Interchange Local Component

Self-Supply of Operating Reserves.

allow Powerex supplying Operating Reserves for any energy it purchases within the BPA control area, when and if called upon by BPA to deliver. Uses ICCP link

MW transfer is changing too much. Creates Angular Instability. L92 and L294 will detect a fault and protection will go off.

enables dyanmic schedule to CAISO to be included in AGC calculation.

Used to manually enter NSI when AGC gets suspended (suspended when 75MW change)

The selected AGC Mode determines how the Area Control Error is computed.

TLBC (Tie Line Bias Control): both Interchange Deviation and Frequency Deviation components are included in ACE computation. In addition, the WECC ATEC component is also included. This mode shall be used at all time unless system conditions require the use of other modes

BC Hydro ACE calculation.

NERC ACE adds the Gen Offset Scheduler

statistical measure of ACE variability and its relationship to frequency error;

statistical measure designed to limit unacceptably large net unscheduled power flows.

you need a certain amount of moving generators to provide inertia in case something fails. Cannot import too much energy compared to load.

• TC lowers the TTC to the TRMu
• curtailment manager will run
• Implement cuts
• inform GC

MODS: Daily Schedules, click new schedule at the bottom

e_Tag: Top right, click New Tag

MODS: Manual TSR entry

OASIS: Reservations -> New TSR

Remaining value in TSR

Tell them to ask another PSE.

Why? Shows favoritism.

• ·  FBC contacts the GC and tells them the MW requested and the start time of the delivery (the time of the contingency).
• ·          A second call should be placed by FBC when the delivery ends or if the MW amount changes.
• ·         The GC in turn should advise the Interchange Operator of the delivery times and amounts.
• ·         IPO then calculates an Integrated value and makes log entry.
• ·         FBC submits a form to the IPO via email to document the delivery. IPO should check the form for accuracy. if everything looks good, send email to SCM, Grid Ops After the fact and to Me stating that the document is accurate. If it is not accurate, advise the SCM and work with FBC to resolve the discrepancy. Keep a copy of the FBC email in the appropriate email folder in the RT Sched mailbox.

Phone Powerex quickly and ask what tags they want cut.

• tell them to refer to the website
• Tell the SCM to post what you told them on OASIS

Curtail all schedules on L71 TSRs.

Call Powerex and tell them to maintain schedules

Tell GC. He will adjust the dyanmic limit in AREVA

Tell them to call Powerex to submit tag and tell the GC. Approve the tag.

• NSI for AGC schedule
• TTC for both paths- OTC violation
• Interruptible contract info
• Capcity c ontract info
• dyanmic transfer limit

• GC will let you know
• May have to call California

alarms. Let GC know. AGC schedules not going to be passed. GC needs to run backup scheduler. GC needs to manually enter dyanimc transfer limit.

Call powerex and ask for Transmission adjust. Alberta has to approve. Then SL will go to zero. Give them the etag number

• Network economy transmission may be purchased for imports to serve native load
• Only BCPS has a NITS contract and is eligible to purchase NE
• unused NE is recalled at xx:40

• fail economic test or failed utilisation and scheduled after xx:30 but before xx:40
• type 1: pro-rata
• type 2: LIFO

Network Integration Transmission Service

Service that allows an electric transmission customer to integrate, plan, economically dispatch and regulate its network reserves in a manner comparable to that in which the Transmission Owner serves Native Load customers

Area Control Error: mathematical formula that calculates load-interchange-generation balance

• - undergenerating
• + overgenerating

ACE= (NAI-NSI) - 10B(Fa-Fs)

Space reserved to serve native load to be used by the LSE in times of emergency

• AREVA determines the proper OTC monitoring limit based on information from:
• MODS, (TSS value from Effective TTC display)
• TSA-PM, (automatically generated number that the AREVA EMS Network Applications derives every couple of minutes)
• and manual entry. (in AREVA OTC Monitor Details display)

TSS is value from MODS

• -MODs is connected to AREVA(EMS) and provides info to AGC
• -AREVA  sends info to PI
• -PI sends info to WIT
• -PI and WIT do not directly communicate to MODs

• BC Hydro will attempt to access OASIS and/or verify if transmission is available (e.g. by checking the ATC Impact Detail or ATC Offering Summary in MODS).  When an OASIS problem occurs, BC Hydro will declare an OASIS outage and backup procedures will go into effect. 
•  
• Checklist
• On OASIS, check Reservations and sort by Updated Time.  If transmission requests are in the queue and not confirmed, this indicates a problem

·         On OASIS, check Sys Data and confirm that the TTCs posted are correct (match MODS).  If it is observed that the TTC has not been updated in a long time, the Transmission Coordinator may be able to update it through MODS. Also check Offerings (blue button) in OASIS to see that ATC offerings are being posted correctly. 

·         Check MODS to determine if Transmission Reservations are being received from other customers.  (Transmission and Scheduling -> Oasis -> TSR -> TSR Summary, and ensure the Customer column is displayed.)  Compare with what is seen in OASIS.
