Abstract

A system and method for synchronizing a frequency of plurality of variable frequency generators with a variable frequency load over a variable frequency bus independent of a frequency conversion stage. A synchronization controller is configured to determine an optimal bus frequency of the variable frequency bus based on at least one power demand requirement of the variable frequency load operatively connected to the variable frequency bus. With the optimal frequency, an available power range supplied by the plurality of variable frequency gensets at the optimal bus frequency can be determined. The synchronization controller then asymmetrically loads the variable frequency load to the plurality variable frequency gensets at the optimal bus frequency based on the operating range of each variable frequency genset and recursively updates the optimal bus frequency based on operational statistics of the asymmetrically loaded variable frequency gensets.
