Grey Wolf Optimization based 2DOF-PID Controller for Load Frequency Control

This work introduces a novel Grey Wolf Optimization (GWO) tuned two-degree-of-freedom proportional-integral-derivative (2DOF-PID) controller for load frequency control (LFC). LFC involves a set of control mechanisms that adjust the output of power generation units in response to changes in load and generation. Several modern techniques are applied to implement a stabilizing controller. An analysis of the dynamic performance of LFC using optimization method and the LFC problem in a power system with two power generating units has been established. In order to suppress oscillation, a 2DOF-PID control method is proposed in this study. The best controller parameters are found by applying recently developed algorithms. The controller performances are analysed by using the MATLAB/SIMULINK tool.
