A digital testbed for FREEDM system development

In this paper, a notional Future Renewable Electric Energy Delivery and Management (FREEDM) system has been developed based on a real distribution feeder. The goal is to develop a digital testbed which can be used to show capabilities of this system, and to help the development of especially the new system components and the control schemes for this system. Two digital testbeds have been developed, one to represent the small scale green hub that will be realized in the center´s test facilities at North Carolina State University and the other is a more detailed notional system that can be used for large scale system level analysis and design.
