What can prevent imminent separation from the interconnection?

Load shedding is an effective measure to prevent imminent separation from the interconnection because it involves the intentional reduction of electrical load on the system. When there is an imbalance between supply and demand, such as during an emergency or system disturbance, shedding load can help stabilize the system. By disconnecting certain loads, the overall demand on the electrical grid is reduced, allowing the generation capacity to more closely match the remaining load. This action can effectively alleviate the stress on the grid and prevent cascading failures that could lead to separation.

In situations where the system is at risk of separating, quick and controlled load shedding can stabilize frequency and voltage levels, thus preserving the integrity of the power network and preventing a blackout or major disruptions. This is essential in maintaining the overall reliability and security of the electrical grid.
