Marv Landauer Report to TSS on Annual Study Program Report Review Task Force April 2012 TSS Meeting Salt Lake City
Purpose • The purpose of this initiative is to evaluate the usefulness of the current Study Program Report and recommend improvements • There is an increasing need from other WECC groups for TSS to perform specialized studies • Avoid duplicative or unnecessary work • The new NERC Reliability Standards require Transmission Planners and Planning Coordinators to perform coordination studies traditionally done through the development of the Study Program Report
TSS Annual Study Program Task Force Task Force was created by TSS at August 2011 meeting to review Annual Study Program Report Task Force Membership: Marv Landauer, ColumbiaGrid, Chair David Franklin, SCE Mark Graham, TSGT Branden Sudduth, WECC Tracy Rolstad, AVA Craig Quist, PAC Ann Finley, MWD Philip Augustin, PGE Kent Bolton, WECC Riken Shah, NWE John Gross, AVA Gordon Comegys, ColumbiaGrid
Process • Presentation at January TSS Meeting • With feedback from TSS and PCC, drafted paper entitled “WECC Annual Study Program for TSS Discussion” prepared for comment. • Posted on TSS meeting page • Group is looking for comments today and will revise document accordingly
Draft Recommendations • Annual Study Program will include creation of quality base cases • Annual Study Program will no longer include RAS/Path Studies • Annual Study Program will include one special study from survey responses • System Assessment Summaries will be collected and compiled • Study Program should be reviewed biennially
1. Quality Base Cases • A group of outages including power flow and post-transient studies will be run on each base case as it is completed as a quality check and part of the final case review. • 18 outages compiled from previous study programs will be run • switching files for the 18 outages are needed • The Study Program Subgroup of SRWG will review this list annually to ensure it is current. • No performance log items will be identified from these outages. • If a violation occurs, the owner of the facility will determine whether the violation is acceptable or whether data corrections are necessary. • What is reported with each base case will need to be determined.
2. RAS/Path Studies • The Annual Study Program will no longer include RAS and Path studies. • RAS/Path owners will be responsible to stress base cases and analyze outage studies to test RAS and paths to show compliance to PRC-012 through 014.
3. Special Studies • The Annual Study Program will include one special study each year from the annual survey responses. • 2012 will include VGS/TEPPC Study Request
4. System Assessments • To meet Standard TPL-005 (today) or TPL-001-2 (future replacement of TPL-005), each utility shall provide WECC an Executive Summary of their TPL system assessments which WECC will compile into a single document. • These assessments will identify transmission issues on eachutility’s system, especially those that impact other utility’s systems. • Subsequent Annual Progress Report submission will include a correlation between these identified transmission issues and the planned projects.
4. System Assessments (cont.) Current Standard: Standard TPL-005 B. Requirements R1. Each Regional Reliability Organization shall annually conduct reliability assessments of its respective existing and planned Regional Bulk Electric System (generation and transmission facilities) C. Measures M1. The Regional Reliability Organization shall provide evidence to its Compliance Monitor that annual Regional and Inter-Regional assessments of reliability for seasonal, near-term, and longer-term planning horizons, and special assessments, were developed and provided as requested by other Regional Reliability Organizations or NERC.
4. System Assessments (cont.) Expected future Standard: Standard TPL-001-2 — Transmission System Planning Performance Requirements R2. Each Transmission Planner and Planning Coordinator shall prepare an annual Planning Assessment of its portion of the BES. This Planning Assessment shall use current or qualified past studies (as indicated in Requirement R2, Part 2.6), document assumptions, and document summarized results of the steady state analyses, short circuit analyses, and Stability analyses. R8. Each Planning Coordinator and Transmission Planner shall distribute its Planning Assessment results to adjacent Planning Coordinators and adjacent Transmission Planners within 90 calendar days of completing its Planning Assessment, and to any functional entity that has a reliability related need and submits a written request for the information within 30 days of such a request. 8.1. If a recipient of the Planning Assessment results provides documented comments on the results, the respective Planning Coordinator or Transmission Planner shall provide a documented response to that recipient within 90 calendar days of receipt of those comments.
5. Study Program Reviewed Biennially • The study program report should be reviewed on a regular basis (biennially)
Stressed Base Cases • PCC Action Item for TSS: • Is it important to create stressed base cases? • Should SRWG produce stressed base cases or normally dispatched, less stressed cases along with the development of new tools designed to increased stress on specific paths for individual use?
