Synchronization is a one time event. Once the networks are coupled the physics itself keeps it in sync. The problem is that physics also dictates that the interconnection links need to be big enough to handle the power imbalance between the different parts of the networks. So grid management is mostly about balancing production and demand as a whole and in sub-grids.
