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 three-phase MGs and presents the possible challenges and avenues for future investigations on the topic.

微电网中的不平衡缓解策略

配电网络中的不平衡或不对称是众所周知的电能质量问题。在现代的主动配电系统中,随着可再生能源的普及,这种现象变得更加明显。在微电网(MGs)的背景下,已提出了一些管理和缓解不平衡的工作,既可以共享不平衡的负载,也可以在孤岛模式下保持电压质量,还可以控制电网中的分布式发电机。不平衡条件下的连接模式。这项研究对三相MG的孤岛和并网运行模式的不平衡缓解技术的各种策略进行了全面的回顾,总结和分类,并提出了未来对该主题进行研究的可能的挑战和途径。
