NERC RC

A) NIA (Net Interchange Actual)
B) NIS (Net Interchange Scheduled)
C) FA (Actual Frequency)
D) FS (Scheduled Frequency)

Rationale: NIS is the scheduled net interchange. ACE compares actual interchange (NIA) to this scheduled value to determine the Balancing Authority's control error. Q2. In the ACE equation, the term 10B(FA-FS) primarily accounts for:

A) Transmission line losses
B) Frequency bias correction
C) Voltage deviation penalty
D) Generator ramp-rate limits Rationale: The term 10 × B × (FA-FS) adjusts ACE for frequency deviation from the scheduled frequency using the frequency bias setting B. Q3. A higher (more negative) frequency bias setting (B) will cause the AGC to:
A) Increase the magnitude of ACE corrections for a given frequency error
B) Decrease the magnitude of ACE corrections for a given frequency error
C) Have no effect on ACE corrections
D) Reverse the direction of ACE corrections Rationale: A more negative B amplifies the frequency-bias component, causing AGC to apply larger corrective actions for the same frequency deviation.

D) Under-frequency load shedding (UFLS) relays Rationale: Primary frequency control is the immediate, automatic response of turbine governors to frequency deviations, governed by their droop settings. Q7. A Balancing Authority's ACE is +200 MW. This indicates:
A) The BA is importing more than scheduled
B) The BA is exporting more than scheduled
C) The BA is on track to meet all performance standards
D) Frequency is above 60.00 Hz Rationale: Positive ACE generally indicates a net export (actual interchange less than scheduled) or frequency bias contribution, depending on the specific equation. Domain 2: Interchange & e-Tagging Q8. In e-Tagging, what is required before a bilateral transaction can be scheduled?
A) Completion of a post-transaction audit
B) Approval from the Reliability Coordinator (RC)
C) Confirmation of a physical line outage

A) A generator exceeds its scheduled MW output
B) The actual net interchange differs from the scheduled net interchange
C) A transmission line is overloaded for more than 15 minutes

B) 90 minutes
C) 2 hours
D) 4 hours Rationale: BAL-002 requires contingency reserve restoration within 90 minutes after the disturbance recovery period. Q16. Common standard time period for station battery to handle outage of AC power to chargers:
A) 4-6 hours
B) 8-12 hours

C) 12-24 hours

A) 2 hours
B) 4 hours
C) 8 hours
D) 24 hours Rationale: Redundant data exchange paths must be restored promptly to ensure operational reliability. Q18. Transition period to a fully functioning backup control facility:
A) 2 hours
B) 4 hours
C) 8 hours
D) 24 hours Rationale: Backup control facilities must be fully operational within 2 hours of activation. Q19. Annual testing of backup control facility must prove to be functional for how long?

Rationale: Blackstart resource operators must receive regular training to ensure effective restoration after a blackout. Q22. The TLR procedure (identifying TLR level and actions to be implemented) needs updating how often?

A) 60 minutes (hourly)
B) 30 minutes
C) 15 minutes
D) 120 minutes Rationale: Transmission Loading Relief procedures require hourly updates to reflect changing system conditions. Q23. Hourly Available Transfer Capability (ATC) for the next 48 hours must be calculated how often?
A) 60 minutes (hourly)
B) 30 minutes
C) 15 minutes
D) 24 hours Rationale: ATC calculations are updated hourly to inform interchange scheduling. Q24. During EEA2/EEA3, the energy deficient entity needs to update the RC how often until the alert is terminated?
A) 60 minutes (hourly)
B) 15 minutes

C) Every 30 minutes
D) At the top of each hour only Rationale: Continuous hourly updates ensure the RC has accurate information during energy emergencies. Q25. How often should BA provide MW-hour meter readings to adjacent BAs?
A) 60 minutes (hourly)

A) 60 minutes
B) 2 hours
C) 4 hours
D) 24 hours Rationale: DOE-417 reports are required within one hour of a significant disturbance. Q27. BA with loss of resources must submit RFI with start time no more than how far beyond the resource loss?

Rationale: Significant firm load loss requires immediate reporting. Q30. Transmission and generator data (including status, output capability, output, phase angle settings, AVR status, etc.) should be updated every:

A) 10 minutes
B) 15 minutes
C) 30 minutes

A) At the top of the hour after the reportable disturbance
B) At the start of the reportable disturbance
C) At the end of the Disturbance Recovery Period
