A State-of-the-Art Review on LFC Strategies in Conventional and Modern Power Systems

This review paper reflects a detailed and up to date review on Load Frequency Control (LFC) in traditional and modern power systems. A general overview of LFC is provided, followed by a discussion of different configurations of power systems and their features. Various control strategies concerning the LFC problem, such as centralized and decentralized are also highlighted. Finally, LFC techniques based on classical, optimal, adaptive, robust, and artificial intelligence-based on soft computing are identified.
