Mitigation of Distribution Voltage Violations Using Single-Phase Residential Static VAr Compensators

An alternative method to support the voltage at the end of a distribution feeder using residential static VAR compensators (RSVCs) is presented. The distribution feeder and the RSVCs were modeled using OpenDSS and validated by comparing the results of measured data with the output of the model. Results show that the use of RSVCs on the low side of the service transformers is an efficient way to mitigate low- and high-voltage violations in the distribution feeder. During a one-month evaluation of the system, the results show that the use of RSVCs was able to eliminate all voltage violations below 113 V and it reduced the number of voltage violations under 114 V by 88%.
