After a frequency recovery, what is the total load a Transmission Operator must restore manually if the system frequency falls and subsequently returns to normal?

• A. 45 MW
• B. 80 MW
• C. 65 MW
• D. 25 MW

Answer: (A)

The correct total load the Transmission Operator must restore manually after a frequency recovery is 45 MW because this figure typically represents the difference between the load that was lost during the frequency drop and the load that can be automatically restored by generators and other sources. During a frequency disturbance, loads may be shed to maintain system stability. Once the frequency recovers, not all of these loads can be automatically restored by the system. The manual restoration of loads is essential to bring the system back to its normal operational state while ensuring that the frequency remains stable. In this context, the chosen total of 45 MW signifies the specific amount of load that must be actively managed and reintroduced into the system after the initial disturbances have been corrected and the frequency is back within acceptable operational limits. This amount typically accounts for the load that was disconnected to protect the grid from further frequency dips and ensures the system's reliability moving forward.
