A consensus-based distributed voltage control architecture of isolated DC microgrids (MGs) with deception attack awareness is investigated in this paper. Firstly, a fully distributed voltage control algorithm with only adjacent information sharing is proposed by expanding the consensus-based distributed algorithm in AC MGs. To further enhance the ability of deception attack detection in the associated cyber network, an analytical consistency-based anomaly detection mechanism is also developed by manipulating primal variables and dual variables associated with the proposed distributed voltage control algorithm. Strategies for detecting either individual or stealthy false-data injection attacks on both links and nodes of the associated communication network against the distributed consensus-based droop control of DC MGs are investigated. Numerical experiments of a DC MG on real-time simulators are performed to validate the efficacy of the proposed deception attack detection mechanism.

基于共识的分布式电压控制架构下隔离直流微电网的欺骗攻击检测

本文研究了一种具有欺骗攻击意识的基于共识的分布式直流微电网（MG）分布式电压控制架构。首先，通过在AC MG中扩展基于共识的分布式算法，提出了一种仅具有相邻信息共享的全分布式电压控制算法。为了进一步增强相关网络中欺骗攻击检测的能力，还通过操纵与所提出的分布式电压控制算法相关的原始变量和对偶变量，开发了一种基于分析一致性的异常检测机制。研究了针对DC MG的基于分布式共识的下降控制来检测相关通信网络的链路和节点上的单个或隐匿虚假数据注入攻击的策略。
