Claim Text:
1. A method for maximum deviation multi-phase operation, comprising: setting, by a voltage regulator controller of a plurality of voltage regulator controllers that are communicatively coupled to each other via a communications link, a low boundary value of a maximum deviation window based on a first highest tap position of a plurality of tap changers and a user-defined maximum deviation value by subtracting the user-defined maximum deviation value from the first highest tap position; setting, by the voltage regulator controller, a high boundary value of the maximum deviation window based on a first lowest tap position of the plurality of tap changers and the user-defined maximum deviation value by adding the user-defined maximum deviation value to the first lowest tap position; and independently regulating, by the plurality of voltage regulator controllers, a respective plurality of voltages of a respective plurality of voltage regulators based on the tap positions of the plurality of tap changers.
