Method and system for locally controlling power delivery along a distribution feeder of an electricity grid

摘要

A method and system for locally controlling delivery of electrical power along a distribution feeder. For a feeder segment in the distribution feeder the method includes: obtaining an actual voltage magnitude at an upstream node and at a downstream node of the feeder segment, and a real power value at the upstream node; setting a target voltage phasor at the downstream node as a value when a power flow across the feeder segment is maintained, and when equal reactive power is injected at the upstream and downstream nodes that consumes all the reactive power in the feeder segment; and adjusting operation of the at least one controllable reactive power resource so that the actual voltage magnitude at the downstream node moves towards a target voltage magnitude of the target voltage phasor.
