Abstract
A voltage regulation device includes: an input node configured to receive electrical power from an electrical power source; a primary winding electrically connected to the input node; an output node configured to provide electrical power to a load; a shunt winding electrically connected to the output node; a converter configured to provide a compensation current to the shunt winding; and a control system configured to: determine a harmonic compensation signal based on harmonic frequency data; determine a reactive power compensation signal based on a reactive power set point; and control the converter based on the determined harmonic compensation signal and the determined reactive power compensation signal to produce the output compensation signal. The output compensation signal is configured to reduce the one or more harmonic frequency components in a current that flows in the output node and to control an amount of reactive power at the output node.
