CIM Issues #4806
ERCOT angle difference limit setAngleDifferenceLimitSet -
Description
ERCOT angle difference limit set
AngleDifferenceLimitSet - Use case needed. Use case is specification of angle differences monitored in real-time but determined based on stability analysis. Possibly could use LimitSet for this same functionality.
Proposed Solution
In order to cover use cases for coordinated security analysis ENTSO-E also extended OperationalLimits with class
VoltageAngleLimit - Voltage angle limit between two terminals. The association end OperationalLimitSet.Terminal defines one end and the host of the limit. The association end VoltageAngleLimit.AngleReferenceTerminal defines the reference terminal.
It has association with Terminal
It has attribute value and normalValue - The difference in angle degrees between referenced by the association end OperationalLimitSet.Terminal and the Terminal referenced by the association end VoltageAngleLimit.AngleReferenceTerminal. The value can be positive, negative or zero depending on the angle difference between the two terminals.
Proposal to add this to CIM18 and close this issue which should also cover ERCOT issue.
Oslo 15 June 2023 - agreed. Should be reviewed for approval.
Decision
The issue was part of the 2 weeks review process in July 2023. There were no comments and it is concluded that the extensions are integrated in CIM18.
Release Notes
VoltageAngleLimit class added to the OperationalLimits package.
VoltageAngleLimit - Voltage angle limit between two terminals. The association end OperationalLimitSet.Terminal defines one end and the host of the limit. The association end VoltageAngleLimit.AngleReferenceTerminal defines the reference terminal.
It has association with Terminal. It has attribute isFlowToRefTerminal.
It has attribute value and normalValue - The difference in angle degrees between referenced by the association end OperationalLimitSet.Terminal and the Terminal referenced by the association end VoltageAngleLimit.AngleReferenceTerminal. The value can be positive, negative or zero depending on the angle difference between the two terminals.
Attributes normalValue and isFlowToRefTerminal are added to EQ profile in 452. Attribute value is added to SSH in 456.
