摘　　要：虚假数据注入攻击是威胁电力系统安全稳定运行的重要因素之一,研究攻击者针对电力系统的网络攻击方法,能为改进系统防御措施提供决策依据。文中基于高压直流换流站运行特性与交直流耦合特性,提出了面向交直流混联系统的虚假数据注入攻击方法。首先,分析了交直流混联系统状态估计的基本原理;然后,提出了针对交直流混联系统的攻击策略,构建了攻击模型;最后,以改进的IEEE 30节点系统为例进行仿真验证。算例结果表明针对交直流混联系统的虚假数据注入攻击能够绕过不良数据检测算法,破坏系统的安全稳定运行,验证了所提模型和方法的有效性。False data injection attack is one of the important factors that threaten the safe and stable operation of power systems.The research on the methods of the attack against power systems can provide decision-making basis for the improvement of power system defense measures.Considering the operation characteristics of high voltage direct current(HVDC)converter station and AC-DC coupling characteristics,a false data injection attack method for AC-DC hybrid system is proposed.Firstly,the basic principle of state estimation of AC-DC hybrid systems is analyzed.Secondly,the attack strategy in AC-DC hybrid systems is proposed,and the attack model is constructed.Finally,the improved IEEE 30-bus system is taken as an example for simulation verification.The results show that the false data injection attack against AC-DC hybrid system can bypass the bad data detection algorithm and endanger the safe and stable operation of the system,which verifies the effectiveness of the proposed model and method.
