This paper presents a theoretical discussion on a combined-compensation control method and its stability on harmonic resonance for grid-connected converters. The interaction between the grid impedance and the grid-connected converter potentially creates harmonic resonance. The compensation control with a combination of a digital filter and a virtual impedance is an effective solution for this problem. The theoretical analysis developed in this study reveals that the proper use of the two control schemes enhances the availability of grid-connected converters. Simulated results obtained from a three-phase high-power converter system verify this analysis.
