  1. Introduction • Tracy Rolstad • Avista System Planning • BSEE, Idaho, 1992 • Graduate Diploma, Naval War College, 1999 • Chair of WECC PowerWorld User’s Group • Contact Information • 509 495 4538 • tracy.rolstad@avistacorp.com

  2. FERC Order 754 • http://www.nerc.com/docs/standards/dt/Order_754-Request_for_Data_or_Information_08162012.pdf

  3. Planner’s Deliverable

  4. Performance Measures

  5. How Can We Do This (Quickly)? • One Line Diagrams? • Accurate, but… • Do you REALLY want to squint and count lines?

  6. Or…Use PWS • Filters (ownership AND) • Buses at 200 kV or higher with 4 or more ckts • Buses 100 to 200 kV or higher with 4 or more ckts • Buses 100 kV and up, with aggregate bus fault load loss of 300 MW • Buses with aggregate generation of 1000 MW or higher

  7. Step by Step… • Figure out ownership • Build filter for 200 kV and 4 ckts • Save filter

  8. Identify Ownership

  9. 200 kV & 4 or more ckts

  10. Auxiliary File (BPA/200kV/4ckt) DATA (FILTER, [ObjectType,FilterName,FilterLogic,FilterPre,Enabled]) { "Bus" "FERC 745: 200 kV and 4 ckts or more" "AND" "NO " "NO " <SUBDATA Condition> OwnerName contains "Bonneville" BusNomVolt >= 200.00000 BusNeighbors:1 >= 4 </SUBDATA> }

  11. Filter BPA/200 kV/4 ckts Results 12HS4A Ops Case yields 99 buses

  12. As a matter of form, run ctg

  13. Insert Contingencies

  14. Power Flow Contingency Results Not required by FERC 754,but the results are easily obtained and have some value.

  15. Identified Need: Ctg Converter DATA (CONTINGENCY, [CTGLabel,CTGSkip,CTGProc,CTGSolved,CtgFileName,LoadMW,GenMW,QVAutoplot,CTGViol, CTGViolMaxLine,CTGViolMinVolt,CTGViolMaxVolt,CTGViolMaxInterface]) { "Bus (>200kV and >4 ckts):040323CUSTERW500" "NO " "YES" "NO " "none" "" "" "NO " Unsolved "" "" "" "" <SUBDATA CTGElement> "BUS 40323 OPEN" "" CHECK </SUBDATA> Need a automated way to convert power flow contingencies to stability events. OR Need an automatic insert tool for transient stability events. DATA (TSCONTINGENCY, [TSCTGName,StartTime,EndTime,UseCyclesForTimeStep,TimeStep,CTGSkip,CTGSolved, CTGViol,TSTotalLoadMWTripped,TSTotalGenMWTripped,PLVisible,PLColor, PLThickness,SODashed,SymbolType]) { "Custer 500 kV bus" 0.000 10.000 "YES" 0.500 "NO " "NO " 0 0.000 0.000 "YES" -1 Default "Default" "Default" } DATA (TSCONTINGENCYELEMENT, [TSCTGName,TSTimeInSeconds,WhoAmI,TSEventString,Enabled,FilterName]) { "Custer 500 kV bus" 1.000 "Bus '40323'" "FAULT 3PB SOLID" "CHECK" "" "Custer 500 kV bus" 1.100 "Bus '40323'" "CLEARFAULT" "CHECK" "" }

  16. PWS to Excel to PWS The End The Beginning

  17. PWS to Excel to PWS.. Manual cell fill Manual cell fill From ctg tool =CONCATENATE("Bus Fault ",MID(A3,4,9)) =CONCATENATE(LEFT(A3,3)," '",MID(A3,4,9),"'")

  18. PWS to Excel to PWS.

  19. PWS to Excel to PWS… • The table below gets us halfway…we still need clearing times • We need two spreadsheets • Fault on (time, nature of fault) • Clear fault (time, clear fault, open breaker)

  20. PWS to Excel to PWS…. • Cut and paste, add clear time and new description

  21. PWS to Excel to PWS….. • Cut and paste to make this spreadsheet

  22. Pasting into PWS.

  23. Pasting into PWS..

  24. Refresh by Switching to Multiple

  25. Paste in Clearing

  26. Final Result (Bus Fault/Clear) • With practice, 2 minutes to get here.

  27. Filter (200 kV/4 ckts) DATA (FILTER, [ObjectType,FilterName,FilterLogic,FilterPre,Enabled]) { "Bus" "FERC 745: 200 kV and 4 ckts or more" "AND" "NO " "NO " <SUBDATA Condition> OwnerName contains “INSERT OWNER NAME HERE" BusNomVolt >= 200.00000 BusNeighbors:1 >= 4 </SUBDATA> }

  28. Filter (100-200kV/6 ckts) DATA (FILTER, [ObjectType,FilterName,FilterLogic,FilterPre,Enabled]) { "Bus" "FERC 745: 100 kV to 200 and 6 ckts or more" "AND" "NO " "NO " <SUBDATA Condition> OwnerName contains " INSERT OWNER NAME HERE " BusNomVolt between 100.00000 200.00000 BusNeighbors:1 >= 6 </SUBDATA> }

  29. Filter (100 kV/4 ckts-300 MW) • Apply 100 kV and up and 4 and up ckt filter • Run DC ctg analysis WECC wide • Think REAL HARD about load modeling practices

  30. Consider Disaggregating Loads

  31. Filter (Buses-gen>1000) DATA (FILTER, [ObjectType,FilterName,FilterLogic,FilterPre,Enabled]) { "Bus" "FERC 754: Gen > 1000 MW at bus" "AND" "NO " "YES" <SUBDATA Condition> GenMWMax >= 1000.00000 </SUBDATA> }

  32. Performance Measures

  33. Performance Measures. • Absolute Angle Deviation for Loss of Sync

  34. Performance Issues

  36. Questions/Thoughts? • This IS a workshop topic • We can walk the dog through this tomorrow • Best practices for things like FERC 754 • Should you model large aggregate loads? • Consider modeling additional buses, network if appropriate • Other tools: Connections • Cut/paste works in Transient Stability • Really easy for bus fault insertion • A bit more complicated for line faults
