Indian journal of pure & applied physics (IJPAP)Summary: This paper proposes a distributed generation system based on fuel cells and batteries. The primary energy source for thedistributed generation system is a proton exchange membrane fuel cell, with a lead-acid battery serving as the energystorage medium. A boost converter regulates the output power of a fuel cell to guarantee smooth operation. The battery isconnected with the fuel cell to meet the power demand of the distributed generation system. A buck-boost bidirectionalconverter is employed as an interface between the battery and the DC link capacitor. The bidirectional converter operates onthe slope compensated current control approach. Two 5-level cascaded H-bridge inverters have been installed to improve thepower quality of distributed generation systems. The power flow between the source, grid, and nonlinear load is controlledusing a sinusoidal pulse width modulation approach. Nonlinear current compensation and capacitor voltage balancing aretwo features that improve power quality.
