Ever wondered how much electric energy the world consumes or how much energy is lost on its way from power plants to end user customers? Have you wondered how much energy could be saved or greenhouse gas emissions could be cut by reducing energy losses by only a small amount? With the proper implementation of technology and a concerted effort we can reduce electric energy losses and the demands made on electric distribution systems. A wide panorama of technology already exists to achieve that objective. Voltage and VAR Optimization (VVO) is the latest addition to those applications. But unlike the traditional approach using uncoordinated local controls, VVO uses real-time information and online system modeling to provide optimized and coordinated control for unbalanced distribution networks with discrete controls.
