Abstract: A system for an electrical power distribution network receives electricity from one or more distributed energy resources. The system includes a voltage regulation device configured to maintain a voltage in the electrical power distribution network within a range of voltages, the voltage regulation device including a voltage sampling module configured to obtain an indication of a voltage in the electrical power distribution network; and a control system coupled to the voltage regulation device, the control system configured to: determine a metric related to a time rate of change of the voltage in the power distribution network based on at least two samples of the voltage in the electrical power distribution network obtained at different times; and change at least one operating parameter and/or an operating mode of the voltage regulation device based on the determined rate of change of the voltage.

Abstract: A system having voltage regulator bypass means provides a means for preventing a voltage regulator to be bypassed in a power system when the difference between a load side voltage of the voltage regulator and a source side voltage of the voltage regulator is not below a certain threshold or substantially small. A voltage regulator controller can also prevent the voltage regulator from being bypassed when a tap changer of the voltage regulator is not in a neutral position.
