In a scenario with a potential IROL violation due to a forced outage, what should the System Operator consider doing first?

In the context of an IROL (Interconnection Reliability Operating Limit) violation resulting from a forced outage, the most important step for the System Operator is to ensure the reliability and stability of the system. Initiating the return of the parallel line with protection is a proactive measure that directly addresses the situation by restoring capacity and maintaining system reliability.

By bringing the parallel line back online while ensuring that the appropriate protections are in place, the operator can mitigate the effects of the outage and help prevent an IROL violation from occurring. This action is critical because it aims to stabilize the system as quickly as possible and can facilitate the resolution of the operational challenges posed by the forced outage.

In considering the other options, being prepared to take corrective actions is certainly a prudent step, but it is more of a reactive stance rather than a proactive solution. Similarly, ensuring that no other lines will trip by taking protective tripping off the line might seem advantageous, but it could also entail additional risk or complications. Calling the Reliability Coordinator (RC) for direction could provide guidance, but it may delay necessary actions that can be taken immediately by the System Operator. Overall, the requirement to act swiftly and decisively in the face of potential reliability issues emphasizes the importance of restoring the parallel line
