After a disturbance, what action should a system operator take if re-dispatching generation has no effect on the transmission line?

• A. Contact adjacent BAs
• B. Re-evaluate boundaries
• C. Increase generation output
• D. Schedule maintenance for the line

Answer: (B)

The correct action for a system operator to take after a disturbance, when re-dispatching generation has no effect on the transmission line, is to re-evaluate boundaries. This step is essential because it involves analyzing the operational limits and the current conditions of the transmission system. If the generation adjustments are not alleviating the issues, assessing the operational boundaries can provide insights into whether the limitations of the transmission system itself, or the existing flow of electricity, are causing the problem. This may involve examining load flows, system stability, or other factors that could affect the reliability of the network. Re-evaluating boundaries allows operators to determine if there are any operational inefficiencies or vulnerabilities that could be addressed, such as redistributing loads or modifying processes to improve reliability. It's a proactive approach that helps ensure the power system can continue to operate safely and effectively after a disturbance. The other actions, while relevant in certain contexts, do not directly address the immediate need to understand the situation's boundaries and constraints. Contacting adjacent balancing authorities might provide valuable support or resources but would not resolve the issue at hand. Increasing generation output might exacerbate the problem if the transmission line is already constrained. Scheduling maintenance for the line could be necessary but typically would not be an immediate response
