Balancing Authority - ANSWER: The entity responsible for maintaining the balance
between the supply and demand of electricity within a specific area.
Meter - ANSWER: A device used to measure the flow of electricity in a power system.
Frequency - ANSWER: The number of times alternating current changes direction per
second, measured in hertz (Hz).
Generators on AGC - ANSWER: Generators that are controlled by Automatic
Generation Control (AGC) to maintain the system frequency within acceptable limits.
ACE reading - ANSWER: The Area Control Error (ACE) reading, which represents the
difference between the actual and scheduled interchange in a Balancing Authority
Area.
Tie-line meter - ANSWER: A meter used to measure the flow of electricity between
two Balancing Authorities.
Exporting - ANSWER: The act of sending electricity from one Balancing Authority to
another.
Total demand indication - ANSWER: The measurement of the total amount of
electricity being consumed within a Balancing Authority.
System Operator - ANSWER: The person responsible for operating and controlling
the power system to ensure its reliability and stability.
Reactive resources - ANSWER: The ability of the power system to provide reactive
power to maintain voltage stability.
Voltage - ANSWER: The electrical potential difference between two points in a
circuit, measured in volts (V).
Load - ANSWER: The amount of electricity being consumed by devices connected to
the power system.
Operating Instruction - ANSWER: A directive given by a System Operator to control
the operation of the power system.
, Operating Plan - ANSWER: A plan developed by a System Operator to guide the
operation of the power system.
Spinning reserve - ANSWER: The amount of generation capacity that is online and
available to respond to changes in demand.
Transmission line - ANSWER: A high-voltage line used to transmit electricity over
long distances in the power system.
Voltage control - ANSWER: The regulation of voltage levels within the power system
to maintain stability and ensure proper operation of equipment.
Generator windings - ANSWER: The coils of wire in a generator that produce the
electrical output.
Islanding conditions - ANSWER: The situation where a portion of the power system
becomes disconnected from the rest of the system, often due to a fault or
disturbance.
Inrush of cold load - ANSWER: The sudden increase in power demand when loads
that have been off for a long time are turned on, causing a temporary surge in
electricity consumption.
MSSC - ANSWER: The Maximum Sustained Secure Capability (MSSC), which
represents the maximum amount of power that a Balancing Area can reliably
support without compromising system stability.
SOL - ANSWER: The System Operating Limit (SOL), which represents the maximum
amount of power that a transmission line or equipment can safely handle without
causing damage or violating operating limits.
LODF - ANSWER: The Line Outage Distribution Factor (LODF), which represents the
impact of a transmission line outage on the power flow of other lines in the system.
EEA - ANSWER: The Energy Emergency Alert (EEA), which represents the level of
emergency in the power system and triggers specific actions to maintain system
reliability.
GIC - ANSWER: The Geomagnetically Induced Currents (GIC), which are electric
currents induced in the power system by geomagnetic disturbances, such as solar
storms.
Real-time assessments - ANSWER: The continuous monitoring and analysis of the
power system to identify any violations, potential problems, or deviations from
normal operating conditions.
