Comparative study of power sharing algorithm for fuel cell and photovoltaic hybrid generation system

In this paper, according to power sharing algorithm and types (2 Con & 2 Inv, 2 Con & 1 Inv, 1 Con & 1 Inv) of photovoltaic (PV) and fuel cell (FC) hybrid generation system, control algorithms of converter and inverter are presented. Almost algorithms of PV and FC hybrid generation system are performed and verified to use by technology for commercialization. Moreover, a comparative study are performed with respect to the efficiency, dc-link voltage variation, MPPT, output current, scalability and system size and cost. Base on these studies, selection guide line of PV-FC hybrid generation system is presented. In order to verify these, informative simulation and experiment are carried out.
