Volt-VAR Optimization (VVO)

A technique for reducing the amount of energy waste or over provisioning on the distribution grid. VVO is a process used to actively manage voltage levels and reactive power on distribution circuits in order to reduce energy losses, improve reliability, and power quality. VVO is typically achieved through the use of real-time information and controls that activate capacitor banks, voltage regulators, and transformer load-tap changers, and, in some cases, distributed generation to adjust voltage and VAR levels on the primary and secondary distribution circuits.
