摘要：In near future, fuel cell (FC) based power generation system will witness higher scalability due to merits like reliability, portability and negligible environmental impact. This paper presents grid integrated fuel cell generator as micro grid and interacts with modeling and simulation of control architecture (voltage, active and reactive power) along with vital design aspect of interface filter. The fuel cell system output is connected to current controlled voltage source converter (VSC) which controls active and reactive power. Power balance control theory (PBCT) is used to generate gate pulses for VSC. Hybrid fuzzy PI controller is used to attain constant DC link voltage. Simulation of entire system based on fuel cells is undertaken through MATLAB/Simulink software. PBCT and synchronous reference frame theory (SRFT) control strategies are also compared for grid connected FC system.
