In pandapower it is possible to set a line parameter “in_service” to false and the model will still run with all connected loads set to zero. I tried to set “br_status” to 0 in powermodels but then the model returns infeasible. Is there a shortcut to simulate a line outage in powermodels?
You are correct that setting br_status to 0 is the right way to remove a branch from the model. It does not automatically set all connected loads to zero. To do that try running the simplify_network! or deactivate_isolated_components! on the data after the branch is removed.
Thank you for the tip (and sorry for the late reply), I will check out those functions.
