Method and system for demand response in a distribution network

摘要

A method and system for controlling load in a utility distribution network are provided that initiates a shed event for a node in the distribution network by selecting premisess associated with the node that are participating in a demand response program to reduce the load at the node to desired levels. More specifically, the system and method provide for selecting only enough participating premisess associated with the node that are necessary to reduce the load to desired levels.

1. A method for controlling load in a distribution network of customers of a utility, wherein each of the customers has corresponding premises, comprising:
receiving information from the utility for a node in the distribution network demanding power above a predetermined threshold, wherein the information comprises node identification information, a shed amount and a shed duration required to reduce the power demand below the predetermined threshold, and information identifying participating customer premises associated with the node and participating in a load shed program from the utility; estimating a load shed response for the participating customer premises; estimating an adjusted load shed response based on a network connectivity;comparing the adjusted load shed response with the shed amount and the shed duration required to reduce the power demand below the predetermined threshold to determine a node response to the adjusted load shed response;initiating a load shed event when the node response is sufficient to reduce the power demand below the predetermined threshold; andselecting one or more of the participating customer premises for the load shed event based on the node response.
