(301) OpenDSS: You must create a new object first:

[Vishal Verma]

Dear all,
I was trying to interface OpenDSS with MATLAB. I see that many users faced same error message. I tried to do what others have suggested like using '.' between new and circuit name, and making sure that file is saved in ANSI.
Please help me with what I'm doing wrong, here's my code.
clc;
clear all;
close all;
DSSObj=actxserver('OpenDSSEngine.DSS');
if ~DSSObj.Start(0),
disp('Unable to start the OpenDSS Engine');
return
end
DSSText=DSSObj.Text;
DSSCircuit=DSSObj.ActiveCircuit;
%%Above command is to interface MATLAB with OPENDSS
DSSText.Command='Compile(C:\Users\Pathh\IEEE13Nodeckt.DSS)';
DSSText.Command='Set mode=snap';
DSSText.Command='solve'; % to solve
%DSSText.Command='Show Losses';
%DSSText.Command='Show Power';
%DSSText.Command='Show voltages';
And then I copied pasted IEEE13Nodeckt file( I did this because I thought that file I wrote might have some problem):
Clear
Set DefaultBaseFrequency=60

!

new circuit.IEEE13Nodeckt
~ basekv=115 pu=1.0001 phases=3 bus1=SourceBus
~ Angle=30 ! advance angle 30 deg so result agree with published angle
~ MVAsc3=20000 MVASC1=21000 ! stiffen the source to approximate inf source
%%%%%% and continued

Before that my file was:
clear

new circuit.IEEE_4 phase=3 BASEkV=11 bus1=SourceBus MVASC1=5000000 MVASC3=5000000
! Define the circuit elements
Redirect Lines.DSS
! Rediercted lines file to Master file
Redirect loads.DSS

! Let the openDSS estimate the voltage bases

solve maxcontrol=100
Set Voltagebases=[11]

set controlmode=static

Hi,

Have you tried one of these:

Best regards

Thanks Davis, one of the example worked 'MiscExample.m'. Let me work on why others are showing error. Thanks.
