A Coordinated Restoration Method of Hybrid AC/DC Distribution Network for Resilience Enhancement

In recent years, the frequent occurrence of extreme natural disasters has caused huge economic losses, which makes it extremely important to improve resilience distribution networks. With increasing penetration DC sources and loads, urban network is transitioning from AC hybrid AC/DC configuration that can operate in a ring structure. The features flexible interconnections low losses lines break bottleneck traditional restoration methods for networks under disasters, thereby further enhancing Based on interconnection feature lines, this paper proposes topology search strategy with as core realize joint recovery multiple power critical loads. obtained after search, fault model maximizing index established. To ensure generality proposed explore advantages control, transforms objective function complex into mixed integer second-order cone programming (MISOCP) be solved directly. optimal enhancement by solving MISOCP model. numerical results case study validate effectiveness superiority method.
