考虑蓄意物理攻击与继发故障影响的骨干网架韧性评估方法
A Skeleton Network Resilience Assessment Method Considering the Impact of Deliberate Physical Attacks and Secondary Faults
摘要
Abstract
During the system restoration process after a major power outage,the system has a low resistance to external disturbances.The transmission system is not yet complete,particularly during the network reconstruction phase.If a deliberate physical attack occurs against a power system,it can have a severe impact on system restoration,causing secondary faults impacting the system such as protection failure and disoperation.To quantitatively evaluate the impact of deliberate physical attacks and their secondary faults on the network restoration process,a comprehensive skeleton network resilience assessment method is proposed.First,a model for calculating the system load loss under deliberate physical attacks is proposed based on the attack-defense game model.Second,considering the overload protection malfunction caused by power flow transfer after a disturbance,a set of deliberate physical attacks and secondary fault scenarios are constructed.Finally,based on the forced load loss in the fault scenario set before and after the disturbance,a quantitative assessment method for skeleton network resilience is proposed,and an optimization model of the skeleton network considering active resilience improvement is constructed.An example of an IEEE-57 node system is used to verify the effectiveness of the proposed resilience assessment method.关键词
