In the distribution generation system the use of power electronics technology together with renewable energy sources plays an important role for satisfying the increasing demand of electric power all over the world. Among the various distribution generation technologies, fuel cell based distribution system appears to be a promising technology. In this paper, a Solid Oxide Fuel Cell for distribution generation application is introduced. The mathematical modeling of the fuel cell is studied and simulation study of the interfacing power electronics converters is done in this paper. The physical model of fuel cell stack and power conditioning units are described in this paper. The control design methodology for each component of the proposed system is also described. A MATLAB/Simulink simulation model is developed for the SOFC DG system by combining the individual component models and the controllers designed for the power conditioning units. Simulation results are given to show the overall system performance including the real and reactive power compensation capability of the distribution system.
