Communication networks and systems for power utility automation – Part 80-3: Mapping to web protocols - Requirements and technical choices - Edition 1.0
 N TR 61850-80-3

Annotation

This part of IEC 61850, which is a technical report, describes the requirements and gives an overview of the technical solution for using Web Protocols as a new communication mapping (SCSM) for the IEC 61850 standard.

NOTE The notion of Web Protocols covers here the Web Services technologies, extended by other well deployed technologies based on standards used in the IT domain (IETF, ISO, W3C, OASIS, etc.). The advantage is that due to a lot of professional knowledge and practical experiences in the IT world the risk of non-interoperable solutions in the smart grid domain will decrease.

The structure of this part of IEC 61850 illustrates a two-step approach:

• Collection of the use cases and requirements based upon emerging Smart Grid architectural considerations, taking into account the new extended scope of IEC 61850. Clause 6 proposes a synthesis of the global requirements, while the use cases of the various domains are described in Annex A.

The considered domains are:

– PV-inverters

– Hydro and thermal generation

– Wind power plants

– Combined Heat and Power (CHP)

– Smart customers

– E-Mobility – Virtual Power Plants (VPP) and micro grids

– Feeder automation
