Overview
IEC 61968-4:2007 defines message content and system interfaces for records and asset management in electric utility distribution management. Part of the IEC 61968 series, this standard specifies a set of interoperable message types to exchange network, asset and catalogue information between loosely coupled applications in a Distribution Management System (DMS). It is of core relevance to Smart Grid implementations that require consistent, standardized data exchange for planning, operations and asset lifecycle management.
Key topics
- Message types: standardizes content for Network Data Set, Change Set, Presentation, Asset List, Asset Catalogue and Type Asset Catalogue messages.
- Static information model: message fields are drawn from a common information model (CIM classes), ensuring consistent attribute names and types across systems.
- Interface reference model: aligns with the IEC 61968-1 IRM to support inter-application integration for distribution management.
- Loose coupling and middleware: intended for heterogeneous environments where applications communicate via message exchange (not tight, intra-application middleware).
- Data referencing: messages may include identifiers that reference external documents or catalogues (e.g., assets, type catalogues) rather than duplicating full definitions.
- Formats & use cases: defines formats for created/changed/shown/deleted NetworkDataSet messages and others to support typical records workflows.
- Smart Grid relevance: supports integration needs for modern grid monitoring, planning, and asset inspection processes.
Applications
IEC 61968-4 enables practical utility use cases such as:
- Network extension planning - exchanging proposed “as-planned” or “as-built” feeder data between planners and analysis tools.
- Copying feeder or network data - transferring portions of the network model between systems (GIS, DMS, planning tools).
- Network/diagram edits - publishing change sets and presentations for collaborative editing and version control.
- Asset inspection and lifecycle management - sharing asset lists and catalogues for maintenance, procurement and field work.
These message types support exchanges occurring on operational timescales (seconds to hours), complementing batch or warehouse solutions.
Who should use it
- Utility IT architects and data modelers
- DMS, GIS and asset management vendors and integrators
- System integrators implementing Smart Grid interfaces
- Network planners, asset managers and operations teams
