Distributed generation (DG) using a parallel battery pack with photovoltaic (PV) system has been presented in this brief. Considering a two level inverter and a three phase transformer, a local load will be supplied by the DG and connected to a power grid. The DG has been connected to the high voltage network via a filter and a distribution power station. A nero-fuzzy network has been designed for the estimation of maximum power ability of PV and the connected dc/dc converter has been controlled relatively. So, the power management between the PV system and the battery pack can be confirmed. On the other hand, another controller has been designed for control of transferred power between the power network and the DG system that can control the battery pack power indirectly. Finally, a series of simulation results show the effectiveness of proposed method for some various conditions.
