POWER PROCESSING AND ENERGY STORAGE

A power conversion device may perform model-referenced power processing for multiple diverse power nodes. The power conversion device includes interconnects that couple power nodes connection ports to power converters The power converters include a dense tier of power converters sized to correct from varied power flow levels of a defined portion of a population of power nodes to interim power flows in accord with center values for that portion of power nodes. The center values are provided by a model of the power node diversity. The power converters also include a sparse tier. The sparse tier performs power processing to convert from the interim power flows generated by the dense tier to a uniform model-corrected target flow.
