  1. MSRATF Update to TSS(Modeling SPS and RAS Ad Hoc Task Force)ActivitiesAugust, 2013 Joe Seabrook Puget Sound Energy, Inc.

  2. MSRATF Engagement • MSRATF formed in August by TSS upon assignment from PCC Chair – Responsive to Sep 8, 2011 event (Perform contingency events in WECC cases across the system with a few mouse clicks) • Details in Needs Statement, Scope Statement approved by PCC • Includes vendor participation by GE, Siemens/PTI, PowerWorld, V&R, and PowerTech • WECC groups helping include TSS, RPSOTF, MVWG, SRWG, RASRS, Relay WG • WECC web site for documents: WECC > Committees > Standing Committees > PCC > TSS > Documents > MSRATF Documents http://www.wecc.biz/committees/StandingCommittees/PCC/TSS/Shared%20Documents/Forms/AllItems.aspx

  3. MSRATF Meetings • Since August 2012, 6 face-to-face meetings and many WebEx sessions • Formed three subgroups with vendor representation in each group • RAS • Relays (Modeling Sequence Component Networks) • Contingency Definitions (Breaker Node Topology) • Additional • Breaker Node Topology • Modeling Sequence Component Networks

  4. RAS Subgroup James O’Brien (BPA) • Developing a Generic RAS specification • MSRATF approved on Tuesday 8/7 • Seeking MVWG comment and approval With WebEx (8/26 at 2:00 Mt time) • Seeking TSS comment and approval With WebEx (9/5 at 2:00 Mt time) • Donald Davies will be emailing to you this week.

  5. RAS Subgroup James O’Brien Colstrip owners are developing an ATR specification PAC is beginning to develop a Bridger RAS specification Jason Wilson presented an overview of the Bridger RAS 5

  6. RAS Subgroup James O’Brien • To demonstrate responsiveness to 9/2011 Outage Report recommendations we are asked to post and share Conditional RAS model files we currently use: • Send RAS files to Enoch by 8/21 to post • Under 2013 Base Cases, folder at bottom of web page: Contingency and Remedial Action Scheme Files (Various Formats) • Template for RAS descriptions also being developed for later, starting with WAPS

  7. Relays Subgroup Amos Ang (SCE) • Amos is new chair, taking over for Tracy • 3Φ Over-Current, non-directional Relays • MVWG approved existing relay models for WECC • MSRATF & MVWG approved spec for 3Φ, non-directional, curves and equations Over-Current relay (use for RAS) • Power Flow (steady-state) & Transient Stability (instantaneous and inverse time) • Seeking TSS approval, then vendors will develop and jointly validate with WECC

  8. Relays Subgroup Amos Ang • TSS Motion: Approve generic specification for 3Φ, non-directional, curves and equations Over-Current relay!! • Next – Generic 3Φ Distance relay • After that – 3Φ, differential relays • Soon - 3Φ, directional component to overcurrent relay • Then – Model unbalanced sequence networks in WECC planning cases • And – 1Φ Directional Over-Current and Distance relays

  9. Contingency Definitions Subgroup Jonathan Young (CG) • Developed a Contingency Definitions generic specification • Contingency file will be common format, read (translated) by all programs • Editing, sorting, selecting would be done within the programs • Seeking TSS approval, then vendors will develop and jointly validate with WECC

  10. Contingency Definitions Subgroup Jonathan Young • TSS Motion: Approve generic specification for Contingency Definitions!! • Developing specification to import / export in Contingency Definitions in BCCS • Beginning to develop Breaker-Node Topology for WECC planning cases • Explore changes to contingency definitions and relay models (bus / branch)
