Authors : Bahri Hamza . Harrag Abdelghani .

Abstract

This paper addresses the development of three-phase grid connected fuel cell energy system using Matlab/Simulink Stateflow environment. The proposed grid connected fuel energy system designed by considering a 5.5kW proton exchange membrane fuel cell connected to the grid via a double stage including a DC-DC boost converter and three phase inverter. The whole energy system has been implemented using Matlab/Simulink Stateflow environment where all the parameters and operating conditions have been considered. The proposed energy system has been tested and validated using Matlab/Simulink under different test scenario representing different operating conditions. Simulation obtained results prove the efficiency of the developed stateflow models to characterize and analyzing the PEM fuel cell power system as well as the connection to the grid. The developed models can be used as a platform to analyze the performance of the system in connected or unconnected cases.
