Abstract

The performance and environmental benefits of fuel cells make them a popular choice for distributed generation systems (DGs). Fuel cells are connected to the network using power electronic converters. Power inverters have high frequency harmonics due to PWM switching and its control delays. LCL filters are used to eliminate these harmonics. Network impedance changes affect the resonant frequency of LCL filters and may cause system instability. Active damping methods are used to weaken the resonance of LCL filters. In this paper, a fuel cell system is used to inject power into the grid through a power inverter and LCL filter. Integral-proportional capacitor current feedback is used for LCL filter resonance damping. MATLAB/Simulink simulation results are presented to verify the validity of the proposed method. Integral-proportional capacitor current feedback is used for LCL filter resonance damping. MATLAB/Simulink simulation results are presented to verify the validity of the proposed method.The simulation results show that the proposed method is stable against changes in network impedance and fuel cell parameters, and provides a good performance. The simulation results show that the proposed method is stable against changes in network impedance and fuel cell parameters, and provides a good performance.
