Abstract
A system for managing an electric power delivery system is disclosed that includes a set of remote intelligent electronic devices (IEDs) and a central IED. The remote IEDs may be configured to obtain information related to rotor angles, operating frequencies, rate of change of frequency, rotating inertia, and power consumption levels of loads and generators included in the electric power delivery system. The central IED may communicate with the remote IEDs to determine which loads and generators are associated with a sub-grid of the electric power delivery system and whether to disconnected certain loads or generators. Based on this determination, the central IED may direct the remote IEDs to disconnect loads or generators from the electric power delivery system, or to rapidly increase or decrease generator output as appropriate.
