“…The method to maintain balanced PCC voltage and reduce the DC link oscillations is suggested in [313,314], while Guo et al [315] provided the theoretical analysis of the oscillation phenomena under unbalances. A study on the current limitation of the gridconnecting converters is evaluated on a HIL platform in [295], while an advanced NS droop control for the optimum injection of power under two different fault types is discussed in [316]. An improved grid voltage-modulated control with power compensation is explored in [317], while a sequence-decoupled resonant control strategy is proposed in [318] for unbalance mitigation.…”

Unbalance or asymmetry in the distribution network is a well-known power quality issue. In the modern active distribution system, with the increasing penetration of renewables, this phenomenon becomes more pronounced. In the context of microgrids (MGs), several works have been proposed for the management and mitigation of the unbalance, for both the sharing of unbalanced load and maintaining the voltage quality in the islanded mode and for the control of distributed generators in the grid-connected mode during unbalanced conditions. This study comprehensively reviews, summarises, and classifies the various strategies of the unbalance mitigation techniques for the islanded and grid-connected modes of operation for threephase MGs and presents the possible challenges and avenues for future investigations on the topic.
