Typhoon disasters threaten the operational security and stability of Distribution Cyber-Physical Systems (DCPS). Existing studies on enhancing pre-disaster resilience of distribution networks ignore the temporal characteristics of typhoon evolution and the system’s real-time response during disasters, resulting in preventive strategies that fail to meet practical operational requirements. To address this limitation, this study proposes a pre-disaster resilience enhancement scheme for DCPS that integrates the temporal characteristics of typhoon evolution and cyber-physical collaborative control. First, a vulnerability model of DCPS is established, where historical typhoon data are utilized to derive failure probabilities of power lines and communication links, followed by Monte Carlo simulations to generate a set of typical disaster scenarios. Second, considering the coupling between cyber and physical systems, the real-time responses of DCPS under multiple disaster scenarios are simulated to develop a resilience optimization model, from which the optimal pre-disaster reinforcement strategy is derived. Finally, simulation analyses on the PG&E69 distribution system and IEEE 123-node test system demonstrate that the proposed scheme effectively enhances both resilience and cost-effectiveness of DCPS, providing theoretical support for resilience optimization under typhoon disasters. |
