Abstract

An approach for enabling identification of different types and sources of power being distributed over an electrical power grid is disclosed. An energy management module determines one or more power flows transmitted over at least one electrical power grid. The energy management module then causes a encoding of one or more identification signals into the one or more power flows. The one or more identification signals distinguish the one or more power flows from one or more other power flows transmitted over the at least one electrical power grid.

Claims

1. A method comprising facilitating a processing of and/or processing (1) data and/or (2) information and/or (3) at least one signal, the (1) data and/or (2) information and/or (3) at least one signal based, at least in part, on the following:

at least one determination of one or more power flows transmitted over at least one electrical power grid; and

an encoding of one or more identification signals into the one or more power flows,

wherein the one or more identification signals, at least in part, distinguish the one or more power flows from one or more other power flows transmitted over the at least one electrical power grid.

2. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination to cause, at least in part, the encoding of the one or more identification signals using at least one signal modulation mechanism that provides, at least in part, an orthogonality, a pseudorandomness, or a combination thereof of the one or more identification signals.

3. A method of claim 2, wherein the at least one signal modulation mechanism includes, at least in part, a code division multiple access (CDMA) mechanism.

4. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

a generation of the one or more identification signals based, at least in part, on one or more sources, related metadata, or a combination thereof associated with the one or more power flows, the at least one electrical power grid, or a combination thereof.

5. A method of claim 4, wherein the related metadata thereof include, at least in part, one or more energy types, one or more energy producer types, one or more environmental impacts, one or more brands associated with the one or more sources, or a combination thereof

6. A method of claim 1, wherein the at least one electrical power grid comprises, at least in part, one or more encoding repeaters;

wherein the one or more encoding repeaters re-encode the one or more identification signals across one or more components of the at least one electrical power grid; and

wherein the one or more components include, at least in part, one or more transformers.

7. A method comprising facilitating a processing of and/or processing (1) data and/or (2) information and/or (3) at least one signal, the (1) data and/or (2) information and/or (3) at least one signal based, at least in part, on the following:

a reception of one or more power flows transmitted over at least one electrical power grid;

a decoding of one or more identification signals from the one or more power flows; and

a processing of the one or more identification signals to cause, at least in part, a selection, a use, a filtering, or a combination thereof of the one or more power flows.

8. A method of claim 7, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

9. A method of claim 8, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

a generation of one or more reports associated with the selection, the use, the filtering, or a combination thereof of the one or more power flows based, at least in part, on the one or more sources, the related metadata, or a combination thereof and

a transmission of the one or more reports to one or more entities associated with the one or more sources, the at least one electrical power grid, or a combination thereof

10. A method of claim 7, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:
