Electricity theft poses significant challenges to utility companies worldwide, resulting in substantial financial losses. This study addresses the problem by leveraging machine learning algorithms to detect energy theft in smart grids. The insufficiency of data on theft conditions and the imbalance of datasets have always hindered the precise identification of fraudulent activity. To mitigate these challenges, we curated a dataset from the Open Energy Data Initiative, which encompasses sixteen consumer categories and six theft conditions. Our approach focuses on using the Synthetic Minority Oversampling Technique (SMOTE) to address class imbalance by generating synthetic samples for minority classes. We conducted a comparative analysis of various machine learning based classification algorithms, including K-Nearest Neighbors (KNN), Decision Tree, Random Forest (RF), Bagging with RF, and Ensemble Learning, and observed the results before and after the implementation of SMOTE on the dataset. We find that SMOTE demonstrates its most significant impact on classifying the most challenging classes within the dataset. In particular, it shows improvements of 57.00%, 37.88%, and 36.88,% for Class 6, Class 1, and Class 3, respectively, with the KNN algorithm. Other algorithms also indicate significant increments in terms of accuracy, kappa, F1-score, and AUC metrics in detecting fraudulent activity. Overall, this research contributes to advancing energy security by highlighting the importance of robust theft detection frameworks for safeguarding energy distribution systems.

Industry 4.0, also known as the Fourth Industrial Revolution, is characterized by the incorporation of advanced manufacturing technologies such as the Internet of Things (IoT), Artificial Intelligence (AI), and automation. With the increasing adoption of Industry 4.0 technologies, it becomes crucial to implement effective security measures to safeguard these systems from cyber attacks. The development of intrusion detection systems (IDS) that can detect and respond to cyber threats in real-time is crucial for securing Industry 4.0 systems. This research topic seeks to investigate the various techniques and methodologies employed in developing IDS for Industry 4.0 systems, with a particular concentration on identifying the most effective solutions for protecting these systems from cyber attacks. In this study, we compared supervised and unsupervised intrusion detection algorithms. We utilized data collected from heterogeneous sources, including Telemetry datasets of IoT and The industrial Internet of things (IIoT) sensors, Operating systems (OS) datasets of Windows 7 and 10, as well as Ubuntu 14 and 18 TLS and Network traffic datasets simulated by the School of Engineering and Information Technology (SEIT), UNSW Canberra @ the Australian Defence Force Academy (ADFA). The preliminary results of IDS accuracy are extremely encouraging on the selected data for this study (Windows OS and Ubuntu OS), which motivates the continuance of this line of inquiry using a variety of other data sources to formulate a general recommendation of IDS for Industry 4.0.
