1. A split-load power distribution system comprising:
a distributed energy resource (DER) power source comprising an energy storage device;
an electrical load comprising a first partial load and a second partial load; and
at least one power distribution hub (PDH) comprising at least a first switch configured to operate independent of a second switch of the PDH, wherein the PDH is configured to:
distribute power, via the first switch from a first one of the DER power source via a first busbar or a grid-connected power source via a second busbar, to the first partial load of the electrical load, and isolate the first partial load from the grid-connected power source when the first partial load is receiving power from the DER power source;
distribute power, from a remaining one of the DER power source via the first busbar or the grid-connected power source via the second busbar, to the second partial load of the electrical load, and isolate the second partial load from the grid-connected power source when the second partial load is receiving power from the DER power source; and
in response to a signal that a capacity of the energy storage device of the DER power source is below a pre-determined level, control at least one of the first switch or the second switch to distribute, to the first partial load and the second partial load, via the second busbar, power from the grid-connected power source.
