Abstract

A control system (300) allows recognized standard premise electrical outlets, for example NEMA, CEE and BS, among others to be remotely monitored and/or controlled, for example, to intelligently execute blackouts or brownouts or to otherwise remotely control electrical devices. The system (300) includes a number of smart receptacles (302) that communicate with a local controller (304), e.g., via power lines using the TCP/IP protocol. The local controller (304), in turn, communicates with a remote controller (308) via the internet.

Claims

1-28. -28. (canceled)

29. A power distribution system, comprising:

a power grid for distributing power over a geographic distribution area;

one or more grid controllers for controlling distribution of power across said power grid; and

a number of customer premises controllers, each for controlling delivery of power within a particular customer premises based on communication between said customer premises controller and at least one of said grid controllers.

30. A system as set forth in claim 29, wherein said defined polices include local policies specific to said customer premises.

31. A system as set forth in claim 29, wherein said defined policies include grid policies communicated from at least one of said grid controllers.

32. A system as set forth in claim 31, wherein said grid policies are executed in accordance with local policies.

33. A system as set forth in claim 29, wherein said customer premises controllers are associated with individual electrical receptacles of said customer premises.

34. A power distribution method, comprising:

identifying an over-capacity condition with respect to at least a portion of a power distribution grid, said over-capacity situation potentially requiring reduction of power provided to standard residential and business customers; and

addressing said over-capacity condition by controlling power distribution at a level finer than the finest distribution subdivision of said power distribution grid servicing said standard residential and commercial customers.

35. A method as set forth in claim 34, wherein said step of addressing comprises one of reducing and interrupting power delivered to a subset less than the whole of the set of receptacles of a single customer premises.

36. A method for use in controlling transmission of communication signals across a power line, comprising the steps of:

defining a communications domain including at least a first device and a second device for communicating over a power line;

providing a transmitter for inserting communication signals onto said power line; and

providing an isolation element for substantially preventing transmission of said communication signals outside of said communications domain.

37. A method as set forth in claim 36, further comprising the step of operating said isolation element to cancel said communications signals.

38. A method as set forth in claim 36, further comprising the step of operating said isolation element to attenuate said communications signals.

39. An apparatus for use in controlling transmission of communication signals across a power line, comprising:

a first device and a second device, each disposed within a communications domain, for communicating over a power line;

a transmitter for inserting communication signals onto said power line; and

an isolation element for substantially preventing transmission of said communication signals outside of said communication domain.

40. An apparatus as set forth in claim 39, wherein said isolation element comprises a signal canceller.

41. An apparatus as set forth in claim 39, wherein said isolation element comprises a filter for filtering a power signal on a frequency dependent basis.
