AGC of an interconnected multi-area hydrothermal system using a neuro-fuzzy controller

This paper deals with automatic generation control of an multi-area hydro-thermal system. The performances of some commonly used classical controllers are examined and dynamic performances are compared to obtain the best. A three input neuro-fuzzy controller is proposed for the first time in the system. Investigations reveal that the three input neuro-fuzzy controller provides better performance than two inputs Controller. The performance of the three input neuro-fuzzy controller has been compared with that of the best commonly used classical controller, which reveals that the neuro-fuzzy controller is better. The robustness of the three input neuro-fuzzy controller has been tested for different loading. Comparison of the dynamic responses of neuro-fuzzy controller and the best classical controller at different loading conditions also reveal the superiority of the proposed neuro-fuzzy controller.
