This paper presents a variable structure-based approach to the load frequency control problem in electric power generation systems. The approach combines salient features of variable structure systems and fuzzy systems to achieve high performance and robustness. For this, fuzzy tuning is proposed to continuously adjust the controller parameters according to the area control error. Simulation results indicate that the control scheme is able to substantially enhance control performance in single-area as well as multi-area interconnected systems with non-reheat or reheat turbines. Furthermore, it is shown that responses of the system employing the proposed controllers are rather insensitive to parameter changes and speed governor deadband, with and without generation rate constraints. The control strategy requires low computational cost and is amenable for practical implementation.
