IEC 61850 and DC

IEEE invites all interested parties to contribute to the development of a plan "DC in the Home" to ensure that DC electricity can be safely and conveniently accessed in homes, eliminating the wasteful conversion of AC to DC, and in many cases, DC to AC, prior to entering the home.

This seems to be an interesting question. I guess people digging into this issue will – some time down the street – start discussing a DC communication standard. Is this required? I guess it is not needed.

IEC 61850 could already be applied as well for DC systems. IEC 61850 defines many models for, e.g., PV inverter, batteries, storage systems, DC protection, … DC measurements.

As an example see the logical node MMDC defined in IEC 61850-7-4 Ed2:
