Abstract
Systems and methods for managing loads on a power grid are provided. The load control system includes one or more energy sources connected to a common bus and a first device connected in series between the common bus and a first load. The first device may be an automatic transfer switch. The first device may include switching hardware configured to connect and disconnect the first load from the common bus and a load control circuit configured to cause the first load to disconnect from the common bus after a pre-determined amount of time detecting a trigger.
Claims20
A device comprising:
- a first terminal configured to connect to an output of one or more energy sources;
- a second terminal configured to connect to a load;
- switching hardware configured to connect the first terminal to the second terminal;
- and
- a load control circuit configured to:
- detect a condition on the first terminal;
- and
- in response to detecting the condition for a pre-determined amount of time, cause the switching hardware to electrically disconnect the first terminal from the second terminal.
A system comprising:
- one or more energy sources connected to a common bus, the one or more energy sources configured to output energy to the common bus;
- a first automatic transfer switch (ATS) connected to the common bus and a first load, the first ATS comprising:
- switching hardware;
- and
- a load control circuit, the load control circuit configured to:
- detect a trigger on the common bus, the trigger indicative of a condition;
- and
- in response to detecting the trigger for a first pre-determined amount of time, cause the first load to electrically disconnect from the common bus;
- and
- a second ATS connected to the common bus and a second load, the second ATS comprising:
- switching hardware;
- and
- a load control circuit, the load control circuit configured to:
- detect the trigger on the common bus;
- and
- in response to detecting the trigger for a second pre-determined amount of time, cause the second load to electrically disconnect from the common bus.
A method of controlling load conditions on a power grid comprising:
- detecting, via a first device, a condition on a common bus of a power grid, wherein the first device is connected in series to the common bus and a first load;
- and
- in response to detecting the condition for a pre-determined amount of time, disconnecting, via the first device, the first load from the common bus.
