6. Mission Purpose of Existence

7. Mission Statement The mission of SimBoulder is to demonstrate the effective integration of renewable energy power sources

8. Baseline Objectives  Model City Power Infrastructure -residential, industrial, commercial and transportation -varying load characteristics -varying power usage based on time of day  Integrate renewable and traditional power sources -sense and control percentage of power taken from each source -integration of renewable and traditional sources -storage of renewable and grid power

9. Baseline Objectives  Measurement and Display -traditional vs. renewable energy sources -real-time power consumption -Cost & Environmental foot print comparisons  Energy Management Demo -incandescent vs. fluorescent -insulation -conservation

10. Function Specifications Boulder  Pop. = 90,000  Power consumption = 200 MW  Size = 30 square miles  Time = 24 hrs SimBoulder Population = 0 Power consumption = 2 W Size = 8 square feet Time = 2.4 min Ratio Power consumption & Area = 100,000,000:1 Time = 600 : 1

11. Functional Specifications Division of Energy Residential – 22% Industrial – 32% Transportation – 28% Commercial – 18%

12. Functional Specifications

13. Solar Specs 6 solar panels Rated 4V and 100 mA Lamp = “Sun”

14. Reservoir Specs Two fish tanks, a pump and a generator Build generator Don’t know yet generator specs or power production capabilities

15. Possible Extensions  Add wind power  Advanced Peak Power Tracker  More energy efficient loads  Change from DC to AC  Weather Simulations: - Shadowing Effect (cloudy day) - Drought (reservoir runs dry)
