Maiden application of fuzzy logic based IDD controller for automatic generation control of multi-area hydrothermal system: A preliminary study

This paper dealts with automatic generation control of an unequal multi-area hydrothermal system. The performances of several classical controllers such as integral (I), Proportional Integral (PI), Proportional — Integral — Derivative (PID) and Integral — Double Derivative (IDD) are compared, and it is found that IDD controller gives better performance over the other controllers. This study also attempts a maiden application of a genetic algorithm optimized fuzzy logic based Integral-Double Derivative controller (FIDD). The comparison on dynamic performances of IDD and FIDD controllers reveals that the FIDD controller is better. The robustness of the FIDD controller is also evaluated for different loading conditions.
