Abstract :
This paper presents the modeling and simulation of a fuel cell generation unit for off-grid and on-grid operation and configuration. A fuel cell unit consists of a fuel cell array, DC/DC converter and DC/AC inverter. The dynamic model for fuel cell array and its power electronic interfacing are presented; also a multi-input DC/DC converter and its control scheme is proposed and analyzed. This DC/DC converter is capable of interfacing fuel cell arrays to the DC/AC inverter. The suitable control strategy of DC/AC inverter for different operating conditions is demonstrated. The simulation results based on PSCAD/EMTDC software show the capability of fuel cell generation system for dynamic studying in the various operations.
