1. 1 MSRATF Update to TSS (Modeling SPS and RAS Ad Hoc Task Force) Activities May, 2014 Joe Seabrook Puget Sound Energy, Inc.

2. 2 MSRATF Documents WECC web site for documents: WECC > Committees > Standing Committees > PCC > TSS > Documents > MSRATF Documents

3. 3 MSRATF Meetings Subjects –Relays –RAS –Contingency Definitions –Breaker Node Topology –Modeling Sequence Component Networks ♣Include the means to exchange between simulation programs - for all models ♣All data – provided and maintained by the sanctionable entity, TO, TP, PC, TOP

4. 4 RAS Subgroup Thong Trinh Generic RAS model & Common Format –Implemented in PowerWorld last fall –GE/WECC contract to implement in 3 phases To provide Phase 1 this fall (RAS) –Seeking an agreement with Siemens-PTI –Thong and Eleanor Ewry are testing the PowerWorld implementation Bug fixes and improvements Want others to test

5. 5 RAS Subgroup Others TSS is requesting members to provide their RAS descriptions and models - Tracy Colstrip transmission operator continues developing an ATR specification PAC is using generic RAS for Bridger BC Hydro is working with PowerWorld to attempt to use generic RAS

6. 6 Relays Subgroup Amos Ang Developing a differential relay model specification –Will submit it to MVWG for approval in June; then to TSS for approval in August –Is triggered off the contingency description, not unbalanced line flows –Node Breaker is required for bus differential Will begin developing generic model requirements for generator relays –Beginning with GP1 and GP2

7. 7 Node Breaker Subgroup Jonathan Young Approved Node-Breaker White Paper Writing a paper on Integration of BCCS and WSM from the TO, GO, TOP, TP, PC perspective –Includes Node Breaker modeling and Node Breaker bus view –Will become an SRWG document Principle: Facility owners model and maintain their own equipment (sanctionable)

8. 8 Node Breaker Subgroup Jonathan Young TSS Motion: In the Long ID use Label from WSM for each generator having a Label. Have “WSM_Mapping_GE_V9_May1.xlsx” from Slaven Kincic. –Labels for 95% of generation MW –TSS direction [ Explore changes to contingency definitions and relay models (bus / branch) ]

9. Modeling Unbalanced Networks TSS Motion: Include unbalanced sequence network data in WECC base cases. MOD-032 requiring fault data approved by FERC on May 1. –Requirements R1. July 1, 2015; Data R2. July 1, 2016 Some data also needed for GMD studies Can do category C & coordinate with neighbors Performs 1 ϕ faults with decaying currents See “Export ASPEN Sequence Data To PTI WECC Base Case”, May 14, 2013 9
