Reactive equipment is available C. Reliability stays at acceptable levels D. Synchronous condensers are off the line - ANS-C. Reliability stays at acceptable levels Control Area A is generating and sending Control Area B a schedule. Both control areas should verify all of the following EXCEPT: A. Magnitude (MW) B. Ramp rate C. Price D. Start/stop times - ANS-C. Price The AGC control mode that is normally used for system operation is: A. Flat Tie Mode B. Flat Frequency Mode C. Frequency Bias Mode D. Tie Line Bias Mode - ANS-D. Tie Line Bias Mode There has been a wide-area disturbance. The transfers through the system have increased and there is a possibility that loss of one major tie line would cause corresponding loading and voltage deviations. Having system resources available, the security coordinator should:
