BAL-002 Flashcards
(24 cards)
What is the purpose of BAL-002?
Ensure the Balancing Authority or Reserve Sharing Group balances resources and demand. Returns its ACE to defined values following a Reportable Balancing Contingency Event.
Who does BAL-002 apply to?
Balancing Authorities and Reserve Sharing Groups
BAL-002 requires each Balancing Authority or Reserve Sharing Group to:
Develop and implement an Operating Process as part of its Operating plan
AND
Determine its Most Severe Single Contingency
Responsible Entity must have available Contingency Reserve ___ the MSCC for maintaining reliability.
equal to or greater than
The Operating Process is required to be reviewed and maintained ___.
annually
NERC requires a Balancing Authority or Reserve Sharing Group experiencing a Reportable Event return their ACE to acceptable parameters within ___ period.
15 minute
What is the time limit for a Contingency Event Recovery Period?
15 minutes
If the Responsible Entity’s ACE was positive prior to a contingency event, the ACE must only be returned to ___ within the 15 minute recovery period.
zero
If the Responsible Entity’s ACE was negative prior to a contingency event, the ACE must only be returned to ___ within the 15 minute recovery period.
the that initial value
Each Balancing Authority or Reserve Sharing Group is required to have Contingency Reserve equal to or greater than the ___.
Most Severe Single Contingency (MSSC)
If a subsequent event occurs during the 15 minute recovery period, the required ACE recovery is ___.
reduced by the MW loss amount of the subsequent event
Reportable Balancing Contingency Event
Event occurring within a one minute interval of an initial sudden decline in ACE that results in a loss of MW output less than or equal to 80% of the MSSC.
Each Interconnection has its own minimum amount of MW loss that counts as a reportable event. The Eastern Interconnect has ___, ERCOT has ___, and both Western and Quebec Interconnect have ___.
900MW
800MW
500MW
Multiple Balancing Contingency Events occurring within ___ of each other count as a single contingency.
one minute
If the combined loss of 2 Balancing Contingency Events occurring within ___ of each other falls within the ___ of the MSSC, the ___ Event Recovery Period applies to the event.
one minute
80-100%
15 minute
Exceptions to 15 minute recovery time period involve ___ situations.
Energy Emergency Alert
Responsible Entity must complete NERC ___ for each Reportable Event which calculates the percent recovery for that event.
CR Form 1
The minimum compliance for NERC Disturbance Control Standard (DCS) is?
100% of all reportable disturbances
What are Operating Reserves?
Capability above firm system demand that provides for regulation, load forecasting error, and equipment forced outages.
Operating Reserves consist of ___ Reserve and ___ Reserve.
Operating
Contingency
What is Regulating Reserve?
Reserve Capacity responsive to Automatic Generation Control (AGC) and provides adequate margin of regulation for maintaining ACE. Must be spinning reserves.
What are Contingency Reserves?
Additional capacity used during abnormal system conditions for responding to loss of generation contingencies.
What are spinning reserves?
Unloaded generation synchronized to the system and fully available to serve additional demand
Contingency Reserves can be ___ reserve, ___, and ___.
spinning, quick start generation, controllable load
