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.<\/p>\n
\nNOTE 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.<\/p>\n<\/blockquote>\n
The structure of this part of IEC 61850 illustrates a two-step approach:<\/p>\n
\n
- \n
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:<\/p>\n
\n
- \n
PV-inverters<\/p>\n<\/li>\n
- \n
Hydro and thermal generation<\/p>\n<\/li>\n
- \n
Wind power plants<\/p>\n<\/li>\n
- \n
Combined Heat and Power (CHP)<\/p>\n<\/li>\n
- \n
Smart customers<\/p>\n<\/li>\n
- \n
E-Mobility<\/p>\n<\/li>\n
- \n
Virtual Power Plants (VPP) and micro grids<\/p>\n<\/li>\n
- \n
Feeder automation<\/p>\n<\/li>\n<\/ul>\n<\/li>\n
- \n
Evaluation and selection of technologies in order to build a consistent SCSM. Clause 7 presents the future SCSM 8-2, including an overview of the main selected technology: XMPP. The following goals have been particularly considered for the definition of this SCSM:<\/p>\n
\n
- \n
Identify a single profile supporting all the services required by the domains and defined today in ACSI.<\/p>\n<\/li>\n
- \n
Cover the full life cycle of a IEC 61850 system, in collaboration with the System Management work in WG10 (from configuration, through conformance testing, down to maintenance). For this purpose, this part of IEC 61850 may recommend some changes to other parts of the IEC 61850 series such as Parts 6 and 10, etc.<\/p>\n<\/li>\n
- \n
Deploy cyber-security to ensure a secure environment (in compliance with the IEC 62351 series).<\/p>\n<\/li>\n
- \n
Propose rules for cohabitation with other mappings such as IEC 61850-8-1 and IEC 61850-9-2, and possibly recommend communication profiles depending on specific application context (pole-top equipment, inside DER, connection of DER, etc.).<\/p>\n<\/li>\n
- \n
Only the A-Profile is addressed here. Nevertheless, support of TCP\/IP and UDP\/IP is required for the T-Profiles.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
What is not included in the study:<\/p>\n
\n
- \n
Modification of objects specified in IEC 61850-7-3 and IEC 61850-7-4<\/p>\n<\/li>\n
- \n
Introduction of several competing web protocols profiles<\/p>\n<\/li>\n<\/ul>\n
