  1. Tracy Rolstad TSS Chair TSS Chair Report July 2014 Salt Lake City, UT

  2. Overview • Approval Items • 2015 Base Case Schedule • TSS Activities • Includes MSRATF activities • JUG • MVWG Activities • SRWG Activities • 2015 Base Case Schedule • DPM Changes (consider up or down vote in future) July 2014

  3. TSS ACTIVITIES • CIP-014-01, MOD-032-1, TPL-001-04, TPL-07 • Response to 08 Sept 2011 AZ to CA Outage • Relays, DPM Changes, WECC RAS/Ctg Definition • BCCS • Base Cases created by BCCS in 2015. • Training provided in 2013 and available in 2014 • Certification/de-certification Process of Study Software • Following MSRATF software requirement development…will assign to JUG July 2014

  4. TSS: Projects Coordination • Mostly quiet July 2014

  5. TSS: Response to AZ to CA Outage • Sharing of Contingencies and RAS files • Began in 2013, TSS to ask for this again this fall • WECC RAS/Contingency Format/File • Proposal to have vendor assist WECC in creating this for 2015 base cases (start in 2014) • Outcome would be a WECC wide RAS/Ctg file that functioned for each WECC published base case. July 2014

  6. TSS: Joint Users Group • To assume all MSRATF duties fall of 2014 • Intend on disestablishing MSRATF Jan 2015 • JUG should be the open and transparent forum for allocating WECC funds for study software development • New or changing standards require JUG be PROACTIVE • Work within TSS framework to meet requirements of standards July 2014

  7. SRWG ACTIVITIES • 2014 Base Cases • Attempted to develop jointly with BCCS and without • BCCS work in progress (2015 success date?) • Data Preparation Manual • Rant Ahead: • Propose to ask for straight up and down vote on DPM. Edits are destroying the timeliness. • MOD-032-01 (Short circuit discussion) July 2014

  8. SRWG Logs • Rep Log • Shows steady improvement until we reset it with new data checks • This is an on going trend • Recall that “Performance Log” has gone away • Morphed into a listing of study results listed in Annual Study Program report. July 2014

  9. SRWG: 2015 Base Case Schedule • Operating base cases • 2015-16 Heavy Winter • 2015-16 Light Winter • 2016 Heavy Spring • 2016 Heavy Summer • 2016 Light Summer • Five year base cases • 2021 Heavy Summer • 2020-21 Heavy Winter • Ten year base cases • 2025-26 Heavy Winter • 2026 Heavy Summer July 2014

  10. July 2014

  11. SRWG: Short Circuit Data • MOD-032 asks for short circuit data • Voted at TSS and passed for DPM changes • Members supply short circuit data that is consistent with steady state data • Waiting for SRWG proposed DPM changes on this • Much debate at TSS meeting and subsequent to it • Some desire for re-voting • MOD-032-01 requires changes in data submission practices • DPM agility needed! July 2014

  12. MOD-032-01: R1. Each Planning Coordinator and each of its Transmission Planners shall jointly develop steady-state, dynamics, and short circuit modeling data requirements and reporting procedures for the Planning Coordinator’s planning area that include: 1.1. The data listed in Attachment 1. 1.2. Specifications of the following items consistent with procedures for building the Interconnection-wide case(s): 1.2.1. Data format; 1.2.2. Level of detail to which equipment shall be modeled; 1.2.3. Case types or scenarios to be modeled; and 1.2.4. A schedule for submission of data at least once every 13 calendar months. 1.3. Specifications for distribution or posting of the data requirements and reporting procedures so that they are available to those entities responsible for providing the data. MOD-032-01: R4. Each Planning Coordinator shall make available models for its planning area reflecting data provided to it under Requirement R2 to the Electric Reliability Organization (ERO) or its designee to support creation of the Interconnection-wide case(s) that includes the Planning Coordinator’s planning area July 2104

  15. SRWG: Nuances of MOD-032-01 • Nuances • “…steady-state, dynamics, and short circuit modeling data requirements...” • “…for building the Interconnection-wide case(s)…” • “Data must be shareable on an interconnection-wide basis to support use in the Interconnection-wide cases.” • Practically speaking this suggests WECC map short circuit data to power flows cases. March 27, 2013

  16. SRWG: Data Preparation Manual • WECC can not continue its present DPM approval practices • TSS (SRWG) is asking for up or down vote • No more editing of SRWG’s unless grossly incorrect • Edits happen at TSS and PCC, then back to SRWG for changes…it takes MONTHS to do this! • Everyone here has representation on SRWG • Are you communicating to them? • Do you have the right person there? • Does your SRWG understand your company’s position? July 2014

  17. MVWG ACTIVITIES • Continued work on Composite Load Model • Open Question: Are we there yet? • Updates to the Approved Dynamics Model List • 2 generation wind, 1st generation PV • Approved WECC Modeling Guidelines for PV and Wind • White Paper on Transient Voltage Performance • Kosterev and Undrill July 2014

  18. TSS Report Summary • 2014/2015: • BCCS • Composite Load Model, phase 1 • Relays, Ctg & RAS Definition • Short Circuit Data submission to WECC • MSRATF disestablishment in 2014 • DPM Up or Down Vote PLEASE! • Agility in responding faster to external forces • FERC/NERC, etc • Physical Security and GIC Data and Study Needs • TSS Guidance on CIP-014 in progress July 2014

  19. Questions/Suggestions/Comments July 2014
