论文摘要
安全是电力系统操作中最大的关注点之一。最近，新兴的网络安全威胁电力系统的运营功能引起了广泛的公众关注，因此网络安全脆弱性成为评估网络攻击下的损害运营绩效的新兴话题。在本文中，通过利用系统响应对LFC变量/参数的攻击，可以评估负载频率控制（LFC）系统的网络安全性（LFC）系统的漏洞。两种类型的攻击：1）注射攻击和2）尺度攻击被考虑进行评估。两个反映系统稳定性损害和发电的评估标准用于量化网络攻击下的系统损失。通过基于灵敏度的方法和攻击树模型，对不同LFC组件的脆弱性进行了排名。此外，提出了入侵后网络攻击检测方案。研究了基于典型的分类算法的基于分类的方案并进行比较以识别不同的攻击方案。
Security is one of the biggest concern in power system operation. Recently, the emerging cyber security threats to operational functions of power systems arouse high public attention, and cybersecurity vulnerability thus become an emerging topic to evaluate compromised operational performance under cyber attack. In this paper, vulnerability of cyber security of load frequency control (LFC) system, which is the key component in energy manage system (EMS), is assessed by exploiting the system response to attacks on LFC variables/parameters. Two types of attacks: 1) injection attack and 2) scale attack are considered for evaluation. Two evaluation criteria reflecting the damage on system stability and power generation are used to quantify system loss under cyber attacks. Through a sensitivity-based method and attack tree models, the vulnerability of different LFC components is ranked. In addition, a post-intrusion cyber attack detection scheme is proposed. Classification-based schemes using typical classification algorithms are studied and compared to identify different attack scenarios.
