Distribution Feeder Voltage Regulation Control

Step voltage regulators are the workhorse of distribution feeders for maintaining the voltage at every customer's meter to be within the ANSI standards. A step voltage regulator can be viewed as a tap-changing autotransformer. This paper will apply a model of the step voltage regulator. The IEEE 13 Node Test Feeders will be used to demonstrate how the regulator is controlled in order to maintain the desired voltage for full-, light-, and future-load conditions. The coordination of step voltage regulators with shunt capacitors will be included.
