Systems and Methods for Under-Frequency Blackout Protection
First Claim
1. A system for managing an electric power delivery system comprising:
- a plurality of intelligent electronic devices (IEDs), each IED of the plurality of IEDs being communicatively coupled with a load, wherein each IED of the plurality of IEDs is configured to obtain system information related to an operating frequency of a load and power consumption of a load, and wherein each IED of the plurality of IEDs is configured to selectively disconnect a load from the electric power delivery system; and
a central IED communicatively coupled with the plurality of IEDs, the central IED being configured to receive the system information from the plurality of IEDs and, based on the system information, determine which loads are associated with a sub-grid of the electric power delivery system and whether to disconnect one or more loads associated with the sub-grid from the electric power delivery system.

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 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.

11. A method for managing and electric power delivery system using a central intelligent electronic device (IED) comprising:
-
receiving, at the central IED from a plurality of IEDs, each IED of the plurality of IEDs being communicatively coupled with a load, system information related to the operating frequencies of the loads and the power consumption of the loads; determining, by the central IED, which loads are associated with a sub-grid of the electric power delivery system based on the system information; and determining, by the central IED, whether to disconnect one or more loads associated with the sub-grid from the electric power delivery system. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An intelligent electronic device (IED) associated with an electric power delivery system, the IED comprising:
-
an interface configured to receive system information from a plurality of remote IEDs, the system information relating to the operating frequencies and power consumptions of loads associated with the plurality of remote IEDs; a processor communicatively coupled to the interface; a computer-readable storage medium communicatively coupled to the processor, the computer-readable storage medium storing instructions that when executed by the processor cause the processor to determine, based on the system information, which loads are associated with a sub-grid of the electric power delivery system and whether to disconnect one or more loads associated with the sub-grid from the electric power delivery system. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
