Cyber attacks are emerging threats in the Internet of Things applications, and power systems are typical cyber attack targets. As one of the most essential operation functions, frequency control is threatened by cyber intrusions, and the existing centralized control mode cannot effectively address cyber risks. In this study, a new distributed cyber-attack-tolerant frequency control scheme is designed. The distributed control mode also serves as a convenient tool for attack identification. The designed cyber-attack-tolerant frequency controller adopts the idea of passive fault attenuation, thus simplifying the design procedure. With the aid of graph theory and consensus techniques., distributed integral based and model predictive control (MPC) based controllers are designed. Compared with the integral type, the MPC-based controller can simultaneously improve the dynamic responses and the tolerance ability under attack. The proposed controller is validated via an IEEE benchmark system, and the effectiveness of its application in actual power systems is verified.

电力系统容忍网络攻击的频率控制

网络攻击是物联网应用程序中新兴的威胁，而电源系统是典型的网络攻击目标。作为最重要的操作功能之一，频率控制受到网络入侵的威胁，而现有的集中控制模式无法有效解决网络风险。在这项研究中，设计了一种新的分布式耐网络攻击的频率控制方案。分布式控制模式还可以用作方便的攻击识别工具。设计的耐网络攻击的频率控制器采用无源故障衰减的思想，从而简化了设计过程。借助图论和共识技术，设计了基于分布式积分和基于模型预测控制（MPC）的控制器。与整数类型相比，基于MPC的控制器可以同时提高动态响应和抵抗攻击的能力。所提出的控制器已通过IEEE基准系统进行了验证，并验证了其在实际电力系统中的有效性。
