Only psse substations with a single voltageLevel are supported.

All psse substations are supported.
A psse substation is considered valid if:

• All the nodes connected by switches (regardless of the switch status) are associated with a single psse bus.
• Equipment is associated with the correct psse bus.
• Bus and node control are coherent.

A voltageLevel is defined as nodeBreaker if all psse buses are within the same psse substation.
The IIDM substation id has been extended to include all the psse buses within it. (Sbus1_bus2_..._busN)
