In a system restoration process, what is typically the highest priority after communication verification?

1. Restore under-frequency load

2. Manage thermal units' outputs

3. Bringing online additional generation

4. Stabilize system frequency

The correct answer is: Bringing online additional generation

In a system restoration process, the highest priority after communication verification is typically to bring online additional generation. This step is crucial because, after a disruption, the system may experience a significant imbalance between the supply and demand for electricity. By bringing additional generation online, the system can ensure that it has enough power to meet the demand as loads ramp back up, thus stabilizing the overall system. Once generation capacity is increased, it helps to address any potential deficits that might threaten system reliability. This is particularly important during restoration when loads are reconnected progressively—focusing on bringing additional generation online can effectively prevent widespread outages and maintain system integrity. Other priorities, while important, focus on specific aspects of system stability. For instance, restoring under-frequency load is significant, but it often occurs after sufficient generation is online to prevent additional frequency issues. Similarly, managing thermal units' outputs and stabilizing system frequency will also take place, but they typically follow the immediate need to ensure there is adequate generation to support the system during restoration.
