Smart transformer universal operation [PDF]

open access: yes2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018
The Smart Transformer (ST) has been proposed for increasing the hosting capacity of renewable energy sources in the power system with advanced control and communication capability. Its capability to connect-and disconnect itself from the main grid and to provide power from the Low Voltage (LV) grid to the Medium Voltage (MV) grid in the grid forming ...
