To keep inadvertent interchange down to a minimum, which action is the most effective?

• A. Run one generator on AGC and the rest on manual
• B. Schedule small blocks of megawatts across three consecutive hours
• C. Have correct interchange schedules and accurate tie line metering
• D. Increase the frequency bias setting in the ACE equation

Answer: (C)

Maintaining accurate interchange schedules and precise tie line metering is crucial for minimizing inadvertent interchange, which can happen when there’s a difference between scheduled and actual power flows. When interchange schedules are correctly established, it helps ensure that the amount of electricity expected to flow in and out of a control area aligns closely with what is actually occurring. Accurate tie line metering provides real-time data on the actual flow of electricity across the interconnection points, enabling operators to promptly adjust their operations to stay in sync with scheduled figures. By having this accurate information and adherence to schedules, system operators can make informed decisions to manage power flows more effectively and reduce the chances of any unintended imbalance among interconnected grid systems. This proactive management is key to ensuring reliability and stability in the electrical grid. Other actions, while they may have their benefits, do not directly address the central issue of maintaining accurate and well-coordinated operations in terms of scheduled versus actual power interactions. For instance, running generators with different controls can lead to inconsistency in power generation, while small scheduling blocks could complicate management without ensuring accuracy. Increasing frequency bias settings might adjust responsiveness but does not solve the fundamental issues of scheduling and real-time monitoring that are critical for minimizing inadvertent interchange.
