Overview
IEC TS 61968-2:2011 is the glossary part of the IEC 61968 series, titled Application integration at electric utilities – System interfaces for distribution management – Part 2: Glossary. This technical specification defines and explains the terms and abbreviations used throughout the IEC 61968 series. As a companion to the interface definitions in the other parts, it ensures consistent vocabulary for distribution management systems (DMS) and related utility IT integration efforts. The second edition adds many new terms (notably to support IEC 61968-9) and updates earlier definitions, making it a core reference for Smart Grid interoperability and system integration.
Key Topics and Requirements
- Terminology for DMS and ICT: Clear definitions for distribution management, information and communication technology (ICT) concepts, and cross-domain terms used across the series.
- Abstract and application components: Definitions that underpin the IEC 61968 interface reference model (e.g., abstract component, application component, adapter).
- Metering and AMI vocabulary: Standardized terms for metering systems (advanced meters, automated meter reading, advanced metering infrastructure, advanced meter management).
- Measurement and power terms: Common electrical terms such as active power, apparent power, energy units, and accuracy-related vocabulary.
- Abbreviations list and bibliography: A consolidated glossary of abbreviations used in IEC 61968 and references to authoritative sources (e.g., Electropedia, IEC 60050).
- Cross-references and notes: Usage guidance, cross-references between related terms, and citations that support consistent interpretation across all IEC 61968 parts.
Applications
IEC TS 61968-2 is a practical reference to:
- Promote consistent terminology when designing and documenting system interfaces for DMS.
- Support inter-application integration efforts where heterogeneous legacy and new systems must exchange data via middleware and message brokering.
- Aid the development of interface specifications, mapping documents, API contracts, and message schemas used in Smart Grid and utility IT projects.
- Reduce ambiguity in procurement documents, technical requirements, and vendor communications by using standardized definitions.
Who Uses This Standard
- Utility IT architects and engineers designing DMS integrations
- System integrators and middleware vendors
- Metering and AMI solution providers
- Consultants, regulators, and standards committees working on Smart Grid interoperability
- Software developers and testing teams implementing IEC 61968-compliant interfaces
Related Standards
- Other parts of the IEC 61968 series (interface definitions and mappings)
- IEC 61968-9 (specific expansion supported by the 2nd edition glossary)
- IEC Electropedia and IEC 60050 for broader electrotechnical vocabulary
By centralizing definitions, IEC TS 61968-2 improves clarity, supports interoperability, and accelerates Smart Grid and DMS integration projects through consistent, authoritative terminology.
