Full title and description

IEC 61970-600-2:2021 — Energy management system application program interface (EMS-API) - Part 600-2: Common Grid Model Exchange Standard (CGMES) - Exchange profiles specification. This International Standard defines the CGMES exchange profiles used to describe, package and exchange power system models (including topology, equipment data and diagram/GIS information) for power flow, short‑circuit and dynamic studies and other grid‑modeling applications.

Abstract

IEC 61970-600-2:2021 specifies the structure, content and constraints of the exchange profiles that make up the Common Grid Model Exchange Standard (CGMES). The document aligns CGMES profiles with IEC 61970-450 series and IEC 61968-13 where possible, provides specific profile definitions where referenced profiles were not yet published, and includes machine-readable profile documentation to support model-driven development. It preserves backward compatibility with earlier CGMES versions while addressing TSO/DSO modelling needs for accurate power system analysis and data exchange.

Scope

This part of IEC 61970 defines the exchange profiles that form the Common Grid Model Exchange Standard (CGMES). It describes required data sets, constraints and profile-specific rules used to exchange consistent and validated network models between Transmission System Operators (TSOs), Distribution System Operators (DSOs), market participants and modelling tools. CGMES profiles cover topology, equipment parameters, voltage levels, connectivity, diagram and GIS data, and items required for power flow, short-circuit and dynamic studies. The standard also defines how CGMES relates to referenced CIM-based profiles (IEC 61970-450 series and IEC 61968-13) and provides machine-readable artefacts to support implementation and model-driven workflows.

Key topics and requirements

• Definition of CGMES exchange profiles and profile-specific constraints for accurate model exchange.
• Alignment and cross-references to IEC 61970-450-series and IEC 61968-13 profiles; explicit profile definitions where needed.
• Machine‑readable documentation (RDFS and related artefacts) to support automated, model‑driven implementation and validation.
• Requirements to support power flow, short‑circuit and dynamic studies, including necessary attributes and topology rules.
• Guidance for exchanging diagram and GIS data alongside electrical model data.
• Measures for backward compatibility with earlier CGMES/Profile versions (including handling of the EQBD profile and its deprecation/alignment notes).
• Constraints and restrictions applied when a CGMES profile narrows or extends referenced CIM profiles.

Typical use and users

Primary users include Transmission System Operators (TSOs), Distribution System Operators (DSOs), power system modelers, utility IT and data‑exchange teams, software vendors (EMS/SCADA/market/dynamic simulation tools), system integrators and researchers involved in grid modelling and simulation. The standard is used when exchanging network models between organizations, populating simulation tools, performing cross‑border or multi‑vendor studies, and implementing model‑driven data workflows.

Implementers often consider IEC 62325 and IEC 61850 when integrating market or substation data flows.
