Abstract
The load frequency control (LFC) of a single-area thermal power system is provided in this study. An evolutionary method known as ant colony planning is used to enhance the features of the proportional-integralderivative (PID) controller, a typical industrial auxiliary controller (ACO). Three cost functions are looked at to raise controller gain values. This study takes into account three different stem configurations in addition to integral absolute error (IAE), integral temporal absolute error (ITAE), and integral square error (ISE) (non-reheat turbine, single-stage reheat turbine, and double-stage reheat turbine).The effectiveness of the suggested approach is further demonstrated by including non-linearity (Generation Rate Constraint, Governor Dead Band, and Boiler Dynamics) into the same power system and changing the value of Step Load Perturbation (SLP) in each of the three steam configurations. The operation of electricity systems under diverse conditions is investigated using time domain analysis.
