To standardize the active power flow in the interlinked power systems, the
controller must be crafted in such a way that it would improve the system's stability.
With this objective, the paper is dedicated to the hybrid flower pollination algorithm: a
metaheuristic optimization algorithm (hFPA) applicable to optimize the parameters of
the PI and PID structure-controller incorporated in the two-area power systems. The
projected algorithm is compared with the articles published where the PI and PID
controller structure parameters upgraded with hFPA are compared with the enhanced
strength Pareto differential evolution and grey wolf optimization algorithms to
demonstrate its robustness for a vast span of system parameters and varying load
situations. The superiority of the technique has been presented in respect of peak
undershoot, settling time, peak overshoot, tie-line power, frequency divergence, etc.
