Mission Statement
The mission of SimBoulder is
to demonstrate the effective
integration of renewable energy
power sources
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
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
Function Specifications
Boulder
 Pop. = 90,000
 Power consumption =
200 MW
 Size = 30 square miles
 Time = 24 hrs
SimBoulder
• Population = 0
• Power consumption =
2W
• Size = 8 square feet
• Time = 2.4 min
Ratio
Power consumption & Area = 100,000,000:1
Time = 600 : 1
Functional Specifications
Division of Energy
•Residential – 22%
•Industrial – 32%
•Transportation – 28%
•Commercial – 18%
Functional Specifications
Solar Specs
• 6 solar panels
• Rated 4V and 100 mA
• Lamp = “Sun”
Reservoir Specs
• Two fish tanks, a pump and a generator
• Build generator
• Don’t know yet generator specs or power
production capabilities
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)

Project Timeline
Risk Analysis
• Insufficient power generation from renewable sources
– Increase percentage of power generated from power plant
• Availability of generator turbine of size and efficiency
– Build our own generator
• Interference of noise and magnetic
– Shield circuits with appropriate capacitors
– Power trace layout on circuit board
