Abstract: In this paper, a new tilt integral derivative (TID) controller is implemented for a multi-area multi-source power system. The parameters of the TID controller are optimised using a firefly algorithm (FA) and it is employed with integral time multiplied absolute error (ITAE) as an objective function. Initially, three-area nine-unit power system is designed in MATLAB/Simulink environment. The superiority of the proposed controller is established by comparing simulation results Ziegler-Nichols (ZN)-based PID and FA-based PID controllers for the same designed model. The simulation results reveal that frequency responses and tie-line power deviations are enhanced with FA-based TID when compared to ZN and FA-based PID controller. Finally, the effectiveness of the proposed controller is examined by doing robust analysis under varied system parameters.
