Description

Current use of OperationalLimitSet.name or OperationalLimit.name to hold the condition of the limit; such as Emergency Limit or Normal Limit or LoadShed Limit becomes a "person viewable" nice solution, but not a machine readable nice solution. Having a new attribute in OperationalLimitType either as a flexible String data type, or of an enumeration of the most common types of limits would enhance the use and determination of the types of limits.


Decision

07-Feb-2024 Discussed in the weekly call:

Open question: Are we willing to make breaking changes (via a new proposal)? Or are we going to adapt what we have today (via Becky's suggestions)

DECISION TODAY:

Include Becky (and any others interested) to carve out an hour to discuss details. Needed for that discussion would include:

- Becky to provide descriptions relevant to each proposed enum literal (with follow on review from WG13 next week)
- Practical use cases to support each literal being recommend.

Upon review after that hour we should have enough information to proceed with what to add.

Can this request be modified to instead add LimitKind enum values that are used by the new attribute "kind" which was added to support the ENTSO-E extensions? Can additional enum values be added to the "LimitKind" enumeration to support the typical set of limits for "Emergency", "Normal", "LoadShed"? The LimitKind defined in the model CIM_Grid18v09_Support14v00_Market04v14.eap already includes "highVoltage", "lowVoltage", "operationalVoltageLimit", "alarmVoltage", "warningVoltage" and "stability".
