In this article fractional order PID (FOPID) controller is optimally designed using Ant Lion Optimizer (ALO) and implemented to study load frequency control (LFC) issue in a two area thermal power system. Study of the transient analysis begins with realization of the two area thermal system from previously published articles based on conventional PI controllers. Then effort is made to improve the performance of the system employing ALO tuned conventional PID and FOPID controllers. Step load change of 1% in area1 of the power system is considered for transient analysis and integral time absolute error (ITAE) is selected as objective function in optimally designing PID and FOPID controllers. It is found that ALO tuned FOPID controlled AGC system performs better as compared to ALO tuned PID, hBFOA-PS, BFOA and GA based PI controller. Robustness analysis of the proposed ALO designed FOPID controller reveals that there is no need to retune the optimized controller parameters in case of system uncertainties and random load variation.
