Interconnections, BAAs, and Inadvertent Interchange Flashcards
What is an interconnection?
An electrically-connected system operating thought the electric grid, regardless of geography.
Name the four interconnections.
1) Eastern
2) Western
3) ERCOT
4) Quebec
Four sub regions of the WECC
- Northwest Power Pool
- Rocky Mountain Power Area
- Arizona-New Mexico-Southern Nevada Power Area
- California-Mexico Power Area
One characteristic of a BAA is:
It has one or more tie lines within the interconnection.
A BAA Tie Line does what?
Measures the energy into and out of a BAA.
Every tie line is?
Metered and telemetered.
The sum of all tie line metering surrounding a BAA is the :
Net Balancing Authority Area Interchange with the Interconnection.
Net Schedule Interchange
NERC term for sum of schedules
Net Actual Interchange
Tie line net metering flow
Inadvertent Exchange = ?
NAI-NSI
Who is responsible for keeping Inadvertent to a If the BAA accurately matches schedules and load, then the accumulated Inadvertent should be ?
minimum
A negative or positive accumulation indicates whether a BAA __________________________ or ___________________.
owes energy to or is owed energy by the Interconnection.
If a Scheduled or Actual Interchange value is changed during the ATF checkout, then __________________________________
one or more BAAs Inadvertent will change by the same amount, ultimately affecting the accumulated Inadvertent impact on the Interconnection.
What is ATEC?
Automatic Time Error Correction
When does ATEC occur?
In Real-Time
