Restoration strategy for power distribution networks considering the response to cyber attacks
TL;DR
A model for the cyber-physical coordinated restoration of power distribution networks considering communication-physical coupling is established to optimize the restoration process and mitigate the impact of the attack.
Abstract
With the increasing frequency of extreme weather events and cyber attacks, the secure operation of power distribution networks faces severe challenges. Man-in-the-Middle attack is cyber attack method in which attacker intercepts and alters the communication data, potentially leading to power outages. This paper proposes a comprehensive strategy to address this attacks during the restoration process of power distribution networks. Firstly, the principles and target objects of attacks are analyzed, and their propagation mechanisms within power distribution networks are studied. Further, a model for the cyber-physical coordinated restoration of power distribution networks considering communication-physical coupling is established to optimize the restoration process and mitigate the impact of the attack. Finally, the effectiveness of the proposed method is validated through simulation experiments on the IEEE-33 bus power system.
