Abstract

Automated identification of components connected within a power grid is facilitated by: obtaining by one component of the power grid a request to broadcast a power-connected beacon identifying, at least in part, the one component of the power grid; and responsive to the request, automatically broadcasting by the one component the power-connected beacon into the power grid by superimposing the beacon onto an energized power line to identify that the one component is electrically connected to the power grid. In one embodiment, the power grid includes one or more stand-alone sub-grids, and the one component is a load component, or a distribution component, or a power-supply component of one stand-alone sub-grid of the power grid, and the obtaining is subsequent to a reconfiguration of the power grid, wherein one or more stand-alone sub-grids in the power grid are modified.

4. The method of claim 3, wherein the reconfiguration of the power grid is a dynamic reconfiguration of the power grid, wherein the one or more stand-alone sub-grids of the at least one stand-alone sub-grid of the power grid are automatically modified without interrupting power to the power grid, and without shedding load components from the power grid.

5. The method of claim 2, wherein the one component is a load component of the at least one load component of the one stand-alone sub-grid, and wherein the method further comprises, prior to the automatically broadcasting, obtaining by the at least one power supply component of the one stand-alone sub-grid an indication of an anticipated power-connected beacon broadcast on the energized power line of the power grid, and wherein the indication facilitates detection by the at least one power supply component of the power-connected beacon broadcast by the load component of the one stand-alone sub-grid.

6. The method of claim 2, wherein the one component is a load component of the at least one load component of the one stand-alone sub-grid, and the obtaining comprises receiving by the load component the request from a controller associated with the power grid, and wherein the controller sequentially sends the request to broadcast the power-connected beacon to a plurality of load components coupled to the power grid, the plurality of load components comprising the at least one load component of the one stand-alone sub-grid.

7. The method of claim 6, wherein, prior to the automatically broadcasting, the controller further sends an indication of an anticipated power-connected beacon broadcast on the energized power line of the power grid to a plurality of power supply components coupled to the power grid, the plurality of power supply components comprising the at least one power supply component of the one stand-alone sub-grid.

8. The method of claim 6, wherein the controller is associated with the at least one power supply component of the one stand-alone sub-grid of the at least one stand-alone sub-grid of the power grid, and the controller sends the request subsequent to a dynamic reconfiguration of the power grid, wherein one or more stand-alone sub-grids of the at least one stand-alone sub-grid of the power grid are automatically modified.

9. The method of claim 6, further comprising inquiring, by the controller, whether the at least one power supply component of the one stand-alone sub-grid received the power-connected beacon superimposed onto the energized power line of the power grid by the load component, and based in part thereon, the controller automatically determines which components of the plurality of load components and a plurality of power supply components coupled to the power grid are electrically connected in the one stand-alone sub-grid.

10.
