check_thermal_limits on multiconductor networks

[pseudocubic]

Discuss best implementation of check_thermal_limits for multiconductor networks, particularly with inactive conductors on a line.

[ccoffrin]

The current implementation does not have the correct semantics for multiple phases. The simplest solution for now is to add a check that the incoming date is implicit single phase. A good generalization will require some thought.

[ccoffrin]

Will this be resolved by the changes PowerModels v0.15?

[pseudocubic]

It looks like we are using correct_thermal_limits! in PMD without problem, but I don't know if calc_thermal_limits is working, I will do some tests. Note that there is a dangling reference to MultiConductorVector (commented out) in calc_thermal_limits

[ccoffrin]

Closing as PMD no longer depends on PM.
