Novel controller scheme for grid connected fuel cell

The operation of the distributed generation system with Fuel Cell (FC) is analyzed in this paper. FC is incorporated to distribution system with inverter and inverter controller is proposed to supply the real power to distribution system as well as to work as DSTATCOM. Highlights the benefits of using DSTATCOM are presented in this paper. The purpose of DSTATCOM is to mitigate the voltage sag and to make proper power flow control in the system. Then hybrid controller is proposed for inverter in this paper, so this controller mitigates sag, compensate reactive power and improve voltage stability. Hence, the system maintains good power quality at load. Based on extensive simulation results using MATLAB/Simulink it has been established that the performance of the controllers is quite satisfactory under both in transient as well as in steady state condition.
