Description
Summary:This paper proposes a new AC/DC power supply system with DGs using the parallel processing method. The purpose of this system is to supply the power without connecting to the utility gird. The DGs consist of photovoltaic (PV) and wind generators (WG), and the main energy source of this system is the DGs and the UPS battery. When the system does not get enough energy from the DGs, and the power supply of the battery runs out, this system connects to the utility grid and begins to charge the battery and supply to the load. In this study, we focused on the AC power supply and DC power supply from DGs. Then, the converter of DGs uses two kinds of DC/DC type and DC/AC type. Also, the load uses two kinds of DC load and AC load. The proposed the power system has been operated with the actual loads of 20 kW in the campus of the Aichi Institute of Technology.
