提出了一种孤岛微网电压不平衡补偿的分布式协调控制方案。通过让各分布式发电机（DG）共同分担补偿工作，可以补偿敏感负荷母线（SLB）上的不平衡电压。首次提出了补偿贡献水平的概念，以反映各区域DG的补偿能力。为每个本地DG设计了一个由通信层和补偿层组成的两层二次补偿结构。提出了一种基于有限时间平均一致性和新开发的图发现算法的分布式信息共享与交换策略。该策略不需要将整个系统结构作为先验知识，能够自动检测出系统结构。该方案不仅实现了与集中式方案相似的VUC性能，而且具有通信容错和即插即用等优点。案例研究，包括通信故障，CL的变化，和DG即插即用进行了讨论和测试，以验证所提出的方法。
This paper presents a distributed cooperative control scheme for voltage unbalance compensation (VUC) in an islanded microgrid (MG). By letting each distributed generator (DG) share the compensation effort cooperatively, unbalanced voltage in sensitive load bus (SLB) can be compensated. The concept of contribution level (CL) for compensation is first proposed for each local DG to indicate its compensation ability. A two-layer secondary compensation architecture consisting of a communication layer and a compensation layer is designed for each local DG. A totally distributed strategy involving information sharing and exchange is proposed, which is based on finite-time average consensus and newly developed graph discovery algorithm. This strategy does not require the whole system structure as a prior and can detect the structure automatically. The proposed scheme not only achieves similar VUC performance to the centralized one, but also brings some advantages, such as communication fault tolerance and plug-and-play property. Case studies including communication failure, CL variation, and DG plug-and-play are discussed and tested to validate the proposed method.
