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.
