Different Fuzzy Control Configurations Tuned by the Bees Algorithm for LFC of Two-Area Power System

This study develops and implements a design of the Fuzzy Proportional Integral Derivative with filtered derivative mode (Fuzzy PIDF) for Load Frequency Control (LFC) two-area interconnected power system. To attain optimal values proposed structure’s parameters which guarantee best possible performance, Bees Algorithm (BA) other optimisation tools are used to accomplish this task. A Step Perturbation (SLP) 0.2 pu is applied in area one examine dynamic performance system controller employed as LFC The supremacy PIDF proven by comparing results those previous studies same As designed required provide reliable further extended propose three different fuzzy control configurations that offer higher reliability, namely Cascade PI − PD, plus (PI + PD), optimized BA dual-area Moreover, an extensive examination robustness these structures towards parametric uncertainties investigated system, considering thirteen cases, carried out. simulation indicate contribution tuned alleviating overshoot, undershoot, settling time frequency both areas tie-line oscillations. Based on obtained results, it revealed lowest drop −0.0414 Hz, achieved BA. It also divulged techniques, was evidenced their good transient response, considerable capability disturbance rejection, insensitivity uncertainty controlled
