摘要:

随着信息技术的不断发展,智能电表被广泛部署在许多家庭中,方便电力公司更好地识别电力消费者的社会人口特征并提供多样化服务。然而,智能电网面临的威胁之一是能源盗窃,尤其是通过虚假数据注入攻击(FDIA)篡改电表数据实现的隐蔽性盗窃,成为影响电力系统安全和稳定运行的严重隐患。针对这一问题,提出了一种基于LightGBM的FDIA检测模型。选取正常用户的用电数据并对部分用户实施不同类型的FDIA,通过滑动窗口方法提取特征,利用LightGBM模型进行多分类检测。试验结果表明,该模型在检测精度和实时性方面表现优异,能够准确识别出不同类型的FDIA,且检测过程快速高效,满足实际应用的实时性要求,可为电力系统的安全运行提供保障。

Abstract:

With the continuous development of information technology, smart meters have been widely deployed in many households, allowing power companies to better identify the socio-demographic characteristics of power consumers and provide diversified services. However, one of the threats faced by smart grids is energy theft, particularly through False Data Injection Attacks (FDIA), which tamper with meter data for covert theft, posing a serious threat to the safe and stable operation of power systems. To address this issue, an FDIA detection model based on LightGBM was proposed. Normal user electricity consumption data was selected, and different types of FDIA were implemented on some users. Features were extracted using a sliding window method, and the LightGBM model was employed for multi-class detection. Experimental results showed that this model excelled in detection accuracy and real-time performance, accurately identifying different types of FDIA with quick and efficient detection, meeting the real-time requirements of practical applications. This model could help ensure the safe operation of power systems.
