Full title and description

Energy management system application program interface (EMS-API) - Part 600-1: Common Grid Model Exchange Standard (CGMES) - Structure and rules. This international standard specifies the structure, rules and constraints for exchanging assembled and merged power system models using the CGMES approach and defines how relevant Common Information Model (CIM) standards work together to enable interoperable model exchange.

Abstract

The document defines CGMES structure and governance including profiles, serialization formats, profile constraints, and rules for model authority and merging (Model Authority Sets). It is intended to support interoperable exchange, validation and merging of power system models between model authorities, transmission system operators, distribution network operators and software vendors without prescribing business processes or application implementations.

• Edition / version: Edition 1.0 (2021-06).
• Number of pages: IEC PDF: 47 pages (some national/adopted EN versions record 49 pages due to front/back matter).

Scope

Defines the structural rules, mandatory requirements and profile definitions that constitute the Common Grid Model Exchange Standard (CGMES). The standard establishes how CIM building blocks are combined, extended and constrained to form CGMES profiles, specifies serialization and validation requirements for exchanging assembled and merged models, and prescribes governance elements such as identification of Model Authority Sets (MAS) to support multi‑source model assembly and conflict resolution. It does not define business processes or application internal implementations.

Key topics and requirements

• Definition of CGMES profiles (equipment, topology, steady‑state, state variables, geographical, diagram/layout, dynamics, etc.).
• Rules for profile contents, relationships and mandatory/optional elements for interoperable exchange.
• Model Authority Sets (MAS) concept for identifying authoritative data sources and resolving multi‑source merges.
• CIM extensions and mapping guidance to ensure consistent use of CIM parts across CGMES profiles.
• Serialization, validation, and conformance rules (including references to CIMXML/model exchange formats).
• Governance and versioning considerations for assembled and merged grid models.

Typical use and users

Used by transmission and distribution system operators, model authorities, utility data exchange teams, software vendors of EMS/SCADA/market/analysis tools, consultants and integration teams to exchange and merge network models reliably between organizations and tools. It supports off‑line and operational planning model exchanges, model rollups for regional studies, and multi‑vendor interoperability testing.

Q: What does it cover?

A: It covers CGMES profile definitions, profile constraints, serialization and validation rules, Model Authority Sets, CIM extension usage, and governance/versioning guidance for interoperable model exchange (but not business processes or internal application design).

Q: Who typically uses it?

A: Transmission and distribution system operators, model authorities, EMS/SCADA/market/analysis software vendors, integration teams and consultants involved in power system model exchange and multi‑vendor interoperability.

Q: Is it current or superseded?

A: IEC 61970-600-1:2021 is the current edition and replaces the earlier IEC/TS 61970-600-1:2017 technical specification. National and regional bodies list the 2021 edition as the active standard.

Q: Is it part of a series?

A: Yes — it is part of the IEC 61970 EMS‑API family and the 600‑series of documents that implement the CGMES approach; other parts include profile definitions, CIM base/dynamics parts and the CIMXML model exchange formats.
