3. Modeling and Data Management Strategy
Proposed Project Prioritization
Already executing
SRWG Training Sessions
Posting cases in PowerWorld
Combine like cases in compilation schedule (pilot)
Up next
Review, document publically, and potentially update WECC case build and validation process
Revisit/develop process for WECC to reject/document suspect bad data
Work to further align with the WSM model
More to come…

4. Modeling and Data Management Strategy
ACTION:
Need volunteers to chair and staff a Task Force
Task Force will focus on one project and then be disbanded to provide multiple opportunities to SRWG members to participate
First project should be Review, document publically, and potentially update WECC case build and validation process
Will need WECC as part of the TF

Usually is direct (LLL) to REMEDIAL ACTION.
“OUTAGE”
Outage driven SPECIAL ARMING CONDITIONS
RAS group: Line Name: deploy/outage (as necessary)

Modeling RAS – At BPA
Assumptions
Recursive issues determining arming set points
Solution: Max Gen Drop at
Min arming point
Propose only including with
Operations cases
Master RAS file
maintained as one file
Western Electricity Coordinating Council

15. Modeling RAS – WECC Issues
Storage Location
Different location from base cases
Restricted access to only NERC registered entities
As one master file similar to master dyd
Submissions/Maintenance
As data changes similar to master dyd
Mapping to cases
Each mapped RAS file stored in the secured location with similar file structure to base case page
Only mapping to Operations cases (for now)
