Active network management

摘要

A method for defining one or more ANM zones in an electricity network that has at least one energy producing/consuming device that has an output that has to be regulated. The method comprises determining the maximum power and/or current transmittable to or from a node or branch in the network at which an energy producing/consuming device that has to be regulated is to be added; determining the maximum capacity of power and/or current transmittable through that node or branch; and defining a zone (zone 1, zone 2) including the node or branch and regulated energy producing/consuming device that requires to be actively managed, in the event that the maximum power and/or current transmittable to the node or branch exceeds the maximum capacity of power and/or current transmittable through it.

1. A method for controlling a regulated group of energy producing/consuming devices in an electricity network, the method comprising:
applying one or more fixed or variable sequential power flow trigger levels to disconnect individual regulated energy producing/consuming devices in the event that the sequential power flow trigger level is exceeded, wherein the regulated energy producing/consuming devices are individually and sequentially disconnected from the network; applying one or more reset power flow trigger levels which when breached reset the regulated energy producing/consuming devices to restart producing/consuming power, the reset power flow trigger level being lower than the sequential power flow trigger level; applying one or more trim power flow trigger levels, which when breached causes the regulated energy producing/consuming devices to reduce producing/consuming power; and monitoring power flow to determine when any of the one or more of the sequential power flow trigger levels, the trim power flow trigger levels, and the reset power flow levels are breached.
