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.
