Abstract: As the surrounding problems of the states and the requirement to meet out the increasing energy demand are increasing gradually generation of distributed nature system based various types of clean power systems are being erected increasingly to manage the load side energy requirements and reduce the environmental issues. Fuel cell is the latest technology that can use as DG system and solve the above mention issues. In this research work, a grid-connected dynamic state of solid oxide fuel cell (SOFC) system is represented. The fuel cell stack DC voltage needs to be converted and stepped-up to match the load side grid. So, a DC-AC voltage source converter is utilized to for interfacing the fuel cells with the load side grid, and the transformer is installed for increasing the potential level to match the voltage grid. Two types of control strategies are presented (PI and hysteresis current controller) to control and shape the inverter output voltage, hence provides decoupled real and reactive energy. The entire work is modeled in MATLAB/Simulink.
