Abstract Supply restoration from outages is essential for improving the self-healing ability of active distribution networks (ADNs). Soft open point (SOP) refers to a novel power electronic device installed to replace the traditional tie switch. Under fault situation, the coordination of multiple SOPs can provide voltage support and effectively expand the range of supply restoration. In this paper, a supply restoration method based on the coordination of multiple SOPs is proposed to improve the self-healing ability of ADNs. First, the coordinated service restoration strategy of multiple SOPs is proposed. Then, a self-healing oriented supply restoration method is proposed to restore loads from outages based on multiple SOPs. The contingency set is also established for practical application. Finally, the effectiveness of the proposed supply restoration method is validated on the IEEE 33-node distribution system. It shows that the proposed method can exploit the potential benefits of multiple SOPs and effectively improve the load recovery level of ADNs.

主动配电网中基于多个SOP协调的自愈型供电恢复方法

摘要 停电恢复供电对于提高主动配电网（ADN）的自愈能力至关重要。软开点（SOP）是指一种新型的电力电子设备，用于取代传统的联络开关。在故障情况下，多个SOP的协调可以提供电压支持，有效扩大供电恢复范围。本文提出了一种基于多个SOPs协调的供电恢复方法，以提高ADNs的自愈能力。首先，提出了多个SOP的协同服务恢复策略。然后，提出了一种基于多 SOP 的面向自愈的供电恢复方法来恢复断电负载。应急集也是为实际应用而建立的。最后，提议的供应恢复方法的有效性在 IEEE 33 节点配电系统上得到验证。这表明所提出的方法可以利用多个 SOP 的潜在优势，有效提高 ADN 的负载恢复水平。
