Current Waveform Control of Distributed Generation System for Suppression of Harmonic Voltage and Current on Distribution System.

Abstract

This paper presents the current waveform control of a distributed generation system to suppress harmonic voltage and current on the distribution system. The proposed waveform is composed of the fundamental and harmonics components. The amplitude of each harmonic component is proportional to that of the terminal voltage and the phase is opposite. The characteristics of both the harmonic suppression effect on the distribution system and the capacity of the power converter are examined. The effectiveness of the proposed current waveform control has been verified by experiments.
