Purpose of this Focus Community
The purpose of this community is to develop and enhance CIM standards to support the accurate modeling and exchange of short circuit and geomagnetic disturbance (GMD) data within the IEC 61970 framework. This effort enables utilities, vendors, and planners to represent fault current contributions, equipment withstand ratings, grounding configurations, and system parameters critical to short circuit studies and GMD impact analysis. The community focuses on aligning CIM with industry practices and regulatory requirements for grid protection, planning, and resilience. By standardizing how this data is captured and shared across platforms, the CIM Short Circuit & GMD Data Focus Community plays a key role in improving system protection coordination, reducing modeling discrepancies, and enhancing the reliability of the bulk power system in the face of extreme events.
Various activities meet with various cadences:
- Biweekly (virtual): Subcommittees on use-case data modeling or testing & certification
- Monthly (virtual): General Focus Community update
- Ad-hoc (virtual): Marketing subcommittee for any upcoming User Group meetings or events
- Annually (in-person): Meet-up at one or more UCA User Group meetings
The CIM Short Circuit & GMD Data Focus Community is comprised of a diverse mix of energy industry stakeholders including electric utilities, hardware and software vendors, research labs, federal government, and consultants. These dedicated individuals contribute as they are able and participate in activities based on interest and ability.
