modelLoadPQVoltageDependenceInputs
Load model with voltage dependent P and Q specified by inputs
Extends from LoadPQVoltageDependence (Load model with voltage dependent P and Q).
Information
Model of a PQ load with voltage dependence.
port.P = PRefIn*(port.U/URef)^alpha; port.Q = QRefIn*(port.U/URef)^beta;
The reference active and reactive powers are provided by input connectors.
By default alpha = 0 and beta = 0, so there is no voltage dependence.
