With the development of distributed networks, the remote controllability of the distributed energy objects and the vulnerability of user-side information security protection measures make distributed energy objects extremely vulnerable to malicious control by attackers. Hence, the large-scale loads may produce abnormal operation performance, such as load casting/dropping synchronously or frequent and synchronous casting and dropping, and hence, it can threaten the security and stable operation of the distribution networks. First, we analyze the security threats faced by industrial controllable load, civil controllable load, and the gains and losses of attacks on the distribution networks. Considering the factors of cyber attacks, we propose a control model and cyber attack model in active distribution networks (ADNs). And, three types of attacks that the target suffered are defined on the basis of “on” and “off” modes for control. Then, the controllable load was maliciously controlled as the research object, and a suitable scenario is selected. The impact of malicious control of the controllable load on the power supply reliability and power quality of the distribution networks are simulated and analyzed, and risk consequences for different types of attacks are provided.

恶意攻击下具有可控大规模负载的主动配电网安全风险分析

随着分布式网络的发展，分布式能源对象的远程可控性以及用户端信息安全保护措施的脆弱性使得分布式能源对象极易受到攻击者的恶意控制。因此，大型负载可能会产生异常的运行性能，例如同步地进行负载投下/降落，或者频繁且同步地进行浇铸和降落，因此，可能会威胁配电网的安全性和稳定运行。首先，我们分析了工业可控负载，民用可控负载以及配电网络攻击的得失所面临的安全威胁。考虑到网络攻击的因素，我们提出了主动分配网络（ADN）中的控制模型和网络攻击模型。和，根据控制的“打开”和“关闭”模式，定义了目标遭受的三种攻击。然后，可控负载被恶意控制为研究对象，并选择了合适的场景。对可控负载的恶意控制对配电网络的供电可靠性和电能质量的影响进行了仿真和分析，并提供了不同类型攻击的风险后果。
