Quantum key distribution (QKD) technology can effectively meet the growing information security demands of modern power systems
and its technical development is becoming increasingly mature. However
current research lacks sufficient focus on the resilience of QKD-based quantum power communication networks
especially in terms of systematic studies on the recovery of quantum key supply after QKD network failures. This paper proposes a rapid recovery method for quantum power communication networks that integrates flexible resource allocation with fault repair. First
a resilient quantum power communication network architecture is constructed
incorporating both physical and auxiliary quantum links
to characterize the recovery process of the resilient quantum power communication network involving flexible resources. Second
a mixed-integer linear programming (MILP) model is proposed with the objective of maximizing the recovery value of quantum communication
namely
critical services are rapidly restored by utilizing drones to deploy key resources while simultaneously optimizing the repair sequence of maintenance personnel to gradually recover the quantum key supply capability of the network. Finally
the effectiveness of the proposed method is validated using a modified IEEE 33-bus distribution system. The case study results demonstrate that fully utilizing the flexibility of key resources and the complementarity of the two recovery approaches can significantly enhance the post-disaster recovery efficiency of quantum power communication networks and effectively reduce the risk of load loss in power systems.
