Abstract
A home energy management system (HEMS) includes a controller configured to monitor an electrical parameter on a line coupled to a distributed energy resource (DER), and an inverter electrically connected to the line and operable to generate an alternating current (AC) voltage on the line. The controller is configured to, after a DER shutdown trigger, and the DER producing an output after an interval, command the inverter to increase the AC voltage on the line to a level that induces a shutdown response from the DER.
Claims19
A home energy management system (HEMS), comprising:
- a controller configured to monitor a line coupled to a distributed energy resource (DER);
- and
- an inverter electrically connected to the line and operable to generate an alternating current (AC) voltage on the line, wherein the controller is further configured to, after a DER shutdown trigger and the DER producing an output after an interval, command the inverter to increase the AC voltage on the line to a level that induces a shutdown response from the DER.
A home energy system, comprising:
- a distributed energy resource (DER) configured to output electrical power for an alternating current (AC) line and to cease outputting the electrical power when a voltage on the AC line exceeds a value;
- an inverter electrically connected to the AC line and operable to generate an AC voltage on the AC line;
- and
- a controller operatively coupled to the inverter and configured to command the inverter to increase the AC voltage on the AC line such that the distributed energy resource ceases the outputting.
A method of operating a home energy system, comprising:
- in response to a distributed energy resource (DER) not discontinuing a power output to an AC line within an interval beginning with a condition under which the DER is expected to discontinue the power output, increasing, by an inverter electrically coupled to the AC line, a voltage on the AC line.
