“…These can be modified to enhance performance under unbalanced conditions. Full bridge converter modules are proposed in [45] that can independently inject series voltages into each phase to mitigate unbalances. The four-legged voltage source inverter (VSI) is completely decoupled into three buck-converters through analogue controllers in [46], which allows independent control over the phases.…”

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.

“…The objective of the unbalance compensation or mitigation depends upon the conditions of the MG and the operating mode (islanded or grid‐connected). Unbalance mitigation in islanded MGs [18, 21, 22, 23, 25, 27–32, …”
