What action must the System Operator take when power flow reaches System Operating Limits?

• A. Increase power generation at all facilities
• B. Redistribute power flow
• C. Shut down non-essential lines
• D. Alert authorities of the situation

Answer: (B)

When power flow reaches System Operating Limits, the System Operator must take steps to manage and redistribute the power flow effectively. This ensures that the system remains stable and operates within safe parameters. Redistributing power flow helps alleviate potential overloads on specific lines or equipment, thereby enhancing the reliability of the entire grid. This action can involve adjusting generation levels, changing the dispatch of power among resources, or operating transmission infrastructure in a way that balances loads and maintains system integrity. By redistributing power flow, the operator actively manages the risk of cascading failures or outages that could arise from exceeding operational limits. While other actions such as increasing generation, shutting down non-essential lines, or alerting authorities may seem appropriate, they do not directly address the immediate need to adjust and balance the system efficiently. Hence, redistributing power flow is the most strategic and effective response when faced with system operating limits.
