2 Overview History of work in USAFA/DFEC Current State of Lab SCADA Network Future of Energy Research at USAFA

3 Energy Lab History Capstone Projects 2013/14 SCADA Network System 2012/13 Autonomous Electric Vehicle 2011/12 Solar Electric Vehicle 2010/11 Energy Lab Establishment (RT-19) 2009/10 Wind Generation System 2008/09 Solar Powered Sound System 2010/11 Visiting Professor (Dr. Hess, U of Idaho) Renewable Energy Experience Consulted for Energy Lab Development Work with outside agencies NREL Colorado School of Mines Sully Research Colorado Springs Utilities 10 th Air Base 1 April

4 Current Capabilities Two Solar Arrays about 3.5kW each Reconfigurable Very Visible Energy Data Collection Inverter and Battery System Web Page development in progress Renewable Energy Awareness Kiosk station developed 12kW-h electric dune buggy with 18kW-h base station Trailer and vehicle make up the autonomous electric vehicle for forward deployed operations without fuel support chain. SCADA network in construction

5 Characteristics of Future Deployed Grid Premise: To reduce long term costs future deployed grids will contain a mix of traditional diesel generators, renewable generation, power storage, and automated control Diesel generators will supply dispatchable energy Solar, wind or other renewable to provide large percentage of base load Storage system required to compensate for unreliability of renewable sources Control network to real time manage 1 April

6 Proposed System

7 Proposed System Primary Control Node

8 Proposed System Primary Control Node Power Generation & Storage

9 Proposed System Primary Control Node Power Generation & Storage Controllable Load

10 Proposed System Primary Control Node Power Generation & Storage Network Possibly Wireless Controllable Load

11 Proposed System Primary Control Node Power Generation & Storage Network Possibly Wireless Controllable Load Secondary Control Node

12 Proposed System Primary Control Node Power Generation & Storage Network Possibly Wireless Controllable Load Secondary Control Node Remote System or Subsystem

13 Proposed System Primary Control Node Power Generation & Storage Must Protect Network Possibly Wireless Controllable Load Secondary Control Node Remote System or Subsystem

14 SCADA Network Model

15 Control Use Standard SCADA Programmable Logic Controllers From Siemens Plug and play with Siemens controllers and ADCs Scalable network with multiple controllers Touch screen Simple programing Vulnerabilities are known

16 Power 1 April 2014 Solar generation and battery storage 7kW generation capacity 14KW-h storage Not sufficient to survive the night 16

17 Load Programmable load bank 1500W capacity selectable in 100W increments Standard Siemens interface 1 April

18 Bringing it all Together 18

19 Bringing it all Together Network 19

20 Bringing it all Together Network Networked components Connects various system Provides potential for control Opens potential vulnerabilities Network security is an issue Likely not a significant external threat due to closed nature of the system Internal threats always a problem 20

21 Next Year Deployed operations bare base mock up Possible location in existing cadet training area 10s of KW load Multiple sources Micro-grid island with control Use Boeing funding. 1 April
