Reduce Network is not working #736

Open vlgmarchesini opened 2 months ago

vlgmarchesini commented 2 months ago

Describe the current behavior

When I call the function network.reduce, it pops out an error: 'PyPowsyblError: Parent tie line WTREBI5 XTR_HN51 1 + XTR_HN51 0HNOVI51 1 should be removed before the child dangling line'

Regardless of filtering by ids, voltage levels, and setting 'with_dangling_lines' to True or False, the error persists.

I tested with several different Common Grid Model uct files and the same error appears. Once I remove all tielines that are not in the interest area. It works...

Describe the expected behavior

I would expect to reduce the problem size (interest area) an decrease time to run load flow and security analysis.
