摘要: 为提升蓄意攻击威胁下城市电力网络毁伤韧性评估的有效性,采用性能时程响应函数(PRF)法,结合攻防双方策略博弈模型,建立蓄意攻击下城市电力网络毁伤韧性评估方法及流程;同时,融合电力潮流分析设计新型性能PRF,使韧性评估结果更符合电力网络实际功能需求;以我国某市电力网络为例,依托策略博弈模型求解出纳什均衡状态下攻防双方策略,并评估不同恢复条件下该电力网络毁伤韧性。研究结果表明:纳什均衡策略为攻防双方最有可能采取的攻击和防护策略,城市电力网络的毁伤韧性受恢复资源和恢复预算2个条件共同控制,恢复资源决定网络的恢复速度,恢复预算决定网络的恢复程度。

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.

Key words: intentional attack, urban power network, damage resilience assessment, strategy game model, performance response function(PRF), recovery resource
