The positive sequence voltage source is an ideal voltage source behind an internal series impedance. The parameter values for V, Rs, and Xs are in p.u.

p.u. (network base)
Note: When dynamic simulation is set to Start from Power-flow in Simulation settings tab of the Solver, the voltage magnitude and angle of the internal ideal voltage source is recalculated to match with the power-flow results of the connected bus.
For the power-flow computations, the connected bus should be defined as a SLACK and the set-point voltage and magnitude of the bus is taken from the bus page (for Excel) or bus data record (for PSS/e).
