Abstract
A method for determining a power flow in an electrical distribution network () includes determining respective feeder apparent powers of electrical power feeders () connected at a supply node () of the electrical distribution network. The method also includes determining a feeder power factor angle of at least one of the feeders responsive to the feeder apparent powers, a supply node active power, and a supply node reactive power. The method then includes using at least one of the feeder power factor angles for determining a power flow in the electrical distribution network, such as by calculating feeder active and reactive power and using these powers to provide load allocation.
