Run-time error about andes HOT 11 CLOSED

from andes.

I was able to replicate the issue with kundur_vsc.xlsx. Working on a fix now.

from andes.

It has been fixed in the latest develop branch in f8af14c.

from andes.

Also, the kundur_vsc.xlsx test case has been updated.

from andes.

I still report the following error:

Thank you!!
I solved the problem.
Than , when i run the command : ss.TDS.run()
I got the following problem:

I'm using jupyter lab ; python version is 3.9

Thank you,
I need to clone the code under develop branch, right?
