基于多目标双层规划的智能电网虚假数据注入攻击研究

Research on False Data Injection Attack of Smart Grid Based on Multi-objective Bi-level Programming

相对于传统电网,智能电网引入了先进的信息通信技术能显著提高企业生产效率和电力数据处理效率,但由于传统状态估计的漏洞,智能电网易受到虚假数据注入的攻击。现有的研究仅追求电力系统运营成本的最大化或攻击资源的最小化,没有考虑两者之间的均衡。基于此,本文考虑建立智能电网虚假数据注入攻击双层多目标规划模型,其中多目标表示电力系统运营成本与攻击成本之间的均衡,并结合IEEE 14总线算例进行分析,针对攻击者不同的攻击倾向给出了相应的虚假数据注入攻击策略。

Compared with the traditional power grids,the smart grid introduces advanced information and communication technologies,which can significantly improve production efficiency and power data processing efficiency of enterprises.However,due to the loopholes in traditional state estimation,smart grid is vulnerable to false data injection attacks.Existing researches only pursue the maximization of power system operation cost or the minimization of attack resources,and do not consider the balance between them.Based on this,this paper considers to establish a multi-objective bi-levelplanning model for smart grid false data injection attacks,where multi-objective represents the balance between the power system operating costs and the attack costs,then combined with the numerical results based on IEEE 14 bus example,the corresponding strategy of false data injection attack is given according to the different attack tendency of the attacker.
