Description

Generic FACTS device modeling is currently not available and need to be supported, while only its specialty SVC is supported. It contains, e.g., Static Synchronous Series Compensator (SSSC), Unified Power Flow Controller (UPFC), Thyristor-Controlled Series Capacitor (TCSC), Static Synchronous Compensator (STATCOM), and etc.

Wiki Reference: https://www.sciencedirect.com/topics/engineering/flexible-ac-transmission-systems#:~:text=FACTS%20devices%20are%20static%20power,congestion%20management%20and%20loss%20optimization.

Proposed Solution

Initial Step: Review the FACTS device models and work out the draft UML for modeling them.
Note: ENTSO-E & Statnett has already worked on this and made good progress. Can become the basis for standardization.

The task is to present FACTS and control model and eventually add it in CIM18v04. The proposal is using the concepts discussed in Tom Berry's group/control discussions

Decision

Discussed during the 15-Feb-2023 meeting and the Action Items identified in the comments for this date must be executed first to determine a final proposal.

19-Sep-2024 Joint TF Hybrid Meetings - Minneapolis:
Revisited this one. Decided to delete the old and create a mapping script.

Release Notes

The following model changes were made for this issue:
  • The SVCControlMode enumeration was deleted from the canonical model.
  • The description of the existing StaticVarCompensator class was updated to align it with the new FACTS modelling.
  • The inheritance hierarchy for StaticVarCompensator was changed from RegulatingCondEq to now inherit from the new FACTSEquipment class.
  • All the existing attributes that were defined within the StaticVarCompensator class were deleted.
The attributes that were deleted are now replaced/mapped to the following new attributes/classes:
  • StaticVarCompensator.capacitiveRating -> FACTSEquipment.ratedC
  • StaticVarCompensator.inductiveRating -> FACTSEquipment.ratedL
  • StaticVarCompensator.q -> FACTSEquipment.q
  • StaticVarCompensator.slope -> FACTSEquipment.slope
  • StaticVarCompensator.voltageSetPoint -> VoltageControlFunction.targetValue
The following enumeration literals deleted with the removal of the SVCControlMode enumeration now map to:
  • StaticVarCompensator.sVCControlMode.reactivePower -> ReactivePowerControlFunction
  • StaticVarCompensator.sVCControlMode.voltage-> VoltageControlFunction
Profile impacts due to these model changes include:
  • Deleted the SVCControlMode enumeration from 452 EQ Core profile.
  • Deleted the StaticVarCompensator class from the SSH profile
