본문

This paper proposes a control method for grid-connected inverter systems under unbalanced and distorted grid voltage. The

proposed method can reduce the power ripple caused by the unbalanced condition as well as it can compensate the low-order

harmonics of the output currents due to the distortion of grid voltage. To reduce the power ripple, the proposed method replaces

the four conventional PI controllers with two PR controllers in the stationary frame. PR controllers can implement the compensation

of selective harmonic without excessive computational requirements; the use of these controllers simplifies the method. The

simulation results agree well with the theoretical analysis.
