A review of artificial intelligence techniques for anomaly detection in smart grid
This comprehensive review highlights the critical role of Machine Learning (ML) and Artificial Intelligence (AI) in enhancing the security, reliability, and efficiency of Smart Grids (SGs). With the increasing integration of diverse and renewable energy sources, SGs face complex challenges, including electricity theft, cyber-attacks, power system disturbances, and abnormal consumption patterns. Our study systematically classifies these anomalies and evaluates various ML models (supervised, unsupervised, semi-supervised, and reinforcement learning) based on their ability to detect and mitigate these threats. We discuss their nuanced capabilities, limitations, and practical applications, providing a clear understanding of how they contribute to SG resilience.
