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 references
  • rmatrix, xmatrix, cmatrix — PerLengthPhaseImpedance
  • Seasons, Ratings — seasonal OperationalLimitSet

EnergyConsumer / Load (30 of 42 attributes TODO)

Key gaps:

  • yearly, daily, duty, growth — LoadShape → DayType/Season mapping
  • CVRwatts, CVRvars — LoadResponse voltage exponent model
  • Various load-class and reliability attributes with no CIM equivalent

Cross-Cutting

  • Hardcoded 60 HzC = 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.
