contingencies after changing switching states

If lines and transformers are switched off during optimization, it is possible that contingencies from case.con can no longer occur, because the affected asset is already switched off.

How is this to be handled?

Should the results of these contingencies be equal to those of the base case in these cases?

Thanks

In the case of a contingency K defined by the outage of a grid element J that was already disconnected in the base case, all of the general rules apply:

  • A contingency K solution file needs to be written.
  • Element J should not be included in the contingency K solution file.
  • The constraints on the contingency K solution are those listed in the formulation. In particular, the contingency K solution need not be the same as the base case solution.
