1 FREEDM System: Changing The Paradigm for Innovation Dr. Alex Huang Progress Energy Distinguished Professor of Electrical and Computer Engineering Director, NSF FREEDM Systems Center NC State University 1

2 Innovation: What can it do in one hundred years! after Moravec

3 Innovation in Electric Distribution 1930s to 2009 We need a major paradigm shift in the industry 3

4 A Paradigm Shift like the Internet Pre-1980s Paradigm Shift Centralized Mainframes Internet Innovation & Industry Transformation Distributed Computing Shipping 250M pcs/yr. Ubiquitous ownership Ubiquitous use Ubiquitous sharing

5 Paradigm Shift for the Power Industry Today Paradigm Shift FREEDM System Centralized Generation New technologies for distributed renewable energy New energy companies based on IT and power electronics technologies Innovation & Industry Transformation Distributed Renewable Energy Resources (DRER) Ubiquitous sales Ubiquitous ownership Ubiquitous use Ubiquitous sharing

6 A Comparison Internet/Computer 1) Plug-and-Play Interface (RJ45, USB) Power Grid 1)? 2) Router 2)? A New Grid Like an Energy Internet 3)Open Standard Protocol and Operation System (TCP/IP, HTML) 3)?

10 Project Y1.E.C5 Prof. Raja Ayyanar (ASU) Simulated SST Capabilities A SST model is developed and used by center teams Unity power factor or arbitrary VAR support Voltage regulation (120V And 400VDC) Voltage Sag Rid Through Short circuit current limiting

11 Comparison With Existing Systems FREEDM System Plug-play interface Energy Router Distributed Operation Sys. High DER/DESD penetration Two-way power flow Demand side management Fault current limited Unit power factor Self-healing ability Improved reliability Enabling energy market. Existing System Non plug-play connection No energy router or gateway No info or manual operation Low DER/DESD penetration One-way power flow No direct demand side management High fault current Non unity power factor Manual restoration lower reliability No energy market 12
