3. What is Load Management?

4. Load Management is … The customer for the other areas
Design issues related to power to loads
Pulsed Loads
Getting power to the right location so the loads can do their job.
Efficient and Controllable Loads make everyone’s job easier
Controls will play a key role related to interaction between loads and loads and storage
Reconfiguration
PEBB
Intelligent Agents
Sensors

5. Load Management – What is it? ESRDC Renewal Proposal Fall 2007
Objective The objective of this task is to assist the Navy in adapting the best approaches to load management to optimize the cost and effectiveness of future electric ships. It will do this by taking a system based view of shipboard electric power, storage, power distribution, and loads. The focus will be providing information needed to optimize performance and to clarify the relationship between the load management system architecture and emerging technology. The load management system includes the loads themselves, the power distribution system, power storage and conditioning hardware, a control system, and protection and reconfiguration hardware and software.

6. Accomplishments from 2002-2007 related to Load Management
Demonstrated via modeling that large pulsed loads can share stored energy.
Developed technology for load shedding and reconfiguration for damage control and for efficiency optimization.
Developed hardware and software to monitor load behavior and incipient failure in electric ship power systems.
Developed thermal models for major pulsed loads.
Demonstration of a multi-agent system for load management in a DC and AC distribution system.
