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
