Abstract

A system and method for controlling power transfer between a power grid and at least one load. In at least one embodiment, the system includes a controller having a power regulator. The controller obtains grid data related to the power grid. The power regulator of the controller enables or disables and/or increases or decreases the power transfer between the power grid and a first load based at least in part on the obtained grid data and data relating to a power requirement of the first load. The power regulator may be coupled in line between an electric panel connected to the power grid and the first load. The controller may be coupled to the first load through a wiring system of a building. Multiple controllers may be coupled respectively to multiple loads, wherein each controller is configured to control a power transfer between the power grid and a respective load.

Claims

1. A system for controlling power transfer between a power grid and at least one load at premises of a user of the power grid, the system comprising:

a first controller that includes a storage and a first power regulator that is configured to be couplable between a first load and an electric panel that is coupled to the power grid,

wherein the storage contains data relating to one or more power requirements of the first load, and

wherein the first controller is configured to;

obtain grid data relating to a dynamic characteristic of the power grid; and

cause the power regulator to regulate the power transfer between the power grid and the first load based at least in part on the obtained grid data and data retrieved from the storage of the first controller relating to a power requirement of the first load, and

wherein the first controller is further configured to obtain load data relating to a dynamic characteristic of the first load and/or the surroundings of the first load, and cause the first power regulator to regulate the power transfer between the power grid and the first load based on the obtained grid data, the obtained load data, and the data retrieved from the storage of the first controller,

the system further comprising;

a second controller that includes a storage and a power regulator that is configured to be couplable between a second load and the electric panel,

wherein the storage of the second controller contains data relating to one or more power requirements of the second load, and

wherein the second controller is configured to;

obtain grid data relating to a dynamic characteristic of the power grid;

obtain load data relating to a dynamic characteristic of the second load; and

cause the power regulator of the second controller to regulate the power transfer between the power grid and the second load based at least in part on the obtained grid data, the obtained load data, and data retrieved from the storage of the second controller relating to a power requirement of the second load,

wherein the first controller is further configured to transmit data to a power delivery system of the power grid based on one or more of the obtained grid data, the obtained load data relating to a dynamic characteristic of the second load, and data retrieved from the storage of the second controller relating to a power requirement of the second load.

2. The system of claim 1, wherein the second controller is further configured to obtain grid data relating to a dynamic characteristic of the power grid that has been modified based on the data transmitted to the power delivery system of the power grid by the first controller.

3. The system of claim 1, wherein the data transmitted to the power delivery system of the power grid by the first load is indicative of a current or future increase or decrease in power transfer between the power grid and the first load.
