网络攻击下电力系统信息安全研究综述

随着信息和通信技术的发展,传统电力系统已经转变成一个具有实时感知、动态控制和信息服务等功能的电力信息物理融合系统。信息系统在优化电力系统功能的同时,网络攻击带来的信息安全问题使电力系统的安稳运行敲响了警钟。文中针对电力信息物理融合系统环境下的网络攻击问题展开讨论,基于攻击目标的差异性对网络攻击进行分类。在研究图论攻击建模方式的基础上,提出网络攻击下实现系统综合安全评估的必要性。最后对电力信息物理融合系统的研究工作进行展望。

A review of information security research in power system under cyber attack

With the development of information and communication technology,the traditional power system has been transformed into a cyber physical power system with real-time perception,dynamic control and information service.While optimizing the function of the power system,the information security problem caused by the cyber-attack has set the alarm for the stable operation of the power system.In this paper,the problem of cyber-attack in the environment of cyber physical power system is discussed,and the cyber-attack is classified based on the difference of attack targets.On the basis of researching the modeling method of graph theory,the necessity of realizing the comprehensive safety assessment of system under cyber-attack is put forward.Finally,the research on the cyber physical power system is prospected.
