1. An electrical power distribution system for converting and distributing electrical power to local loads within a vehicle, comprising:
at least one generator providing high voltage AC (HVAC) power;
a primary power panel for receiving the HVAC power from the generator;
a plurality of distribution conversion units located throughout the vehicle, wherein the plurality of distribution conversion units convert the HVAC power from the primary power panel into medium voltage AC (MVAC) power and low voltage DC (LVDC) power for consumption by the local loads within the vehicle;
a plurality of HVAC distribution feeder lines, wherein each HVAC distribution feeder line connects the primary power panel to one of the plurality of distribution conversion units;
a bi-directional power converter for converting the HVAC power into LVDC power and also converting LVDC power into HVAC power; and
an energy storage device in communication with the bi-directional power converter, wherein the energy storage device provides HVAC power and MVAC power in response to a loss of generator power.
