Pretty much the same as any generation source.

You bring everything up off the grid, synchronize to the grid, and then
"throw the switch" putting your generation on the grid.

The generator will then remain synchronized to the grid, acting as a
generator when you put more water through it, acting as a motor when you
don't put enough water through it.

Kinda simplistic description, but the reality is fundamentally just
that.

There is no conversion to DC and back or anything like that. Only cases
where that is true is either Solar (where the generation is DC) or some
(most?) wind generation.
