Abstract

This paper studies the voltage restoration problem of the DC Microgrid (MG) cluster with a two-layer communication structure under Denial-of-Service (DoS) attacks. Based on the open multiagent framework, an asynchronous switching strategy is designed to suppress the impact of DoS attacks on the entire MG cluster’s voltage restoration. Meanwhile, we derived the relationship between attack model parameters and communication link switching mode selection through the general model of DoS attacks and asynchronous switching methods based on average dwell time. Moreover, the designed distributed control protocol is scale-free; that is, it does not rely on any information from the two-layer communication structure and the number of distributed generations (DGs), which makes it universal. Through rigorous theoretical proof, it has been proven that in the DC MG cluster with two-layer communication structures, voltage restoration can be achieved regardless of the number and structure of DGs being attacked. Finally, two simulation examples on the MATLAB/SimPowerSystem, including a DC MG cluster consisting of 8 DGs and an IEEE 33-node system are used to investigate the scalability and flexibility of the proposed distributed control algorithm.

DoS攻击下数据中心MG集群的无标度分布式控制：异步切换策略

研究了具有两层通信结构的直流微电网集群在DoS攻击下的电压恢复问题。基于开放多代理框架，设计了一种异步切换策略，抑制DoS攻击对整个MG集群电压恢复的影响。同时，通过DoS攻击的一般模型和基于平均停留时间的异步切换方法，推导出攻击模型参数与通信链路切换方式选择之间的关系。此外，所设计的分布式控制协议是无标度的；也就是说，它不依赖于任何来自两层通信结构和分布式代（dg）数量的信息，这使得它具有通用性。通过严格的理论证明，证明了在具有两层通信结构的直流MG集群中，无论被攻击dg的数量和结构如何，都可以实现电压恢复。最后，在MATLAB/SimPowerSystem上进行了8 dg组成的DC MG集群和IEEE 33节点系统的仿真，验证了分布式控制算法的可扩展性和灵活性。

期刊介绍： Automatica is a leading archival publication in the field of systems and control. The field encompasses today a broad set of areas and topics, and is thriving not only within itself but also in terms of its impact on other fields, such as communications, computers, biology, energy and economics. Since its inception in 1963, Automatica has kept abreast with the evolution of the field over the years, and has emerged as a leading publication driving the trends in the field. After being founded in 1963, Automatica became a journal of the International Federation of Automatic Control (IFAC) in 1969. It features a characteristic blend of theoretical and applied papers of archival, lasting value, reporting cutting edge research results by authors across the globe. It features articles in distinct categories, including regular, brief and survey papers, technical communiqués, correspondence items, as well as reviews on published books of interest to the readership. It occasionally publishes special issues on emerging new topics or established mature topics of interest to a broad audience. Automatica solicits original high-quality contributions in all the categories listed above, and in all areas of systems and control interpreted in a broad sense and evolving constantly. They may be submitted directly to a subject editor or to the Editor-in-Chief if not sure about the subject area. Editorial procedures in place assure careful, fair, and prompt handling of all submitted articles. Accepted papers appear in the journal in the shortest time feasible given production time constraints.
