Model of a PQ load with voltage dependence.
port.P = PRef*(port.U/URef)^alpha;
port.Q = QRef*(port.U/URef)^beta.
By default PRef = PRefConstQRef = QRefConst,
so by just setting the PRefConst and QRefConst parameters one can obtain a PQ source with fixed reference P and Q values.
It is possible to change the binding of PRef and QRef when instantiating the model, to obtain time-varying PQ loads without the need of signal generator blocks, e.g.
LoadPQVoltageDependence myLoad(PRef = 1e8 + (if time < 10 then 0 else 1e7));
PRef and QRef.
By default alpha = beta = 0 so there is no voltage dependence.
