Claim:
1. A system of controlling active and reactive power flows between a first AC source and a second AC source, comprising: a transformer comprising a first set of windings and a second set of windings, the first set of windings of the transformer configured to be coupled to a first line-neutral voltage of a first phase, the first line-neutral voltage corresponding to a first AC source; and a power converter having an input and an output, the input of the power converter configured to be coupled to a second voltage corresponding to a second phase and a third voltage corresponding to a third phase, the output of the power converter coupled to the second set of windings of the transformer; wherein the power converter is configured to inject an adjustable voltage in series with a voltage across the second set of windings of the transformer to create a second line-neutral voltage, the second line-neutral voltage corresponding to a second AC source.
