Traditional volt/VAR (volt amps reactive) management technologies have been used by the power industry for more than 30 years to reduce line losses and increase grid efficiency. In addition, voltage and VAR optimization (VVO) technologies use real-time information and online system modeling to provide optimized and coordinated control. As the number of intermittent renewable sources (e.g., solar and wind) increases, however, so does the complexity of the controls. VVO and other power electronics–based technologies can mitigate rapid and large voltage fluctuations that result from high penetration of distributed generation.
