随着分布式能源（DER）在配电系统中的深入渗透，潮流模式变得更加多样化，使得配电系统中的过流继电器存在潜在的故障。本文提出了一种数据驱动的方法来设计分布式能源（DER）高渗透率的配电系统中继电器的运行策略。介绍了一种基于支持向量机的中继设置分类器。与传统的过流继电器相比，该方法动作更加准确，误报率更小。它对于改变系统条件（例如负载水平和波动的 DER）也具有鲁棒性。基于 IEEE 123 节点测试馈线的数值研究说明了这种方法的潜力。
With deeper penetration of distributed energy resources (DERs) in the distribution system, the power flow patterns are becoming more diverse, rendering over-current relays in distribution systems with potential malfunctioning. This paper proposes a data-driven approach to design operating strategies of relays in distribution systems with high penetration of distributed energy resources (DERs). A support vector machine-based classifier for the relay setting is introduced. Compared with conventional over-current relays, the proposed method could operate more accurately with smaller false alarm rate. It is also robust to altering system conditions such as load levels and fluctuating DERs. Numerical studies based on the IEEE 123-node test feeder illustrate the potential of this approach.
