What should the Balancing Authority do to handle a voltage drop resulting from a generator trip?

• A. Increase load immediately
• B. Disconnect non-firm load
• C. Take steps to raise voltage without load removal
• D. Only notify the Reliability Coordinator

Answer: (C)

The Balancing Authority is responsible for maintaining the reliability and stability of the power system. When a generator trips offline, it can lead to a voltage drop in the system due to the sudden loss of generation. In this scenario, the most effective response is to take steps to raise the voltage without removing any load. Raising the voltage can be achieved through several methods, such as adjusting transformer taps, engaging voltage support resources like synchronous condensers, or utilizing capacitor banks. These steps help stabilize the system and restore voltage levels while maintaining service to the existing load, which is critical for ensuring that the system remains reliable and avoids unnecessary disruptions. Other approaches, such as increasing load or disconnecting non-firm loads, could exacerbate the situation and lead to further instability in the system. Simply notifying the Reliability Coordinator does not address the immediate issue of voltage drop and does not provide any corrective action to stabilize the system in real-time. Therefore, taking proactive measures to raise voltage is essential for supporting the system's reliability following a generator trip.
