scope:

The usage of the IEC 61850 communication standard is largely spreading over all the domains connected to the smart grid, pushing the usage of technologies adapted to the connection of a very large number of applications and devices across the intra/inter-net (see related use cases in Annex A). The involved domains use already well established protocols typically for exchanging data with IT level applications like resource planning, asset and maintenance management, etc. Therefore, it becomes imperative to provide an integration strategy that allows the integration of IEC 61850 into these various disparate protocols and information. In this context, Web Protocols are considered as the more appropriate technology for communication with backend systems and possibly field devices (see new work item proposal 57/1181/NP). Following this NWIP, the present document 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 mentioned initially in the NWIP, extended by other well deployed technologies based on standards used in the IT domain (IETF, ISO, W3C, OASIS ...). 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.
