Abstract
This article presents an equivalent dynamic model of a Solid Oxide Fuel Cell (SOFC) integrated with utility grid. The proposed dynamic model accounts for the electrochemical and thermodynamic characteristics of SOFC. Effects of temperature variations and fluid flow changes are incorporated in the model. Voltage drops inside a fuel cell are also modeled. This proposed model is further integrated with the utility grid with help of power conditioning unit (PCU). PCU consists of a DC-DC Boost converter and a 3-phase voltage source inverter. The output of 3-phase inverter is fed to the grid with the use of AC link integration. Complete model is formulated in MATLAB-SIMULINK environment. Simulation results clearly depict the behavior of SOFC and also show that SOFC is a potential source for distributed generation purpose. The proposed model formulated here would be helpful for the optimal prediction of characteristics and dynamic operation of SOFC based power plants.
