A plurality of generator sets, or gensets, each including an electrical generator operatively associated with a prime mover, are arranged in parallel to generate electrical power for an isolated electrical load.

A control strategy is configured to allocated real power demands of the electrical load among the plurality of gensets in accordance with the asymmetric load sharing method. The control strategy may account for the reactive power portions of the electrical load in addition to the real power portions.
