When the power angle of one generator is increased and the load remains constant, do the power outputs of the other generator automatically decrease, i.e. does the power angle of the other generator automatically decrease? Is this droop control?
Yes, you got it! HOWEVER not 100% The frequency will slightly deviate but there will be no acceleration as it would without the droop. The deviation will be compensated by a central system controller. If the droop would compensate 100% there would be oscillations in the power system.
For synchronous generator, the speed is exactly the same as the grid frequency (except if the generator looses sync. due to a too high phase rotor angle). For an asynchronous generator/motor it is fundamentally different. If power is to be generated there needs to be a difference between rotation speed and grid frequency, this difference is called slip. A sync. gen. has no slip.
Awesome video! Thank you!

Isn't this called SLIP in an induction generator?
