Developing power grids that are resilient under disruptive events is one of the main objectives of electric utilities. A light-weight mobile power substation connecting two distribution feeders having different voltage levels would be a useful piece equipment to be deployed under emergency conditions. To this end, the main goal of this project is to evaluate potential designs for a mobile power substation characterized by its light weight so it can be transported in a single truck to interface two medium-voltage distribution systems operating under emergency conditions. The research team would evaluate arrangements providing electric isolation or not. Electric isolation will be implemented through the use of a medium-frequency transformer. Initial research will be centered on the modular multilevel converter (MMC) used in HVdc terminals since it may lead to a design with the highest power density.
