Electric vehicle (EV) charging stations on the smart grid are needed to promote electric car adoption and sustainable transportation. The key issues are the lack of continuous monitoring and incident response, difficulty linking smart grid systems with EV charging stations, and security gaps that may not address particular vulnerabilities. Modern security measures are needed to protect the grid from those attacks, which may cause significant disruptions. Machine Learning Empowered Anomaly Detection with Grid Sentinel Framework (AD-GS) is proposed to safeguard electric car charging stations against intrusions. This technology can also detect and respond to suspicious movements dynamically using powerful machine learning algorithms (long short-term memory (LSTM), random forest, and autoencoder models), ensuring safety. The testing findings reveal that the systems are automatically updated to neutralize threats quickly, utilizing dynamic methods to minimize downtime. This method increases smart grid safety and can be applied beyond electric car charging stations. The AD-GS architecture is tested in simulations and shown to be resilient against extraordinary attacks, with no impact on charging station performance. The simulation showed that AD-GS could reduce downtime by implementing quick threat mitigation, improve smart grid response time efficiency by 98.4%, and detect abnormalities with 96.8% accuracy. This framework protects user and operation data 99.2% of the time. Extended AD-GS can monitor more than 500 stations and safeguard distribution networks, substations, and electric car charging stations.
智能电网上的电动汽车(EV)充电站对于促进电动汽车的普及和可持续交通至关重要。关键问题在于缺乏持续监控和事件响应能力、难以将智能电网系统与电动汽车充电站连接以及安全漏洞可能无法解决特定的脆弱性。需要现代安全措施来保护电网免受这些可能造成重大破坏的攻击。提出了基于电网哨兵框架(AD-GS)的机器学习赋能异常检测技术,以保障电动汽车充电站免受入侵。该技术还可以使用强大的机器学习算法(长短期记忆(LSTM)、随机森林和自动编码器模型)动态检测并响应可疑活动,确保安全。测试结果表明,系统会自动更新以迅速消除威胁,利用动态方法将停机时间降至最低。这种方法提高了智能电网的安全性,并且可应用于电动汽车充电站之外的领域。AD-GS架构在模拟中进行了测试,结果表明它能够抵御异常攻击,且对充电站性能没有影响。模拟显示,AD-GS通过实施快速威胁缓解措施可以减少停机时间,将智能电网响应时间效率提高98.4%,并以96.8%的准确率检测异常情况。该框架在99.2%的时间内保护用户和运营数据。扩展后的AD-GS可以监控500多个站点,并保障配电网、变电站和电动汽车充电站的安全。
