the best of my knowledge I do not believe that any power grid stores electricity, the required banks of batteries would not be economical or cost effective. There are batteries on the grid but they are not part of the grid they are consumers on the grid, in the event the grid goes down as in battery back ups. They protect critical systems and are typically configured with secondary generators and are not part of supply grid they are private or secondary on the grid.
Most people have trouble with that concept, that the substation are discharging excess generation, its normal operation.
What matters more to you on an 18+...
