Could not set nominal voltage for bus sourcebus - Opendss to glm conversion

[Barsha96]

Hi, I am using Ditto to convert from OpenDSS-G to Gridlab-D. I am facing a lot of issues doing that. I am not sure if there is any information I am missing.

Details:
When I convert OpenDSS-G's master file to glm using the following command:
ditto-cli convert --from opendss --input "C:\Users\bupadhy\OneDrive - UTol\Desktop\conversion\CampusModel\ModelDSS\Master.dss" --to gridlabd --output ./CampusModel/converted

I get two errors:

Log file currently not supported, please contact the developers for information on how to generate log files
Could not set nominal voltage for bus sourcebus

But I can see a converted glm files. However, for whichever OpenDss model I convert, It gives out the same Model.glm.

Model.glm:

module powerflow{
    solver_method NR;
    NR_iteration_limit 50;
};

object node {
    name nnode1;
    phases ABCN;
     nominal_voltage 2400.0;
};

object node {
    name nnode2;
    phases ABCN;
     nominal_voltage 2400.0;
};

object node {
    name nnode3;
    phases ABCN;
     nominal_voltage 2400.0;
};

object node {
    name nload4;
    phases ABCN;
     nominal_voltage 2400.0;
};

object load {
    name nload_load_load4;

object overhead_line{
    length 2000.000064;
    configuration line_config_1;
    name nnode1-node2;
    from nnode1;
    to nnode2;
    phases ABC;
};

object overhead_line{

    configuration line_config_1;
    name noverhead_line:34;
    from nnode3;
    to nload4;
    phases ABC;
};

Are there any preliminaries to be understood before converting OpenDSS-G's Master file to a Gridlab-d Model? I have attached the OpenDSS-G model I am working with and the glm file converted by ditto. I would appreciate any help in this.

@Barsha96 The .dss files are broken:

• This doesn't work (.3_1): New "Line.sw33" phases=3 bus1=b31.1.2.3 bus2=b31n1.1.2.3_1 Switch=True
• Capacitors are using kV=0:

New "Capacitor.c1" phases=3 conn=wye kv=0 bus1=b7n2.1.2.3 bus2=b7n4.1.2.3
New "Capacitor.cap_1" phases=3 conn=wye kv=0 Numsteps=3 bus1=b7n6.1.2.3 bus2=b7n7.1.2.3

Still, I tested DiTTo with OpenDSSDirect.py v0.6.1 and the latest v0.7 and both reported errors.
Before OpenDSSDirect.py v0.7, GIScoords command should also fail, per #387.

I recommend trying to run in official OpenDSS directly since it will also report various errors there.

(@kdheepak Hope you don't mind me checking this, just making sure everything is fine on ODD.py)

Thank you for your direction. I'll try and look for the errors in the dss model.
Something I wanted to figure out, I tried converting IEEE_4_node.glm file to the dss format as I wanted to try with a working dss file, converted it back again to glm format. The conversion gave me the same file as the other models did and with the same error. I am searching for a good example dss files as well which will convert correctly to the glm. Anywhere I can get those?

So far, I only have the dss models that are giving me the same exact file with the same content and the same error. If I get some other working dss file to convert, I might get more answers as well.
