In this work, an analytical study of type-2 fuzzy fractional-order PD-PI (T2FFOPDPI) controller in a microgrid system (MGS) has been carried out for frequency regulation. The MGS contains a combination of renewable generations, different storage and electric vehicles. The controller parameters are optimised by enhanced Harris hawks optimisation (EHHO) technique. The efficiency of EHHO method is compared with HHO and other optimization techniques for the PID controller. The MGS analysis is executed under increased load, decreased renewable powers, unavailability of renewable sources, and reduction in system parameters. The performance of the suggested EHHO-based T2FFOPDPI method is examined by fuzzy PID (FPID), T2FPID and a recent approach. Finally, the competency of the suggested method is investigated through OPAL-RT real-time simulator.
