What action should be taken when informed of a slow time error correction that cannot change the scheduled frequency?

• A. Increase Net Interchange Schedule by 20 MWs
• B. Inform the Reliability Coordinator that you cannot participate
• C. Decrease Net Interchange Schedule by 20 MWs
• D. Increase Net Interchange Schedule by 10 MWs

Answer: (A)

When faced with a slow time error correction that cannot change the scheduled frequency, the appropriate action is to increase the Net Interchange Schedule by 20 MWs. This action is based on the principle that a slow time error indicates that the actual system frequency is less than the scheduled frequency. By increasing the Net Interchange Schedule, you are effectively compensating for the shortfall in generation or the overconsumption of load that is causing the frequency to drop. Increasing the Net Interchange Schedule helps to bring additional power into the system, which can assist in stabilizing frequency and ensuring that reliability is maintained. The adjustment reflects a proactive approach to managing system balance, as it acknowledges the existing discrepancy and takes steps to mitigate its effects. The other options do not effectively address the slow time error correction. Informing the Reliability Coordinator of inability to participate does not contribute to resolving the error, while decreasing the Net Interchange Schedule would exacerbate the frequency issue, potentially leading to further reliability challenges. Increasing by just 10 MW is insufficient to correctly respond to the extent of the correction needed. Therefore, the decision to increase by 20 MW is rooted in a proper understanding of system dynamics and reliability management.
