The thumb-rule for load shedding in relation to frequency change is significant for maintaining system stability and reliability in power transmission operations. When the demand for electricity exceeds the supply, the frequency of the grid begins to drop. To offset this imbalance, load shedding is implemented, where a specific percentage of the load is intentionally disconnected from the system to restore frequency to acceptable levels.

The correct answer indicates that a load shedding of 6%-10% typically results in a 1 Hz increase in frequency. This range is widely recognized in electric grid operations because it strikes a balance where the amount of load removed can effectively help stabilize the system without over-shedding, which could lead to other operational challenges. Understanding this relationship helps operators make informed decisions about how much load to shed in response to frequency drops, ensuring that the overall system remains stable and that generation can be aligned with demand effectively.

This thumb-rule varies based on system conditions, but the stated range aligns well with operational practices observed in many power systems. By adhering to this guideline, operators can quickly determine the necessary actions needed to stabilize frequency during grid disturbances.
