Abstract
The world’s growing economy and demographic advancement are driving an increase in global energy demand. As worries about carbon emissions grow and the demand for electrical energy production continues to rise, it is necessary to develop new methods of electricity production. Fuel cell energy system is one of the promising factors for addressing this problem due to its low emissions, easy accessibility, and fuel flexibility. In this paper, a mathematical model of Solid Oxide Fuel Cell (SOFC) is designed and used as an input for the KY converter. As the output voltage of the fuel cell is low, a KY Converter is desired to raise the output voltage for required applications. To regulate the electrical output voltage of the KY Converter, PID, Fuzzy Logic Controller (FLC), hybrid fuzzy PID, and an ANFIS feedback control mechanism have been simulated and investigated. The function of a fuel cell with a KY Converter, as well as state-space modelling, is developed. The Ziegler-Nichols technique is used to determine the gain parameters of a PID controller, which are Kp, Ki, and Kd. The fuel cell with a Closed-loop system of KY converter is developed using MATLAB/Simulink software. Thus, the fuel cell power system can be used for a variety of applications, including rural and military.
