Various energy sources
Connection to main power grid
Capable of parallel, independent operation
Single home, community, commercial building
Building blocks of smarter grid What is a Microgrid? Energy Storage
Batteries, EV storage
Wind, Solar generation effectiveness
Avg. US household: 930 kWh/month
6.44 kW, 643 sq. ft. (2000 sq. ft. home)
$30k after subsidies Technical Issues
Wind: Central plains US 
Renewable resource location
Solar: Southwest US  Environmental Considerations IEEE 1547 Standard 
Distributed resources and electric power systems
Series Standards 1547.1 – 1547.6
Monitoring and information exchange
Design, operation and integration
Additional requirements 
Islanding Regulations Diesel generators 
Assets and installation $350/kW
Fuel cost $4.00/gallon
Total cost estimate $2,250 + $100/mo
Solar PV 
Assets and installation $3500/kW
Total cost estimate $22,500
Assets and installation $6,000 - $45,000
$650/kWh Economic Considerations ,  Energy Management
Lack of smart meters, HAN
“Big Utilities” resistance
Subsidy Support: 30% Federal Barriers Microgrids open up possibilities for dramatic change in the structure of the energy system
Help develop the smart grid
Active demand management
response to electricity price
reduce the peak demands on the network
lead to large scale energy savings Summary “Island” from the larger grid to maintain power supply in an emergency
Enhance grid reliability by reducing demand on transmission and distribution network
Potential to reducing greenhouse gas (GHG) emissions from buildings  Summary Economic and institutional issues have to be addressed to make it happen
Requires a supportive public
Supportive policies and regulatory structure
Climate change is now a major element of energy policy it will increase the need for microgrids
As technology matures and cost decreases microgrids will become cost-competitive 
Meet local power demands Future Development of Microgrids ,  , ,  Inflexible, Vulnerable, Non-transparent
Increasing incorporation of renewables
Expansion of grid by utilities not economical long-term
Levelized Cost of Energy! Problems with the current grid
