Abstract: (556 Views) |
This paper proposes a new load frequency control (LFC) method for multi-area power systems using the backstepping algorithm and fuzzy control based on decentralized control strategy. At first, a backstepping controller is designed for the single-area system, and the stability of the method is proved by the Lyapunov method. In addition to, in order to rejects large disturbances and making the system more robust against parameters variations an optimal supplementary fuzzy controller is used for decentralized LFC. For optimal performance of the two controllers, the particle swarm optimization algorithm is used to obtain the control parameters of the two controllers. Coordination and switching between the two controllers is done by a supervisory control strategy. Finally, sseveral simulations are performed on one area system, three area system and four area system. The merits of the proposed scheme include faster response speed, stronger robustness against disturbances and system parameter variations over the state-of the-arts.
