Control of Grid-Following Inverters Under Unbalanced Grid Conditions [PDF]
IEEE Transactions on Energy Conversion, 2020 This paper proposes a new control scheme to eliminate the 3rd harmonic in the output currents of grid-following inverters under unbalanced grid conditions. Unbalanced grids adversely affect the performance of grid-following inverters due to the oscillations appearing on the DC-link voltage with a frequency twice the line frequency.
