Abstract

See full text

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 operating frequencies and power consumption levels loads included in the electric power delivery system. The central IED may communicate with the remote IEDs to determine which loads are associated with a sub-grid of the electric power delivery system and whether to disconnected certain loads. Based on this determination, the central IED may direct the remote IEDs to disconnect loads from the electric power delivery system.
