Maximum power
(OP)
At what angle difference when Synchronizing a generator to the grid is the power (watts) the greatest?

I would tell you more of what I don't know but the post would be way too long. Thanks for the help.

RE: Maximum power
It is not an objective to maximize power or current at the time of synchronization. Typically we try to match angles closely, erring slightly on the side of generator angle lagging supply angle to avoid reverse powering the generator.

RE: Maximum power
Following what David and Electripete said you normally synchronize at close to 0 phase angle. This minimizes disturbance to the system and impact on the machine, and results in little power flow right away. Once on-line, then the throttle is advanced to load the generator. As you add more power, you will eventually reach the maximum prime mover capacity or maximum power angle, whichever comes first.

RE: Maximum power
I think you are mixing up the phase angle difference during synchronization and the power angle at which maximum power transfer takes place. They are two different things.
The intent and attempt at the time of synchronizing is to keep the phase angle difference between the grid and generator as well as the power exchange between the two as close to zero as possible. Out of phase synchronization can lead to to heavy short circuit currents, avoiding which would be your prime objective.
The maximum power angle at which maximum power transfer would take place between the source and a load is the function of the system characteristics, which is something different and would be of concern only after the generators are on line.
