DESIGN OF AUTOMATIC GENERATION CONTROL FOR THERMAL AND GAS POWER PLANTS USING FRACTIONAL ORDER PID CONTROLLER

Abstract

As the Electricity demand continuously rising daily, Automatic Generation Control (AGC) is imperative for enhancing the production of electricity generation. Whenever there is change in load in AGC is important in adjusting the power output of different generators in multiple power plants. Generally, most research focuses on either thermal or hydropower plants. But the combination of multiple generators is more realistic in nature for the study of Automatic Generation Control. Furthermore, current techniques for designing control gains in integral, proportional-integral (PI), and proportional-integral-differential (PID) controllers for AGC are frequently time-consuming and rely on the designer’s knowledge. To overcome the demerits, A fractional-order PID (FOPID) Controller is proposed to increase system stability and decrease the values of overshoot and settling time. The fractional-order (FO) controller is renowned for its extraordinary tolerance to uncertainty and high disturbances as well as its superior dynamic responsiveness. Both gaseous and Thermal power plants are considered in frequency regulation in this proposed control approach.
