D-VAR VVO™ optimizes power electric grids at the distribution level, providing the essential flexibility and responsiveness needed as electric grids evolve towards a distributed generation (DG) architecture. DG refers to electricity generation within the distribution system itself, as opposed to the stream of electricity generated from centralized power plants, which is delivered to substations via the transmission grid and then delivered to customers via the distribution grid. Sources of DG include biomass, wind turbines, solar (photovoltaic, PV) panels and electric vehicles.
