1 SRWG Chair Report March 2015 WECC HQ John Gross SRWG ChairSRWG Chair ReportMarch 2015WECC HQ
2 Topics Where are we headed? Data Preparation Manual status MOD-032 implementation plan and associated DPM2015 Base Case Compilation Schedule statusBase Case Coordination SystemModel Implementation ScheduleRenewable generation dispatchBalancing Authority Area representationWECC contingency analysisRAS Workshop and File Format specificationsMOD-033 coordination with MVWG
3 Where are we headed? What is the point of SRWG’s efforts? Provide data to support study requirementsChanges on their way (or already here)Node-breaker representationRAS and contingency modelingRelay emulationHow should we react?Develop staged implementation plansGet ahead instead of behind
4 Data Preparation Manual TSS approved 4 digit zone numbersAlso included technical writer editsRev 44 Digit Zone additionNon-BCCSRev BCCS-44 Digit Zone additionRev BCCS-5MOD-032 ImplementationBCCSDPM Revisions
5 MOD ImplementationTSS approved SRWG’s implementation plan and associated DPMFocus will begin shifting to Planning CoordinatorsHow to collect data from non-registered entities?
6 2015 Base Case Compilation Schedule TSS approved revisions to 2015 scheduleLoad descriptionShifting summer operating casesSeparate approved item to replace TEPPC case with 10 year light load caseRequested by WestConnect, NTTG, ColumbiaGrid, and California ISO
7 Base Case Coordination System Patch provided following December meeting did not resolve all critical issuesSiemens has hired a consultant to support troubleshooting issuesFurther update?
8 Model Implementation Schedule New approved modelsccomp – cross current compensationNeed to add to implementation schedule?
9 Renewable Generation Dispatch TSS is requesting renewable generation to be dispatched to non-zeroNot realistic for all renewables to be offWhen end-users turn them on, models cause problemsRepresent realistic output for scenario
10 Balancing Authority Area Representation TSS and MVWG support including BA representation in base casesSimilarities to Westwide System ModelMore closely mimics actual system controlsComparison to L&R submittalsImplementation pending software development and utilizing the new versionsOr changing existing Areas in cases to BA’s, no software changes required
11 BA Representation Demo Create new AreaMove buses to new Area by filterSelect an Area slack busChange control to Area SlackSet interchange for new Area to ACE ErrorAttempt to match existing solutionUnspecified interchanges absorbed at slack
12 WECC Contingency Analysis WECC Staff is continuing to run contingency analysis on operating base casesSRWG will support data collection efforts as needed
13 RAS and Contingency Modeling April 2, 9-11 MDT (Webinar)Intro to RAS modeling and RAS/contingency file formatTypes of RAS that can be modeledMay (Salt Lake)In person workshopCreate models of your specific RAS for usePE continuing education credits available
14 MOD-033-1 Implementation Plan SRWG was directed to work with MVWG to develop an implementation planCompare planning power flow model to state estimatorCompare planning dynamic model to actual system responseMerging WSM and planning model?
