Abstract

This article presents a methodology for the estimation of harmonic current sources in electrical power systems based on the use of Independent Component Analysis (ICA). Through complex harmonic voltage phasors measured by PMUs (Phasor Measurement Units), harmonic profiles can be observed and considered for source estimation. An algorithm based on a moving average filter is responsible for decoupling the fast and slow variations of the harmonic profiles that are used by ICA for the estimation of current sources, tracking them throughout the day. Computer simulations in the IEEE 14-Bus system are performed to validate the proposed methodology.
