A New DC Charging Station to Control Power Flows on Low Voltage Grids

Dario De Santis

Abstract: With the development of power electronics and storage systems, the electric vehicles market has grown. So, for this reason low voltage electric grids are experiencing growth in the number of charging stations. There are several power levels to charge an electric vehicle with DC or AC voltage. This paper proposes a double three-phase power supply solution for DC charging stations to charge the vehicle battery and to control active and reactive power flows between two electric feeders using a low voltage UPFC.
