A dynamic schedule tagged for 100 MW must change by what minimum amount for an update?

In the context of dynamic scheduling within the North American Electric Reliability Corporation (NERC) framework, the concept behind the minimum change requirement for a dynamic schedule relates to ensuring proper operational efficiency and system reliability.

The correct answer indicates that a dynamic schedule tagged for 100 MW must change by a minimum of 26 MW for an update. This threshold is important because it aligns with the operational guidelines established to minimize the number of adjustments made to schedules. Frequent small changes could lead to unnecessary complexity and degradation in the accuracy of system operations. By setting a minimum threshold for updates, the reliability and stability of the grid are enhanced, as larger adjustments can be managed more effectively.

The selection of 26 MW is based on these guidelines and reflects a balance between operational effectiveness and the technical constraints of real-time system management. Understanding the rationale behind these values helps operators and planners maintain a reliable power grid while adhering to regulatory standards.
