Claim:
1. A power distribution system comprising: an ac busbar adapted to carry a variable-frequency ac distribution voltage; an ac generator connected to the ac busbar and having an associated prime mover; at least one additional ac generator connected to the ac busbar, each additional ac generator having an associated additional prime mover; and a power management controller configured to: (i) store load profiles corresponding to the associated prime movers, wherein the load profiles relate output power to speed or frequency for the corresponding prime movers, (ii) detect a change in an electrical load on the ac busbar, (iii) select a new system frequency as the variable-frequency ac distribution voltage on the ac busbar, based on the the change in the electrical load detected and the load profiles stored, (iv) automatically vary the rotational speed of the prime movers based on the change to the electrical load detected based on the load profiles stored, and (v) vary a frequency of the output voltages of each of the ac generators to the ac busbar to match the new system frequency during normal operation of the power distribution system.
