Optimizing Load Tap Changer and Voltage Regulator Control in Distribution to Stabilize Voltage with DER Penetration

The impact of distributed energy resources (DER), specifically for solar and wind power, continues to be challenging for many utilities with increased DER penetration. Problems associated with DER include: reverse power conditions, fast and unpredictable voltage fluctuations, excessive on-load tap changer transformer (OLTT) operations, and “hunting” conflicts between OLTTs, distribution capacitor banks, and active VAR DER. In this podcast, we discuss “smart control” methodologies that help mitigate these issues—without costly communication systems—while fostering volt/VAR optimization, minimizing voltage constrained hosting barriers, and as a signal for controlling VAR and watt output.
