Patent ID: 8788108

Claim:
A method for distributed power management in an electrical power network divided into one or more sections and having plural intelligent electronic devices (IEDs) communicatively connected in a communication network configured for power management function in the one or more sections of the electrical power network, the method comprising: identifying a first IED from the plural IEDs in a section of the electrical power network that issues a load shed command; exchanging power network data between the first IED and one or more IEDs from the plural IEDs in the electrical power network, the data including at least power balance calculation values and an accumulated load value; having the first IED or a second IED of the plural IEDs in the electrical power network identify a power imbalance state in the electrical power network based on the exchanged power network data and generate a load shed trigger in the electrical power network based on at least the accumulated load value as compared with a priority set for an electrical circuit associated with the first IED; having the first IED estimate a power balance condition in the electrical power network based on the load shed trigger generated in the electrical power network; and having the first IED or the second IED perform coordinated power management in the electrical power network based on the estimated power balance condition in the electrical power network.
