Get Load.KW settings via COM inteface

[Iromi Ranaweera]

How can I get the kW settings of all the loads in a network? I am running time-based simulation loop with matlab. I thought following code would work. However, with this code, I get the same value for kW setting for a load at certain bus. It does not change with the time. What is the wrong with this code? Is there any other way to do this?

for t=1:time_duration
    DSSSolution.Solve; 
    for i=1:number_of_Loads       
        Load_name=['LOAD' num2str(Load_nodes(i))];
        DSSCircuit.Loads.Name=Load_name;
        P_load(t,i)=DSSCircuit.Loads.kW;        
    end
end

Thanks!

Hi,

I've modified your code to make it work:

DSSElement  =   DSSCircuit.ActiveCktElement;
for t=1:time_duration
    DSSSolution.Solve; 
    for i   =   1:number_of_Loads       
        Load_name   =   ['LOAD' num2str(Load_nodes(i))];
        DSSCircuit.Loads.Name   =   Load_name;
        powers                  =   DSSElement.powers;
        P_load(t,i)=powers(1);  % (1) kW, (2) kvar         
    end
end

Best regards

Thanks for the help. Now it is working.

for load in myloads:
KW=DSSCircuit.SetActiveElement('load.Kw'+load)
print("loadname is:", load)
print("load kw is :", KW)

IS this correct way to access each load kW in loop, since getting an error where each load KW shown is -1?
