How to change voltage angle in dynamic simulation

Consider SLD with single machine infinite bus, changing magnitude of the voltage in dynamic simulation can be done by changing Vref of Infinity machine. Or, it can be done by changing transformer tap. Question is: How to make voltage angle change ? (for example change 20° in step)

Thanks,

I don't understand. In a dynamic simulation the voltage angle is a result at each time step and not input data that can be changed by the user.

I want to test generator behavior if there is voltage angle changes in the grid.

Change the phase shift of the generator step-up transformer with 20 degrees. For example use API:

psspy.two_winding_chng_4(3008,3018,r"""1""",[],[_f,_f,_f,_f,_f, 20.0])

to change for generator at bus 3018 in savnw.sav.
