If the frequency bias setting B) The ACE will be a negative value and AGC will increase
is set to a less negative generation
value than the frequency
response of a Balancing
Authority and a
frequency increase is
caused by a sudden loss of
load in an external
balancing area, what will
be the result?
A) The ACE will be zero
and will take no AGC
action
B) The ACE will be a
negative value and AGC
will increase generation
C) The ACE will be a
positive value and AGC
will lower generation
D) This will not affect the ACE

level is starting to decline in
the North West part of the
system. Which of the
following devices should
you, as a Transmission
Operator, be able to
operate, and/or have
another entity operate to
raise the voltage level back
to normal in the North
West part of the system?

D) All answers are correct
Voltage reduction for load A) Distribution system
relief should be made on
the _________.
A) Distribution system
B) Entire Interconnection
simultaneously
C) Tie-lines with other
Balancing Authority Areas
D) Transmission System
Under Frequency Load D) Shedding load prior to generation tripping
Shedding (UFLS) is to
stabilize the imbalance
between
generation and load that has
been created by a system
disturbance. This is
accomplished by _.

B) Voltage reduction on the
distribution system.
C) Shedding all load to arrest
frequency
