Energy storage systems play a vital role in electric utility infrastructure and remote power systems by providing multiple technical and economic benefits such as improved asset utilization, consumer flexibility and cost control, and increased value of variable energy sources such as from photovoltaic and wind energy. The DOE Energy Storage Program leads a worldwide effort in addressing energy issues through energy storage R&D for grid-tied and off-grid systems throughout the United States, including on Native American tribal lands. Power conversion systems (PCS) are a key enabling technology for energy storage. In a grid-tied energy storage system, the PCS controls the power supplied to and absorbed from the grid, simultaneously optimizing energy storage device performance, and maintaining grid stability. In addition to energy storage and PCS R&D, the Energy Storage Program is also focused on addressing energy access issues in disadvantage tribal communities and promoting tribal sovereignty. This presentation will provide a background on grid-tied energy storage and power electronics R&D and show examples of energy storage and power electronic benefits to tribal communities. The presentation will begin at 2 PM in location and Dr. Atcitty will be in the venue until 4 PM. Save the date and tell your friends and stop by location to learn more about electrical energy in tribal communities. Anyone is welcome to attend this event, and no one is required RSVP.
