Abstract

The DC-Microgrids (DC-MGs) are increasingly prone to various cyber-attacks due to the advancement of intelligent controlling, monitoring, operation methods. A typical DC-MGs integrates components like batteries, super capacitors, electronic devices, Photovoltaic (PV) systems, and loads. Given these vulnerabilities, cyber-attack detection, and the security of data exchanged in smart DC-MGs, similar to Cyber-Physical Systems (CPS), have become critical areas to focus. This paper proposes a novel approach to detect false data injection attack (FDIAs) in DC-MGs using Wavelet transform and Support Vector Machines (SVMs) with Blockchain technology. The analysis shows that the output voltage dropped from 350 V to 300 V during the False Data Injection Attack (FDIA) at 0.4 s and returned to 350 V by 0.7 s. Significant oscillations observed between 0.4 and 0.7 s and detection model achieved 400 true negatives, 191 true positives, 10 false negatives, and no false positives, demonstrating high accuracy in identifying FDIA instances.

利用区块链技术和SVM技术增强智能直流微电网的网络安全与网络攻击检测

随着智能控制、监控、运行方式的不断发展，直流微电网越来越容易受到各种网络攻击。典型的dc - mg集成了电池、超级电容器、电子设备、光伏（PV）系统和负载等组件。鉴于这些漏洞，网络攻击检测和智能dc - mg中交换数据的安全性，类似于网络物理系统（CPS），已成为重点关注的关键领域。本文提出了一种基于区块链技术的支持向量机（svm）和小波变换的dc - mg伪数据注入攻击检测方法。分析表明，在虚假数据注入攻击（False Data Injection Attack， FDIA）过程中，输出电压在0.4 s从350 V下降到300 V，并在0.7 s后恢复到350 V。在0.4和0.7 s之间观察到显著的振荡，检测模型实现了400个真阴性，191个真阳性，10个假阴性，没有假阳性，表明识别FDIA实例的准确性很高。
