Model Coverage¶
This page summarizes which DSS elements and attributes are handled by the
bidirectional converter. Attribute-level detail is tracked inline in each
converter source file and in TODO.md at the package root.

Known Attribute Gaps¶
ACLineSegment / Line (22 of 42 attributes TODO)¶
The most impactful gaps are geometry-based line models:
geometry,spacing,wires,cncables,tscables— WireSpacingInfo / WireInfo referencesrmatrix,xmatrix,cmatrix— PerLengthPhaseImpedanceSeasons,Ratings— seasonal OperationalLimitSet
EnergyConsumer / Load (30 of 42 attributes TODO)¶
Key gaps:
yearly,daily,duty,growth— LoadShape → DayType/Season mappingCVRwatts,CVRvars— LoadResponse voltage exponent model- Various load-class and reliability attributes with no CIM equivalent
Cross-Cutting¶
- Hardcoded 60 Hz —
C = B / (2πf)in line and load converters uses a hardcoded 60 Hz; should be extracted from the circuit base frequency.
See TODO.md for the full gap list with CIM class mappings.
