This proposed concept makes absolutely no sense to me. Alternating current
isn't the
same as battery charging, which is sorta what is implied by "leading the
phase" and "pumping power into".
Leading the phase by 5%, for example, also means that it's lagging by 95%.
Differences in potential that will be present, will have the effect of
loads.

The way more power is available is that the output current capacity of the
"grid" is increased by adding more parallel precisely-in-phase current
sources.
I would think that it's highly likely that special equipment is used to
synchronize the phase and frequency of a generator's output before the
contacts close.

A mismatch in phase or frequency should be avoided, not intentionally
induced. Mismatches will cause dramatic currents due to differences in
potentials.

The out-of-phase reaction can be observed when parallel connecting the
secondary windings of a dual-secondary power transformer. The out-of-phase
current is maximum opposed currents.
This test is best done with a test lamp to avoid destruction of the
transformer.

When the dual secondary windings are properly phased, the current capacity
essentially doubles.
For a transformer with dual 12V 5A secondaries, the output current capacity
would be 10A.
This same practice is followed when connecting secondary windings of
separate transformers.

One would not attempt to parallel the output terminals of an individual
3-phase transformer for the same reasons. The out-of-phase currents would
cause instant destruction of the transformer.

There isn't any practical reason to try to determine which phase leads, it's
not relevent and has no meaning in AC power usage. In your home L1 and L2
are opposed, and that's not an indicator of which one occurs first in real
time.
The same with 3-phase, it's just the separation of the phases that gives it
it's characteristics.

In working with either one in home or shop environments, load balancing is
about the only important consideration, with safety being at the top of the
list.

The phase of the frequency determines where the power goes on the grid.
Lead the grid and you pump power into the grid while matching the grid
phase
and you won't pump anything into it. A really neat trick.

The highly accurate frequency requiement is not for timing, it is to
allow the national electical grid (acutally the east and west coast
grids) to function. When you have hundreds (thousands?) of multi
megaawatt generators all essentially hooked up parallel, you have to
have the frequency variation set as small as technically possible. If
not, you get some massive eddy currents in the system.
