What is 'Inadvertent Interchange' in the context of NERC BAL-006?
Answer: The accumulated difference between actual and scheduled net energy interchange between Balancing Authorities
Inadvertent interchange is the running sum of the differences between actual and scheduled energy exchanges between BAs, which BAL-006 requires entities to track and reduce over time.
Which NERC standard governs the obligations of Transmission Operators regarding real-time monitoring?
Answer: TOP-001
TOP-001 requires Transmission Operators to monitor their transmission systems and operate within applicable reliability limits in real time.
A 'Contingency Reserve' in a Balancing Authority's operating plan is best defined as:
Answer: Capacity held in reserve to replace lost generation following a disturbance
Contingency reserve is generating capacity available to replace power lost following a sudden, unplanned loss of a generator or transmission element.
Under NERC standards, what is the role of the 'Reliability Coordinator' (RC) in real-time operations?
Answer: Maintaining the widest area view of the system and coordinating actions to preserve reliable operation
The RC maintains a wide-area perspective on reliability and has the authority to direct Transmission Operators and Balancing Authorities to take corrective actions.
What does NERC standard INT-006 require regarding interchange schedules?
Answer: Interchange schedules between Balancing Authorities must be tagged and mutually agreed upon before the energy flows
INT-006 requires that interchange transactions be tagged through the e-Tag system and that receiving BAs confirm schedules before energy flows begin.
Which of the following best describes the purpose of NERC's 'Operating Reliability Margin' (ORM)?
Answer: Capacity reserved by a Reliability Coordinator to account for uncertainties in real-time operations
ORM is capacity reserved by the RC to maintain reliability in the face of real-time uncertainties such as load forecast errors and equipment availability.
