Predictive Load Shedding calculates the minimum required MW to be shed for each subsystem according to the type and location of the disturbance, actual operating generation, spin reserve, loading, configuration, load distribution, and priority. Predictive Load Shedding then selects the best combination of loads that will satisfy this requirement.
All of this is executed instantaneously (no delay) after a disturbance occurs in the system for transient events or after user-defined time delay for steady-state overload conditions.
