.PowerGrids.Electrical.Buses.EquivalentGrid .PowerGrids.Electrical.Buses.EquivalentGridThis model describes an equivalent grid with an internal impedance driven by a constant voltage source.
The impedance is computed to provide a power flow SSC/c out of the voltage source, assuming the voltage is set to the nominal value UNom and that the grid terminal is shorted to ground.
The actual modulus and phase of the voltage source are computed to give the required voltage modulus and phase URef, UPhaseRef during initialization.
