Traditionally, protection systems relied on electromechanical and later digital relays based on deterministic principles such as overcurrent, distance, differential, and frequency protection. However, with the increasing complexity of modern power systems\u2014driven by deregulation, renewable energy integration, distributed generation, and smart grids\u2014conventional protection schemes have faced significant challenges.<\/p>\n<p data-start=\"827\" data-end=\"1258\">Artificial Intelligence (AI), encompassing techniques such as expert systems, neural networks, fuzzy logic, genetic algorithms, and more recently machine learning and deep learning, has emerged as a transformative approach to enhancing power system protection.
