In this paper, signified a novel method to strategy of FOPID controller for LFC of a three area generating units. In this system, LFC of generating units of power plants has been used in frequency control due to having the better responses. The EHO and GCMBO are also considered using the parameters of FOPID controllers as a minimization of error in this optimization technique. The Integral Squared Error (ISE) is the objective function for optimum strategy of FOPID parameters of the EHO and GCMBO technique. Its gives the better dynamic response as compared the other FOPID controller parameters. The modal of generating units power plant with FOPID controller is simulated in MATLAB/SIMULINK platform. In this study, simulation explorations on a three-area LFC with different generating units. The effectiveness of the proposed methodology is better in terms of settling time, rise time, and peak time. The perturbation in load, change the system frequency which further increase the Undershoot of the system here, the undershoot of the system is decrease for EHO and GCMBO technique is used to tuned the parametric value of FOPID controller.
