This paper presents inverter control strategies to compensate for the distorting effects of unbalanced and nonlinear loads in 4-leg inverter-fed power systems. Synchronous frame controllers are utilized at selected frequencies to eliminate positive and negative sequence distortion.Additionally, stationary frame controllers are employed to attenuate zero sequence distortion due to non-zero neutral currents. Combined with fundamental control this strategy is demonstrated to achieve a high level of performance under challenging loading conditions.

An algorithm for compensating island network voltage unsymmetridty with a DTC-modulation based scalar controlled power conditioning system is introduced and experimentally veriried. The proposed method consists two separate stages where f i t the unsymmetricity is detected and then the compensating negative sequence system is calculated. Experimental results show that the proposed method fuUy compensates the voltage nnsymmetricity resultlug from unbalanced load. Both the magnitude and the phase angle unsymmetricity are compensated.
