Overview
IEC TR 61850-80-3:2015 is a Technical Report in the IEC 61850 family that specifies requirements and technical choices for mapping IEC 61850 services to web protocols. It defines a two‑step approach: collection of Smart Grid use cases and requirements, and evaluation/selection of technologies to create a consistent SCSM (Substation Communication Service Mapping) based on web protocols. The report surveys candidate technologies (notably XMPP) and describes how IEC 61850 ACSI services and MMS/XER payloads can be transported over web protocol stacks while addressing performance, interoperability and cybersecurity.
Key Topics
- Scope & Requirements: Detailed requirements including transfer time, throughput, data integrity, reliability, availability, interoperability, cybersecurity, device size, scalability and ease of implementation.
- Use-case driven analysis: Use cases covering PV inverters, wind, hydro/thermal, CHP, smart customer/DR, e‑mobility, VPPs, microgrids and feeder automation guide design choices.
- Technology assessment: Evaluation and selection of web technologies suitable for a new SCSM; XMPP is presented as a primary candidate with architecture, addressing, federation and presence monitoring explained.
- Message mapping: Definition of XML payloads (XER encoding of MMS/ACSI) and rules for transporting solicited and unsolicited IEC 61850 services over XMPP.
- Security: Consideration of TLS, SASL and end‑to‑end security mechanisms for web protocol transport and device trust models.
- Interoperability & synergy: Guidance on coexistence and synergy with existing mappings (e.g., IEC 61850‑8‑1) and gateway approaches for dual‑stack environments.
- Annex material: Examples and payload samples (MMS XER), architecture figures and domain‑specific requirements.
Applications
- Utility system architects and engineers designing Smart Grid communications that require web‑protocol transport for IEC 61850 services.
- Device and software vendors implementing IEC 61850 SCSM over web stacks (XMPP clients/servers, XML/XER encoders).
- Integrators creating gateways between legacy MMS/BER mappings and web‑based SCSM implementations.
- Cybersecurity teams assessing TLS/SASL and end‑to‑end security for IEC 61850 messages transported via web protocols.
- Project managers and standardization stakeholders evaluating technology choices to reduce time‑to‑market and improve interoperability across distributed DER, VPP and customer domains.
Related Standards
- IEC 61850 (family): foundational standard for communication networks and systems for power utility automation.
- IEC 61850‑8‑1 / 8‑2: existing SCSM mappings referenced for synergy and gateway design.
- IETF protocols and specs related to XMPP, TLS and SASL (as used for authentication and transport).
