Elastic electricity prices in the IMPEXP region

Tough question.

You can of course prevent both export and import occurring in the same time slice, by exogenously assuming for each timeslice, that only export/import can occur in that timeslice. But if you want the model to decide by itself the sign of the net imports in each timeslice, I cannot see how you can prevent the model from exporting and importing in the same time, if that happens to be profitable. If you find a way, I'd be interested to learn how.
