Overview
IEC 62361-100:2016 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on power systems management and associated information exchange. This standard specifically addresses interoperability in the long term by defining a method to map Common Information Model (CIM) profiles to W3C XML Schema. This mapping facilitates the exchange of power system-related information as XML documents, where the data’s semantics are aligned with the IEC CIM and the syntax is governed by W3C standards.
By standardizing the mapping process between CIM profiles and XML schemas, IEC 62361-100:2016 enables consistent data representation, improved communication, and enhanced system interoperability across diverse power management and automation platforms. This aligns with ongoing efforts towards smarter, more integrated electrical grids worldwide.
Key Topics
-
CIM Profile Mapping
The standard elaborates on how CIM profiles-subsets of the IEC CIM representing specific power system concepts-are translated into XML Schema definitions. This helps system developers implement consistent XML message structures that accurately reflect the underlying CIM semantics.
-
XML Schema Representation
The document outlines detailed specifications on constructing XML Schemas from CIM profiles, including the use of namespaces, data types, and complex structures to ensure accurate syntax and semantic preservation.
-
Mapping Rules and Specifications
IEC 62361-100:2016 sets forth comprehensive mapping rules covering:
- Compound and structured classes from CIM to XML complex types
- Basic and simple types conversion conforming to XML Schema data types
- Handling enumerations, code lists, and other specialized CIM constructs
- Naming conventions, documentation inclusion, and stereotype annotations
- Traceability between original CIM elements and their XML Schema counterparts
-
Profiling and Contextual Modeling
The standard introduces a profiling process and contextual modeling approach to tailor CIM subsets for targeted applications, supporting modular and scalable XML schema generation.
-
Modular Schema Design
Annexes in the document discuss the use of dedicated XML schemas for data types, enumerations, and code lists to promote modularity and reuse, thereby reducing complexity in schema management.
Applications
-
Power Systems Interoperability
By enabling the direct translation of CIM profiles into XML schemas, IEC 62361-100:2016 facilitates interoperability among control centers, substations, and Distributed Energy Resource (DER) management systems. This consistency aids real-time data exchange and operational coordination.
-
Data Integration & Exchange
The standardized XML document format supports seamless information sharing across utility systems, vendors, and regulatory bodies while preserving data meaning, enabling better analytics, reporting, and decision-making.
-
AMI and Smart Grid Solutions
Mapping CIM to XML Schema is critical in Advanced Metering Infrastructure (AMI) and smart grid applications where diverse equipment and software must communicate efficiently using standardized data models.
-
Software Development & Vendor Compliance
Software vendors can leverage these standardized mappings to develop compliant applications, reducing integration risks and accelerating deployment cycles in power system automation environments.
