This paper proposes a compensation method for the 2ⁿᵈ -order harmonic of single-phase grid-connected wind power generation systems. Theoretically, a single-phase grid-connected inverter system has no choice but to cause the 2ⁿᵈ -order harmonic to DC-link voltage. The reference active current is affected by the DC-link voltage. The output current from the reference active current is distorted by the 1ˢᵗ and 3ʳᵈ -order harmonic. The proposed method can compensate, conveniently, the reference active current with the 2ⁿᵈ -order harmonic. To reduce the 2ⁿᵈ -order ripple in the reference active current, proposed method takes a PR controller as a feed-forward compensator. PR controllers can implement selective harmonic compensation without excessive computational requirements; the use of these controllers simplifies the method. Both the simulation and experimental results agree well with the theoretical analysis.
