When does PJM assess selected double contingencies?

• A. Routine operations
• B. Emergency operations
• C. Conservative operations
• D. Maintenance operations

Answer: (C)

PJM assesses selected double contingencies during conservative operations to ensure the reliability and stability of the electrical grid. Conservative operations involve a cautious approach to managing the power system, considering possible risks and uncertainties that could arise during operation. This assessment typically aims to identify potential challenges that may occur if two significant events happen simultaneously, such as the loss of two transmission lines or generating units. It is essential to evaluate how the system would respond under these circumstances to maintain reliable service and prevent widespread outages. While routine operations involve normal functioning of the grid and emergency operations deal with immediate responses to problems, the context of double contingencies fits best within conservative operations, where a careful review of the system’s ability to handle such failures is paramount. Maintenance operations focus on physical upgrades and repairs rather than the operational assessments of contingencies on the transmission network.
