The purpose of this model is to support the development of Grid-Forming Inverter models as described in [Du2021]. The model provides a voltage source with an internal voltage source and internal impedance whose magnitude and angle can be varied via inputs starting from their initial values.
See the documentation of BaseClasses.baseVoltageSource for more information.

| useEphasorInternalAsInput | If true, the values of E0 and delta0 are computed internally and used as the start value of the input, requiring only a deviation \Delta E and \Delta delta to be supplied. If false, the magnitude E and angle delta must be supplied, including the correct value of E0 and delta0 needed for proper initialization. |
