1. A device including:
multiple power store connection ports including:
a first connection port to support a first power flow range, the first power flow range spanning one or more first expected power flow levels for a first defined portion of a group of power stores; and
a second connection port to support a second power flow range, the second power flow range spanning one or more second expected power flow levels for a second defined portion of the group of power stores; and
a dense converter tier coupled to the multiple power store connection ports, the dense converter tier including:
a first dense tier power converter coupled to at least the first connection port, the first dense tier power converter configured to convert from within the first power flow range to a first interim power flow, a level of the first interim power flow selected based on a diversity model for the group of power stores; and
a second dense tier power converter coupled at least to the second connection port, the second dense tier power converter configured to convert from within the second power flow range to a second interim power flow, a level of the second interim power flow selected based on the diversity model for the group of power stores; and
a sparse converter tier coupled to the multiple power store connection ports via the dense converter tier, the sparse converter tier a sparse tier power converter configured to convert a combined power flow to a uniform model-corrected target, the combined power flow including at least a portion of each of the first and second interim power flows.
