WECC Reliability Based Control Field Trial. Overview. Basic plan for the FT FT document – what’s new/different Roles & responsibilities Readiness - EMS changes? Data reporting Evaluation Questions. Who, what, when, where, how, why. All of us – BAs, RC, PWG, SDT
E N D
Overview • Basic plan for the FT • FT document – what’s new/different • Roles & responsibilities • Readiness - EMS changes? • Data reporting • Evaluation • Questions
Who, what, when, where, how, why • All of us – BAs, RC, PWG, SDT • Monitor, act, collect, report, analyze, summarize • March 1, 2010 – February 28, 2011 • Real-time & Historical • EMS Changes? Monitoring Tools? • Support the SDT and for “our” benefit
FT Document – Major Changes • Version 4 vs Version 8 • Potentially obfuscating changes have been addressed\ • ATEC is now a standard • ADI references have been removed • References to AGC status, suspension of control, response to BAAL violations have been revised • Revised Timeline – start date & milestones • Evaluation criteria expanded to monitor all paths • Loosened verification of BA operator readiness • Additional data collection/reporting to address WECC concerns
Who-What • All BAs with Peak Load or Max Gen > 500 MW must participate • All BAs must be able to meet the data collection reporting requirements in Appendix A. • ACE, Frequency related clock-minute values • Count minutes in different violation categories • All BAs will control to meet BAL-001 and BAL-007 • While CPS2 is waived, it must still be calculated • BAL-007 – a frequency based ACEclock-min limit (BAAL) with a 30 min time limit • BAs must still continue to calculate and report all NERC required quantities.
How-Why • No EMS modifications are required and BAs may “loosen” control within limits • “Loosen” control will differ depending on software • BAs can modify their EMS – if they wish • BAs can self-implement the BAAL calculation and monitoring of ACE or use tools provided by the SDT • The SDT tools are for monitoring only and reference the ACE history (e.g. a PI database) • BAs verify to PWG that Operators are trained in RBC • Support the SDT in assessment of RBC • Consider in WECC control metrics that reflect VGS
When - timeline • August 2009 – Workshop • September 2009 • PWG posts updated FT document • BAs begin preparing for FT • October 2009 • OC approves the FT plan and document • OC posts the FT plan for Board approval • December 2009 • Board approves FT plan
When – timeline continued • January 2010 • PWG conducts final workshop or conference call (TBD) • RC certify readiness • February 2010 • BAs annual update of frequency bias terms • BAs certify readiness • BAs forward 2 weeks of FT data to PWG/WECC • RC certifies all BAs are providing requisite data • PWG forwards list of participating BAs to SDT for CPS2 compliance waiver • PWG announces commencement of FT • March 2010 • FT begins 03/01/2010 00:00:00 CST • 3/15/2010 – BAs submit two weeks of data
When – timeline continued • April 2010 – March 2011 • BAs submit data • BAs note and describe circumstances where ACE exceed BAAL for more than 10 or 20 consecutive clock-minutes • PWG / SDT conference call and review of BA data • Open conference call – BAs may participate • Consider enhancements/improvements to the FT
