Shell model for loads

ObjectStab.Loads.Partials.Load

Information

The complex power a load draws from the network is given by:

S = P+jQ = v * conj(i)

The parameters P0 and Q0 denote the rated load power, i.e., the power
the load draws if the voltage is 1 p.u.

Parameters

NameDefaultDescription
P01Rated Load Active Power (at 1 p.u. voltage) [p.u.]
Q00.2Rated Load Reactive Power [p.u.]

Modelica definition

partial model Load "Shell model for loads" 
  extends Base.OnePin;
  
  parameter Base.ActivePower P0=1 
    "Rated Load Active Power (at 1 p.u. voltage)";
  parameter Base.ReactivePower Q0=0.2 "Rated Load Reactive Power";
  Base.ActivePower Pl(start=P0) "Active Load Power";
  Base.ReactivePower Ql(start=P0) "Reactive Load Power";
  
equation 
  T.ia = (T.vb*Ql + Pl + Pl*T.va)/(1 + 2*T.va + T.va*T.va + T.vb*T.vb);
  T.ib = (Pl*T.vb - Ql - T.va*Ql)/(1 + 2*T.va + T.va*T.va + T.vb*T.vb);
end Load;
