Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company, for the United States Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000.
• Southwest Army base served by two feeders
• May 2002 forest fire took out both feeders
• Base down for 16 hours
– Est. cost $3M
– Loss of mission capability
• During hurricanes in 2005 base power outages of 3 weeks
• Southwest semiconductor plant served by two feeders
• Forest fire 2005 takes out both feeders
• Chip fab shuts down for 3 months
• High-value customers cancel orders due to delay
• Economic loss forces plant to shut down permanently
• Competitor with on-site generation and storage was down less than one day
With distributed generation and storage, electric power can be provided when the grid is down

• Major Issues and Challenges
– Future electric grid incorporating extensive distributed generation will require more complex system control and integration to ensure energy safety, security, and reliability including:
• Real-time or near real-time assessment, control, and optimization of extensive distributed generation resources while maintaining power quantity and quality
• Significantly improved control system cyber security
• Improved intermediate and large-scale energy storage technologies to maintain renewable energy delivery reliability
• Bidirectional power flow requires new advanced safety standards for distributed generation connection and operation in grid-tied and islanded modes
• System control and hardware design and operational standards scalable for micro, intermediate, and utility-scale grid applications
• Extensive testing and monitoring of control and operations approaches to verify cost and performance to reduce operational and safety risks to utilities and the public

Objective
To address current shortcomings of power reliability and security, Sandia is investigating advanced microgrid approaches to locate more secure and robust distributed energy generation and storage sources near loads as a way to better manage power generation and to improve overall power reliability and security. Microgrids are equally applicable to military, industrial, and utility distribution applications.

Technical Scope
Sandia’s microgrid research utilizes smart grid technologies to enable distributed energy generation and storage to be operated in both
‘grid-tied and ‘islanded’ modes. This enables energy demand/response management, increased use of distributed and renewable energy technologies, and improved cost-effectiveness, and reliability. The program leverages DoD, DOE, and industry funding to develop and evaluate smart grid technologies at DoD and other sites and testbeds. December 2008

Helping to accelerate Commercial Smart Grid Testing
Consequence modeling shows that significant reliability and security improvements available with advanced microgrids
• Automated microgrids show great flexibility - control, safety, and cyber security issues are not insurmountable
• Can improve energy reliability in remote areas and on congested feeders
Advanced microgrids able to operate “islanded” and “grid – tied” can greatly improve the ROI of distributed energy
• Demand/response and ancillary services opportunities can be significant
• Combined cooling, heat, and power (CCHP) have large potential
Multiple microgrids are often the best energy reliability approach at bases (coupling/networking can be even more beneficial and cost effective)

• Energy Surety Microgrids are an example of energy risk management - matching energy supply reliability and security within a community energy assurance context
• Consequence analysis and assessment can illustrate the effect of energy improvements on critical mission capability
– Different from stating 9’s of reliability – which does not factor in the erosion of critical energy needs for extended outages
• Supports energy assurance for extended operations as needed during either loss of utility power or as a stand alone small distributed energy grid
• Permits integration of renewables and storage into power supply infrastructure for ‘islanded’ and ‘grid-tied’ operations to increase electric power system safety and reliability to meet community critical energy needs
