The term 'VVC' stands for Volt/VAR control and refers to the technique of using voltage regulating devices and reactive power controls to maintain voltage levels within the accepted ranges at all points of the distribution system under all loading conditions. Modern software techniques and the progress on communication technologies allow nowadays achieving these goals and therefore the service quality has improved remarkably in most utilities throughout the world.
