ANSWER -Monitoring LMP's
PJM calls for _____________ reserves to recover ace so that tie line schedules are maintained. -
CORRECT ANSWER -PJM calls on synchronized reserves
If not cancelled by PJM, the minimum generation alert expires at the end of the specified
______________. - CORRECT ANSWER -light load period
When PJM declares a hot weather alert, the generation dispatcher should determine if
maintenance can be deferred and notify all generating stations and key personnel. - CORRECT
ANSWER -
During system restoration, the two categories of reserves are dynamic and spinning. -
CORRECT ANSWER -
During system restoration, frequency should be maintained between 59.75 and 61.00 Hertz. -
CORRECT ANSWER -
PJM issues a heavy load voltage schedule. Member companies who own generation facilities
should ensure voltage regulators on generating units are in service & automatic. - CORRECT
ANSWER -
,A unit being dispatched economically by PJM should set its megawatt output based on the unit's
dispatch rate or desired megawatt level. - CORRECT ANSWER -
A fossil steam unit is considered fuel limited when it is not capable of running at its maximum
capacity for the next 72 hours - CORRECT ANSWER -
During system restoration prior to synchronization of a unit, the dispatcher should ensure
sufficient load is available to stabilize unit operation. - CORRECT ANSWER -
A large unit in an external control area near PJM/PJM West trips. The PJM operator will see ace
remain the same, frequency decrease. - CORRECT ANSWER -
LMPs will change when marginal generator output changes - CORRECT ANSWER -
The two control signals sent by the PJM E M S are regulation and dispatch rate (desired MW
output). - CORRECT ANSWER -
An all-call is the one-way communication system used to disseminate information to market
operation centers. - CORRECT ANSWER -
Real time bus prices may be monitored using data viewer. - CORRECT ANSWER -
Not offering an available PJM capacity resource into the day ahead market is a violation of PJMs
two settlement market rules. - CORRECT ANSWER -
A unit that fails to start when scheduled, would be classified as an unplanned outage. -
CORRECT ANSWER -
Maximum Generation Emergency is declared by PJM when generation is required above the
highest incremental economic cost. - CORRECT ANSWER -
, Maintenance outages are permitted when a unit can be held online until the following Monday,
and system reliability is not affected - CORRECT ANSWER -
If PJM ace shows over-generation, actual imports are less than scheduled. - CORRECT
ANSWER -
PJM will request a Supplementary Status Report when a Maximum Generation Emergency Alert
is issued. - CORRECT ANSWER -
If a fossil steam unit has less than 32 hours of fuel at maximum capacity, it should be bid at
maximum emergency. - CORRECT ANSWER -
The loss of a large generation unit on the PJM system can be detected by monitoring frequency
and PJM ace. - CORRECT ANSWER -
A 1000 megawatt unit has tripped in the PJM control area and the PJM ace now indicates under-
generation of 1050 Megawatt. PJM should request 100% synchronized reserves be loaded. -
CORRECT ANSWER -
Alerts are issued in advance of a scheduled load period to allow sufficient time for the generation
dispatcher to prepare for the anticipated capacity shortages - CORRECT ANSWER -
The amount of synchronized reserves must be large enough to cover the loss of the largest single
energy contingency. - CORRECT ANSWER -
When preparing a supplementary status report (SSR), a steam unit that has 30 hours of fuel
remaining. This unit should be reported as a resource limited unit. - CORRECT
ANSWER -
