Abstract:

The smart transformer based on solid state transformer technology provides dc connectivity and power flow controllability increasing the hosting capacity of renewables and electric vehicle charging stations, and consequently reducing the need for updating the grid assets. In this context, this tutorial introduces the recent advancements in the field of smart transformer in terms of power semiconductor technology (e.g. 10 kV SiC), magnetic components (medium voltage, medium frequency and multi-winding), power converter topologies and architectures, connecting them to the services in power system when operating in radial, meshed and hybrid grids, with examples from pilot projects.
