摘要
智能电网中由于各种智能设备与互联网连接,使其容易受到网络攻击的威胁。以智能电表、智能微电网和智能逆变器为例,对相应的安全风险和管控措施进行了研究分析。智能电表可能受到拒绝服务攻击和恶意软件攻击,威胁电量传输和数据隐私;智能微电网可能受到虚假数据注入攻击和分布式拒绝服务攻击,显著影响其功率和电压稳定性;智能逆变器可能受到欺骗攻击和勒索软件攻击,危害其正常使用功能。为了解决这些风险,提出了采用异常检测、二进制数据可视化、差分隐私技术、UIO观测器、KL散度、身份验证系统以及区块链技术等策略,这些措施可检测网络攻击、识别恶意软件、保护数据隐私、确保授权访问,增强了智能电网的安全性。
Due to the connection between various smart devices and the Internet the smart grid is vulnerable to cyber attacks.This article takes,smart meters smart microgrids,and smart inverters as examples to study and analyze the corresponding safety risks and control measures.Smart meters may be vulnerable to denial of service(DoS)attacks and malicious software attacks threatening power transmission and data privacy Smart microgrids may be vulnerable to false data injection attacks and distributed denial of service attacks significantly affecting their power and voltage stability Intelligent inverters may be vulnerable to deception attacks and ransomware attacks endangering their normal usage function.To address these risks,strategies such as anomaly detection binary data visualization differential privacy technology,UIO observer KL divergence identity verification system,and blockchain technology have been proposed.These measures can detect network attacks identify malicious software protect data privacy ensure authorized access and enhance the security of the smart grid.
