Abstract: Frequency regulation is a vital function for ensuring the stability and reliability of electrical grids. As the global energy mix evolves, characterized by a growing share of renewable energy sources and increasing electrification, maintaining grid frequency within the prescribed operating range has become more complex. Traditional power systems, which depend on synchronous generators, are increasingly supplemented by variable and decentralized generation resources, such as wind and solar power. These renewable sources are intermittent, creating challenges for frequency regulation mechanisms. This paper provides a comprehensive review of the mechanisms for frequency regulation in electrical grids, including primary, secondary, and tertiary control, and explores the role of ancillary services in maintaining grid stability. Additionally, emerging technologies such as energy storage systems, demand response programs, and the application of artificial intelligence and machine learning are discussed as potential solutions for addressing the challenges of modern frequency regulation. The future of frequency regulation is shaped by technological advancements that enhance flexibility, efficiency, and system resilience, ensuring the continued stability of grids in the face of an evolving energy landscape.
