This paper focuses on controlling reactive power output using passive filters capable of supplying reactive power to mitigate overvoltage conditions in distributed power systems, aiming to enhance voltage stability. In a case study, the IEEE-34 bus model was utilized, and changes in voltage at various locations within the distribution network were observed after integrated photovoltaic as a inverter based resource. Using a Python-based COM interface integrated with OpenDSS, the reactive power output was regulated, and in response to changes in reactive power output, the passive filter was readjusted. As this paper primarily emphasizes reactive power, the effects of harmonic removal were not emphasized. To validate the control approach, voltage fluctuations at all buses were monitored within OpenDSS, confirming the results and demonstrating the effectiveness of this method.
