| Distributed generation (DG) using a parallel battery pack with photovoltaic (PV) system has been presented in this paper. For this aim, first modeling of a photovoltaic package has been illustrated. Then, a DC/DC converter has been considered as the PV power controller and a battery pack has been connected to its output. Considering a two level inverter and a three phase’s transformer, a local load will supplied by the DG and connected power grid. The DG has been connected to the high voltage network via a filter and a distribution power station. Since the power capacity of PV system is depended to both temperature and irradiance, a Nero-Fuzzy network has been designed for estimation of maximum power ability of PV. To producing of obtained power by the PV system, the connected DC/DC converter has been controlled relatively. So, the power management between the PV system and the battery pack can be confirmed. In the other hand, another controller has been design for control of transferred power between the power network and DG system that can control the battery pack power indirectly. Finally, a series of simulation results shows the effectiveness of proposed method for some various conditions such as different temperature, difference irradiations and also various state of charge of battery pack. |
