Application of high voltage gain DC-DC converter in photovoltaic system with energy storage

In this paper, the new structure of non-isolated boost dc-dc converter is considered as achieving maximum power transferring to load from a photovoltaic (PV) power network. To achieving maximum power point (MPPT) of operating mode, the Perturb-and-Observe (P&O) is applied after modeling of other part of this power network such as battery, bidirectional dc-dc converter and proposing new control scheme. To verify the proposed control scheme, performance of new structure of non-isolated boost dc-dc converter and power network, the simulation results of MATLAB/Simulink is used.
