How do you phase lock the French grid to the Belgian Grid to the Dutch

Are they phased locked? I don't know.

Most of Europe is phase locked.

There is an interesting situation also in that Germany's neighbours are
actually being forced to balance the N-S parts of Germany's grid because
Germany itself has loads of solar power in the south and wind power in
the north and there are significant power flows between N and S in
excess of what the German grid alone can handle.

The cost of handling the excess is borne by e.g. Czech republic which
has made serious noises about disconnecting itself from Germany as the
whole power flow is destabilising its own grid.
