Control system for voltage regulation device

A method of controlling a voltage on a distribution path of an electrical power distribution network that receives electricity from one or more distributed energy resources, the method comprising:

• determining that a voltage on the distribution path is outside of a voltage range;
• determining a time rate of change of a voltage on a distribution path of the electrical power distribution network from at least two voltage measurements, each of the at least two voltage measurements representing the voltage on the distribution path at a different time;
• incrementing a value of a counter associated with a time delay parameter of a voltage regulation device by an amount that is based on the determined time rate of change of the voltage on the distribution path;
• determining whether the value of the counter is equal to or exceeds a maximum counter value;
• if the value of the counter is equal to or exceeds the maximum counter value and the voltage on the distribution path is outside of the voltage range, providing a command signal to a voltage regulation device and resetting the value of the counter to an initial value;
• and
• if the value of the counter is less than the maximum counter value, determining another the time rate of change of the voltage on the distribution path.

A control system for use with a voltage regulation device, the control system comprising:

• one or more electronic processors;
• and
• a computer-readable medium storing instructions that, when executed, cause the one or more electronic processors to:
• determine, from a voltage measurement obtained by the voltage regulation device, that a voltage on a distribution path is outside of a voltage range;
• determine a time rate of change of the voltage on the distribution path, the time rate of change being determined based on at least two samples of the voltage at the distribution path 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.
