摘　　要：面对DG大规模分散接入配电网的情形,传统的集中控制策略有着计算量庞大、通信延迟高、控制效率低等问题,分布式发电群调群控技术能显著改善上述问题,但目前在集群划分方法与集群划分算法上的研究仍有缺陷,故充分考虑电气距离、调控难度和调节成本等因素,提出一种基于模糊聚类算法的集群划分策略,将不同量纲的划分指标归一集合,并经某地10 kV馈线系统验证该策略的可行性和有效性。In the face of DG′s large-scale decentralized access to the distribution network,the traditional centralized control strategy has problems such as large calculation burden,high communication delay and low control efficiency.Distributed generation clustered regulation and clustered control technology can significantly improve the aforementioned problems,but the current research on cluster division method and cluster division algorithm is still insufficient.Considering adequately the electrical distance,difficulty of regulation and adjustment cost,this paper proposes a cluster division strategy based on fuzzy clustering algorithm,which integrates the division indicators of different dimensional dimensions.The practical application to an exemplary 10 kV feeder system verifies the feasibility and effectiveness of the proposed strategy.
