Abstract

A distributed control node enables total harmonic control. The control node measures current drawn by a load, including harmonics of the primary current. A metering device can generate an energy signature unique to the load including recording a complex current vector for the load in operation identifying the primary current with a real power component and a reactive power component, and identifying the harmonics with a real power component, a reactive power component, and an angular displacement relative to the primary current. The control node can control a noise contribution of the load due to the harmonics as seen at a point of common coupling to reduce noise introduced onto the grid network from the load.
