With the increase of cyberhacking activities, cyber attacks become urgent problems to system security. In this paper, cyber attacks on load frequency control (LFC) is studied. By unifying attack and detection, detection scheme considering specific attack strategies is presented. As for attack scheme design, four attack strategies are systematically analyzed with respect to their mechanism and influence on LFC performance, so that the most effective one is selected as the adopted attack scheme from the viewpoint of hackers. As for attack detection, a novel attack detection approach is proposed by analyzing differences between dynamic features of variables. Multilayer percepton classifier-based approach is used to extract the differences of area control error under attack and in normal situation, thus distinguishing compromised signals from normal ones. Simulation results show the effectiveness of the proposed detection approach.

负载频率控制中考虑网络攻击的新型检测方案设计

随着网络黑客活动的增多,网络攻击已成为系统安全的迫切问题。本文研究了对负载频率控制(LFC)的网络攻击。通过统一攻击和检测,提出了考虑特定攻击策略的检测方案。对于攻击方案的设计,系统地分析了四种攻击策略的机制和对LFC性能的影响,从黑客的角度出发,选择最有效的一种作为采用的攻击方案。对于攻击检测,通过分析变量动态特征之间的差异,提出了一种新颖的攻击检测方法。基于多层感知器分类器的方法用于提取攻击和正常情况下区域控制错误的差异,从而将受损信号与正常信号区分开。仿真结果表明了该方法的有效性。
