Question 7

A CPS1 violation is an indication that:

Answer 7

A BA’s ACE is hindering frequency

Question 8

1. 25 mile, overhead transmission line
2. 10 mile, overhead transmission line
3. 25 mile, underground transmission cable

Question 9

Who must have plans for operator controlled manual load shedding to respond to real-time emergencies?

Answer 9

Transmission Operators and Balancing Authorities

Question 10

During a system emergency, the System Operator can direct other Transmission Operators and Balancing Authorities to violate which limit?

Answer 10

None. Equipment parameters should be maintained within their established limits

Answer 12

Reliability Coordinator and Balancing Authority

Question 13

If a Balancing Authority is unable to purchase capacity or energy to meet its demand and reserve requirements on a day-ahead basis, which entity or entities, is it expected to notify?

Answer 13

Its Reliability Coordinator and Balancing Authorities

Question 14

If a transmission Operator or Balancing Authority is unable to restore Real and/or Reactive Power Balance, they must request emergency assistance from the Reliability Coordinator. If Operating Reserves are not available, corrective action need to include:

Answer 14

implement manual load shedding

Question 15
