Automatic generation control of an interconnected hydro-thermal system using conventional integral and fuzzy logic controller

This paper deals with automatic generation control of interconnected hydrothermal system in the continuous-discrete mode using conventional integral and fuzzy logic controllers. Effects of variation of sampling time period on dynamic responses have been investigated, both with conventional integral controller and fuzzy logic controllers, considering small step perturbations. Effects of different number of triangular membership functions and inputs for fuzzy logic controller on dynamic response have been explored. Further, dynamic responses under small step perturbation have been compared, considering integral and fuzzy logic controllers.
