To correct for a slow or fast clock, system frequency schedules are offset by: -
answer+/-.02 Hz
What frequency would PJM set to correct for fast-time error? - answer59.98Hz
What frequency would PJM set to correct for slow-time error? - answer60.02Hz
What info is on an instantaneous reserve check? - answersynchronized (regulating and
non-regulating), quick start, secondary and beyond secondary reserves
Generators must provide PJM with a realistic Reactive Capability Curve. This curve
must have no less than __ points, and no more than __ points. - answerNo less than 2
and no more than 8 points
A classic indicator of voltage instability is when system voltages change greatly when...
- answersystem loads change by a small amount
Above the line of a D-curve... - answerLagging (pushing VARs). Generators will be set
there during high-load/low voltage conditions.
Below the line of a D-curve... - answerLeading (absorbing VARs). Generators will be set
there during low load/high voltage conditions.
MWs and MVARs have what kind of relationship? - answerInverse (increase in MW =
decrease in MVARs)
How often do generators need to test reactive power capability? - answerEvery 5 years
The computer hardware and software at each control center shall achieve an availability
level of what for those reliability functions directly affect the successful operation of
PJM? - answer99.95%
, What is EHV? - answerExtra high voltage. Classified as 345kv and above
Any generator that is a PJM generation capacity resource that has an RPM Resource
Commitment: - answer1. Must submit an offer schedule into the DA market even if it is
self-scheduled or unavailable due to outage
2. Generation capacity resources shall submit:
-A schedule of availability for the next seven days
-May submit non-binding offer prices for the days beyond the next Operating Day
What time period is the Market Participant Bid/Offer Period? - answer0800-1100
What time are DA Market results posted? - answer1330
What time period is the re-bid period? - answer1330-1415
What is the maximum for a generation capacity resource offer? - answer$2000/MWh
What is the cap for price-based offers? - answerPrice-based offers will be capped at the
lower of $2000/MWh or the corresponding cost-based offer when costs are above
$1000/MWh
Example:
If a unit's cost is $1500, the price offer can be no higher than $1500
If $800, price offer can be no higher than $1000
If $2200, price offer can be no higher than $2000
