Abstract In this paper, a false data injection attack scheme is developed for power systems in the framework of descriptor system. On account of generators dynamics and static power flows, a descriptor system model for power systems is firstly established. Then, a necessary and sufficient condition for perfect attack is given in terms of unstable eigenvector by the eigen-decomposition of system matrices. Based on this, a false data injection attack scheme, which can pass not only the observer detection but also the measurement limit detection, is presented to destabilize the power systems. The proposed scheme has the advantages of concealment and implementation simplicity when compared to the existing static attack counterpart. Additionally, the obtained results can help to understand the weakness of power systems and establish some more secure protective measures. Simulations on the IEEE 9 - bus and 14 - bus power systems demonstrate the superiority and effectiveness of the proposed method.

针对电力系统虚假数据注入攻击的描述符系统设计框架

摘要 本文在描述符系统的框架内，针对电力系统开发了一种虚假数据注入攻击方案。考虑到发电机动态和静态潮流，首先建立了电力系统的描述系统模型。然后，通过系统矩阵的特征分解，从不稳定特征向量的角度给出了完美攻击的充要条件。在此基础上，提出了一种不仅可以通过观察者检测而且可以通过测量极限检测的虚假数据注入攻击方案，以破坏电力系统的稳定性。与现有的静态攻击方案相比，所提出的方案具有隐蔽性和实现简单的优点。此外，获得的结果有助于了解电力系统的弱点，并建立一些更安全的保护措施。在 IEEE 9 总线和 14 总线电源系统上的仿真证明了所提出方法的优越性和有效性。
