Automatic Generation Control: Balancing Power Systems in Disturbances

What is used to help balance a system after it separates from the Interconnection during a disturbance?

Final Answer: option b) Automatic generation control

Answer:

Automatic generation control because it is specifically designed to help balance a power system during disturbances by regulating the output of generators to match load demand and maintain grid stability.

Automatic generation control (AGC), represented by option b, is used to help balance a system after it separates from the Interconnection during a disturbance. AGC is a crucial component of power grid management, and its primary function is to maintain the balance between electricity generation and consumption in real-time.

During disturbances or sudden changes in power demand or supply, the power grid needs to adjust rapidly to maintain stability. AGC continuously monitors and adjusts the output of power generators to match the load demand. It does so by controlling the power output of generators, ensuring that the frequency and voltage of the grid remain within acceptable limits.

In contrast, the other options mentioned (GPS, satellite dishes, and traffic lights) are not directly related to power grid stability and control. GPS is a global positioning system, satellite dishes are used for communication and broadcasting, and traffic lights are used for traffic management.
