CGMES export has inf attr for r,x for tie lines

AnkurArohi opened this issue · comments

Describe the current behavior

Exported CGMES has inf values for the tie lines although the corresponding dangling lines have zero values for these attributes.

Describe the expected behavior

The tie lines should recieve the sum of the r,x values from the dangling lines, if this leads to issuesin the load flow calculation since they are zero one could add a small value of impedance and make it parameterable.

Describe the steps

  • import network_tso,(with all the BD files)
  • import network_dso(with all BD files)
  • Merge the networks
  • Export the network in CGMES format
  • Look for r,x values in the exported CGMES for these tie lines
