SiC Power Converters-based Grid Infrastructure: Technologies, Challenges, and Grid Applications
Organizer: Akanksha Singh, National Renewable Energy Laboratory, Golden, CO, USA
Abstract:
The adoption of medium voltage (MV) SiC-based power electronics in the electric power grid would provide an important tool for ongoing efforts in grid modernization. The potential range of directly-connected MV power electronic converters for the future power grid infrastructure includes but is not limited to: MV to low-voltage conversion; AC to DC conversion to easily integrate inherently DC systems such as photovoltaics, battery systems, etc.; and MV to MV back-to-back converters which allow full asynchronous power flow control between intertied distribution systems. With the increasing commercial availability of high-quality and reliable SiC devices that can operate at voltages relevant to MV distribution utility applications, it is critical to develop a technical pathway for such applications to ensure the successful, widespread use of high-voltage SiC devices (3.3kV, 6.5kV, 10kV devices) and modules. This special session will focus on – a) capabilities and challenges enabled by the high-voltage SiC devices, b) the latest research progress and industry practice on design, development, and validation of high-voltage SiC devices, power modules, and power converters, and c) additional grid services and applications that can be realized using such power electronic converters, in advancing the power grid infrastructure.
