Abstract

Some embodiments relate to a power generation system which includes a bus and a first single-phase synchronous generator that may provide a voltage output to the bus. A first generator controller operates the first single-phase synchronous generator. The power generation system further includes a second single-phase synchronous generator that may provide a voltage output to the bus. A second single-phase synchronous generator controller operates the second single-phase synchronous generator. The power generation system further includes a communication module that exchanges data with at least one of the first generator controller and the second generator controller such that the first generator single-phase synchronous generator and the second single-phase synchronous generator are able to simultaneously supply a voltage and current output to the bus.
