Intelligence for Electric Grids

2. Program Overview - Scope
• Develop and field an innovative combination of advanced
power controls and intelligent power distribution reducing fuel
consumption while allowing systems to seamlessly operate
independently.
• Produce, manufacture, test and deliver prototype Intelligent
Power Distribution (IPD) items, including:
• Two (2) IPC-in-the-wire for generators
• Two (2) Intelligent Phase Balancing PDUs (IPMDS)
• Two (2) IPC-in-the-wire for two (2) 5-ton ECUs

3. Program Overview - Objectives
1. Enhanced Military Capability and System Cost Reduction
• Reduced fuel consumption and generator run time
• Reduced heat buildup, generator damage and maintenance requirements through
dispatch optimization and phase balancing
• Sound abatement
• Reduced system weight
2. Accelerates Military Development Capability
• Plug-and-Play capability
• Automatic reconfiguration
• Improved system flexibility and simplicity
• Advanced monitoring and future capability for prognostics and diagnostics
3. Acquisition Development Cost Reduction
• Retrofit existing fielded equipment
• Simplify manufacturing to minimize field maintenance costs

ATO Issued
IPERC has implemented
three installation microgrids
for the SPIDERS program,
sponsored by the US
Department of Defense in
collaboration with the
Department of Energy and
the Department of
Homeland Security. The
program focuses on
protecting mission-critical
loads and bolstering energy
efficiency.
