NERC - Supports IEC 61850 to keep the Transmission and Distribution Grid reliable

NERC (North American Reliability Corporation) has just published an interesting comprehensive analysis of the impact of Smart Grids on the reliability of the transmission grids:

Reliability Considerations from Integration of Smart Grid
December 2010

The report recommends that the interoperability of devices and systems is one of the crucial issues in future electric power systems - including industrial sites and buildings. There is obviously one standard that supports the interoperability to a high extend on all voltage levels: IEC 61850.

On page 82 the report states: "An important example of why smart grid standards need to recognize the interoperability between equipments used in transmission and distribution, is the requirement of mapping of Distributed Network Protocol 3 (DNP3) with IEC 61850. DNP3 is the legacy communication protocol that is followed for large volume data exchanges between equipment. However, IEC 61850 is recognized to be a better standard suited for smart grid communications. To bridge the gap between the legacy DNP3 protocols and the newer IEC 61850, a mapping is required when exchanging certain data types. The goal is to ensure that data are seamlessly transported between devices regardless of their adopted communication standards. DNP3 has recently been adopted in IEEE Standard 1815. An IEEE standard and an SGIP PAP working group are currently supporting the mapping effort between IEC 61850 and the IEEE 1815/DNP3 standards."
