More Details
As power electronics systems on the grid are increasing due to integration of new distributed energy resources couple with the evolution of loads such as EV charging, smart homes, and server farms, there is increased pressure on the utilities to interface, control, coordinate and optimize these various systems. This work supports the GMLC 2019 project entitled “Multi-Port Modular Medium-Voltage (M3) Transactive Power Electronics Energy Hub.†The overall intent of this project is to design, develop, and demonstrate foundational technologies and capabilities for multiport power electronics energy hubs (a.k.a. HUB) that can serve as intelligent devices to coordinate and control several different sources and loads.
As part of this project, NCSU will support two primary aspects of the HUB hardware. The first is to duplicate a 50 kW isolated DC-DC converter based on the high frequency bi-directional isolated 2 port dc-dc power stage developed under “Combined PV and Battery Grid Integration Enabled Through High Frequency Magnetics: (SuNLaMP) GMLC (31004).†The second is the development and demonstration of a 3.3 kV H-bridge power stage to support the MV HUB concept. Both pieces of hardware will be delivered to ORNL for integration and testing into the larger M3PE HUB configuration.
