Description
Describe the current behavior
If a nominal voltage is NaN in the json crac, the margins in A are infinite. This causes issues if trying to export margins in A or optimizing in A.
Describe the expected behavior
If the nominal voltage is not present in the crac file, we can use the network nominal voltage to convert from MW to A.
Describe the steps
- Create a crac with a cnec that has a MW threshold and NaN nominal voltage
- Optimize in A or try to export A margins
