Significant fuel savings and operational efficiencies are some of the benefits of an intelligent power management system that includes multiple energy sources.
The U.S. Army has tested a proof of concept for a smart electrical grid that would support tactical operations in the field. The concept, which was tested last summer, could save potentially billions of dollars in fuel use at remote forward positions. By eliminating the need to transport fuel for generators at such encampments, the new Tactical Operations Smart Grid also carries with it the potential of saving the lives of warfighters.
The smart grid, which takes advantage of multiple off-the-shelf electrical energy technologies, is being developed and tested by the Army’s Research, Development and Engineering Command’s (RDECOM) Communications-Electronics Research Development and Engineering Center (CERDEC). Along with helping set specifications for a future vendor-developed system, data from the tests also are being compiled as part of the Defense Department’s longer-term program of reducing both manpower and fuel use for energy generation.
“These systems are designed to integrate existing military-standard tactical generators managed by portable electric power systems out in the field, providing the ability to intelligently work within a grid operation,” says Michael Zalewski, a project mechanical engineer with CERDEC’s Command, Power and Integration (CPI) directorate. The tactical microgrid is being developed as part of the HI Power program, for Hybrid Intelligent Power. Newly developed digital controllers allow the system to balance electrical production, storage and demand dynamically, he explains, “and by doing this, we’re able to right-size the production of power to the load and demand at that point in time.”
