This article analyses the contribution of Fuzzy logic controller in a two source two area hydro thermal system aimed at load frequency control of the system. The proposed two area two source hydro thermal system is observed for different system parameter change to realize the dynamic behavior of frequency along with the interchanged power through tie line. To begin with, hydro and thermal power plants in a single control area for a step load variation is reviewed and the results for PI along with fuzzy logic controller are compared. Additionally a two source two area system is considered and the frequency and tie line power deviation with fuzzy logic controller is matched with results of PI controller. To witness the superiority of fuzzy logic controller, the connected generating system is run for different system parameter change. Simulation outcomes revealed that the recommended fuzzy logic controller put in enhanced output response when compared with conventional PI controller. The offsets found with the conventional controller can be estimably fell off with the suggested fuzzy logic controller.
