Application of Power Electronics LV Power Regulators in a Utility Distribution System Utilities are developing new ways to manage the connection of increasing amounts of distributed generation (DG) on the electric grid. Among other issues, DG can lead to high voltage and other powerquality problems. This paper describes a field trial by Greater Sudbury Hydro of a new low voltage control device, the LV-IPR. The device controls voltage directly by way of a series voltage injection, as well as providing reactive and harmonic compensation, with a unified power flow controller [1] architecture. The device is successfully regulating the voltage at the test site, which had been experiencing high voltage excursions.
