Abstract

In order to improve effectiveness of damage resilience assessment of urban power networks under threat of intentional attacks, a performance response function (PRF) method was used in combination with strategy game model of attacker and defender to develop a damage resilience assessment method and procedure. At the same time, a new type of performance response function was designed by integrating power flow analysis to make resilience evaluation result better meet actual functional requirements of power network. Finally, with a power network in a city of China as an example, strategy game model was employed to solve Nash equilibrium strategies of attacker and defender, and damage resilience under different recovery conditions was evaluated. The results show that Nash equilibrium strategy is the most possible attack and defend strategy for both sides, and damage resilience of urban power network is jointly controlled by recovery resources and recovery budget. While the former decides recovery speed, the latter determines recovery level. © 2021 China Safety Science Journal. All rights reserved.
