What is the duration for handling load dump under post-contingency conditions?

The duration for handling load dump under post-contingency conditions is set at 5 minutes. This time frame is critical because it allows the system operators to rapidly respond to an unexpected outage or disturbance.

In the context of power systems, a load dump refers to a sudden loss of load, which can happen due to various reasons, including equipment failures or outages. The 5-minute requirement permits quick adjustments to the generation or demand-side resources to stabilize the system and prevent cascading failures.

Timely actions within this short window are essential for maintaining system reliability and preventing larger disturbances that could lead to grid instability. Therefore, the 5-minute duration reflects the urgency and importance of addressing load dumps effectively to ensure continuous and reliable power supply.
