摘要: |
随着智能电网的发展,信息通信系统与物理电力系统深度融合,虚假数据注入等网络攻击可能会对电网的安全稳定造成严重影响,目前这方面研究已成热点问题。一次成功的虚假数据注入攻击涉及攻击者所掌握资源、攻击区域选择和攻击向量构建。在有限的资源下,根据实际电网运行特征,以攻击节点为中心,构建了单节点攻击区域和多节点攻击区域,一定程度上可缩小攻击范围。基于非线性状态估计模型,分别针对单节点攻击与多节点攻击情形,提出一种掌握局部电网信息下的攻击代价分析方法。最后以IEEE-14系统和IEEE-1354系统为例,分别进行单节点攻击和多节点攻击分析,其结果验证了所提虚假数据注入攻击代价分析方法的有效性。 |

Abstract: |
With the development of smart grid, physical power system has been coupled with cyber and communication system deeper and deeper. Attacks against the cyber and communication system such as False Data Injection (FDI) may cause fatal influences on the security and stability of power system, researches about it has become hot topics at present. One successful FDI attack has to take resources owed by an attacker, the selection of attack area and the building of attack vector into consideration. With limited resources, the single-node and the multi-node attack areas are built around the attacked nodes according to the operation characteristics of the real power system, which can narrow the scale of an attack in some degree. Based on the nonlinear state estimation model, an attack cost analysis method is proposed with limited power system information for the single-node and the multi-node attacks. Lastly, IEEE-14 and IEEE-1354 power systems are applied for the effectiveness of the FDI attack cost analysis proposed by the paper in the situations of the single-node and the multi-node attacks.
