5. ADS Case Build Discussion
SDWG Discussed Recommended Support of ADS Case
Option 1: Align the 10 heavy summer case with the needs of the ADS case
Not Preferred due to modeling differences
Option 2: Create a new case built off of the 10 year heavy summer case in the BCCS
Concerns that SDWG could not provide the needed data, scheduling issues, and resource issues
Option 3: Support the creation of a new case outside of the BCCS
Preferred pending additional information on data request

6. Generation Criteria Update
Current plan to model both Retail-Scale DER (R-DER) & Utility-Scale DER (U-DER)
U-DER Plan:
Model as generator
DER_A dynamic model for units greater than 5 MVA
R-DER Plan:
Use DER fields in load models
Comp Load Model + DER_A dynamic model for output greater than 5 MW
Recommend inclusion under 5 MW if data is available without dynamics model
Western Electricity Coordinating Council

7. Generation Criteria Update
Needed Follow Up:
Software Vendors – Provide visual change to bus views to show DER modeling, possible addition of data fields to load model, possible other visual changes to bus view
Survey for opinion on MW threshold
WECC testing
Recommendation to further distinguish DER types

8. Base Case Coordinator Activities
Specialized Case Request Template Finalized
2019 Annual Base Case Compilation and Data Check Scope of Work (Approved)
Looking into adjusting to be a living document
2019 Annual Base Case Compilation and Data Check Report (Approved)

9. Base Case Coordinator Activities
Confirmed that the newly added Light Spring Operating case is needed
Pursuing if it is need yearly or every other year
Study Survey showed no viable reason to change projected study years for planning cases
Did show a desire to produce near term planning cases
Looking at the resource requirements to expand the BCCS to include near term planning cases by combining them with operation case builds

10. Compliance Coordinator Activities
DPM Change Request: Base Case Modification Section
Adds section to DPM to describe process to modify/update approved WECC base cases.
See DPM change request
Request for Approval of Base Case Modification DPM Change Request

11. Compliance Coordinator Activities
SADD version 2 adopted by SDWG
Used the Data Check routine in PowerWorld
Expands on Owner and Area sorting
Includes Vmax/Vmin check
Requested Changes
Include Data Maintainer Filtering
Include If Vmax/Vmin was not provided
WECC requested to include several hundred more dynamic model parameter checks
Western Electricity Coordinating Council

12. Compliance Coordinator Activities
Continue to focus on improving data quality
Changes to approved base cases are now notified at SDWG meetings and working with PDWG to have them presented at their meetings
Reminder in the Fall to data owners to send in major changes that were identified to approved cases produced in the current schedule
Continue to work on updating the SADD and providing documentation on monitored metrics
Plans to have yearly educational workshops in the summer to provide support for data owner, data submitters, etc.
Future work planned on cleaning up the dynamic data

13. Base Case Data Improvement Project
Formerly referred to as the BATF follow up effort
Review of the “BATF Modeling and Data Management Strategy” document finished
SDWG Vice-Chair developed a spreadsheet to delegate actionable items to appropriate leadership team members
Spreadsheet sent out to SDWG for comments
Non-actionable items and items outside of the scope of SDWG to be assigned to chair to manage
Example: Software solution
Leadership team members to develop/execute plans to complete assigned tasks and request resources if needed after SDWG review

14. Western Electricity Coordinating Council
SAMS Update
Node Breaker Modeling Pilot
Pilot program to test node-breaker modeling techniques
Continue to work on hybrid testing in PSSE in the East Coast Model
Pursuing Node-Breaker options in year 2019 of SDWG Three Year Plan
MOD Review Group
Questionnaire being reviewed
No planned distribution date

Other Activities
Additional Upcoming Work:
Update Three Year Plan
Review Node-Breaker Modeling
Overlap Meeting with PDWG
Discussed coordination opportunities
Several of the issues stem from data quality issues seen in the cases
Station Service without “ss” id
Required by DPM
Compiling seasonal branch ratings due to PSSE three rating issue
Likely to be solved when WECC moves to PSSE version 34

19. Western Electricity Coordinating Council
Other Activities
Overlap Meeting with PDWG
Reviewed Gen Criteria
Other issues to work on
Modeling of Netted Gen/Negative Loads/Motor Loads
Some DS line models
Disaggregating CCCTs
Likely to continue
