Interconnection reliability operationsand coordination
IRO - correct answer ✔✔Interconnection reliability operations
The reliability coordinator is responsible for - correct answer ✔✔the reliable operation of the bulk
electric system
IRO -001 - correct answer ✔✔authority
IRO - 003 - correct answer ✔✔Wide area view
The RC shall know the current status of all _______ in their whose failure, degradation or disconnection
could result in a system operating limit or an interconnection reliability operating limit violation - correct
answer ✔✔
Since events in one part of the system can influence operations in all other parts of the system, the RC is
required to monitor and determine any potential SOL and IROL violations - correct answer ✔✔True
Once a Reliability Coordinator issues a directive to preserve the integrity and reliability of the Bulk
Electric System, actions shall be taken without delay, but no longer than ________. - correct answer
✔✔30 minutes
Reliability Coordinator shall initiate control actions or emergency procedures to relieve the violation
without delay and no longer than ___________. - correct answer ✔✔30 minutes
___________ have the duty to continuously assess transmission reliability and coordinate emergency
operations among the operating entities within the region and across the regional boundaries. - correct
answer ✔✔Reliability Coordinators
,A portion of a Reliability Coordinator Area is experiencing low voltage, what directives should the
Reliability Coordinator give? - correct answer ✔✔Lower transfers across area and increase generation in
area with low voltage
Low voltage is a result of reactive power and losses associated with transferring power to load areas.
Increasing generation in the area with low voltage reduces losses associated with transferring power.
At any time, regardless of prior planned or unplanned events, the Reliability Coordinator should be able
to determine any potential ______________ violations within its Reliability Coordinator Area. - correct
answer ✔✔System Operating Limits (SOL) & Interconnection Reliability Operating Limits (IROL)
The _______ as defined by NERC is the electrical generation resources, transmission lines,
interconnections with neighboring systems, and associated equipment, generally operated at voltages of
100 kilovolts or higher. - correct answer ✔✔Bulk Electric System
Each Reliability Coordinator shall have adequate analysis tools, such as state estimation, contingency
analysis capabilities and ________ to monitor the Bulk Electric System. - correct answer ✔✔wide-area
overview displays
Wide-Area view is required therefore, each Reliability Coordinator shall have adequate analysis tools;
such as, state estimation, pre- and post-contingency analysis capabilities (thermal, stability, and voltage),
and wide-area overview displays.
This is stated in the NERC Standard IRO-002 explicitly and applied in the NERC Standard IRO-003 as the
RC shall monitor a wide area view within its Reliability Coordinator Area and that of neighboring
Reliability Coordinators.
Reliability Coordinators that delegate tasks to other entities shall have formal operating _________ with
each entity to which tasks are delegated. - correct answer ✔✔agreements
If Reliability Coordinator tasks are delegated to other entities, the Reliability Coordinator shall verify that
these tasks are carried out by ___________ operating personnel. - correct answer ✔✔NERC certified
, Reliability Coordinators shall have clear, comprehensive coordination agreements with adjacent
Reliability Coordinators to ensure that System Operating Limit or Interconnection Reliability Operating
Limit violation mitigation requiring actions in adjacent Reliability Coordinator Areas are __________. -
correct answer ✔✔coordinated
Once a Reliability Coordinator issues a directive to preserve the integrity and reliability of the Bulk
Electric System, actions shall be taken without delay, but no longer than ________. - correct answer
✔✔30 minutes
Reliability Coordinators will have authority to take appropriate emergency actions to mitigate and
maintain the reliable operation of the bulk power transmission system, up to and including
_______________. - correct answer ✔✔shedding load
A portion of a Reliability Coordinator Area is experiencing low voltage, what directives should the
Reliability Coordinator give? - correct answer ✔✔Lower transfers across area and increase generation in
area with low voltage
___________ have the duty to continuously assess transmission reliability and coordinate emergency
operations among the operating entities within the region and across the regional boundaries. - correct
answer ✔✔Reliability Coordinators
Which of the following are required tasks of the Reliability Coordinator for its Reliability Coordinator
Area? - correct answer ✔✔Monitor all Bulk Electric System facilities
Determine potential SOL violations
Determine potential IROL violations
The ____________ function was established to provide entities with a "big picture" view of the system. -
correct answer ✔✔Reliability Coordinator
Each Reliability Coordinator shall have adequate analysis tools, such as state estimation, contingency
analysis capabilities and ________ to monitor the Bulk Electric System. - correct answer ✔✔wide-area
overview displays
