“…The hybrid inverter interface concept is explained in [149], which achieves better VUF if the unbalanced loads are fed by a four-leg inverter than a three-leg one. Souza et al [150] compared three-phase droop and per-phase droop for the performance and stresses on the need to have proper damping in the control. The limits to the fully decentralised droop control methods are discussed in [151].…”

“…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, …”

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 problem of three-phase imbalance in low-voltage distribution networks has become more prominent due to the lack of refinement in management, the impact of single-phase load, unreasonable power grid pattern, and the timeliness of load. The three-phase imbalance of the low-voltage distribution network has an important impact on the power system, which mainly gets reflected by an increase in the transformer loss and temperature rise, reducing transformer output, damaging electrical equipment, and increasing line loss [1][2][3]. In the normal power supply system, the power supply loss of low-voltage distribution network increases, which seriously affects the quality of power supply, which is very uneconomical for power supply companies.…”

In this paper, genetic algorithm and commutation switch based three-phase imbalanced distribution network are studied. A genetic algorithm-based commutation switch three-phase imbalance management strategy was developed, and the three-phase current distribution station area was established. A mathematical model was developed for the multi-objective optimal commutation based on the minimum imbalance degree and the minimum switching times of the low-voltage load online automatic commutation device during the commutation process. Additionally, the real-time online governance control strategies were balanced. Finally, the effectiveness of the proposed method was verified using simulation studies.
