Abstract: A system is provided. The system includes a plurality of uninterruptible power supplies (UPSs), a ring bus, at least one load electrically coupled to the plurality of UPSs and the ring bus, and a controller communicatively coupled to the plurality of UPSs. The controller is configured to calculate a phase angle for each UPS of the plurality of UPSs, wherein the phase angle is calculated relative to a common reference angle, and control operation of each UPS based on the respective calculated phase angles.
