  • Method and system for locally controlling power delivery along a distribution feeder line of an electricity grid
    Patent number: 10044188
    Abstract: A method and a system for controlling grid power distribution by using a controllable real power resource at nodes on the feeder line and a tap changer in a substation on the feeder line by setting a target phasor value at each node that maintains a required power delivery to the real and reactive power resources with a defined acceptable voltage at all nodes with a feeder line loss below an allowable feeder line power loss threshold. The target phasor value is selected to use the substation tap changer less frequently as compared to the reactive power resource to provide voltage management of the feeder line, wherein the power resource is adjusted so that the actual voltage magnitude moves towards the target voltage magnitude at each node.
