Conclusion:In this paper, the detailed control of grid-interfacing inverters supporting negative-sequence voltage correction has beenpresented from basic principle. Based on the voltage unbalance factor and the system’s capacity, the inv erter absorbs a smallamount of negative-sequence current from the grid, thereby correcting the negative sequence voltage. It has been shown that agrid-interfacing inverter, in addition to its normal operation, can help to decrease the negative-sequence voltage at the PoC. Byusing many of these modules, a substantial improvement is possible. Furthermore, the improved multi -variable filter can filterout positive- and negative-sequence components accurately in case of unbalanced/distorted situations in the stationary frame.The functionality and control scheme are verified by simulation results are shown.VII.
