Abstract

A smart-grid communication system including a plurality of receptacles and a power management gateway in electrical communication with each of the plurality of receptacles is presented. Each of the power modules of the plurality of receptacles provides power usage information to the power management gateway. Also, the power usage information is transmitted via a first communication means to the power management gateway and the power management gateway transmits the information via a second communication means to one or more external communications sources.

Claims

1-50. -50. (canceled)

51. A smart-grid communication system comprising:

a plurality of receptacles, each receptacle including a front plate, a back plate, at least one outlet, and a power module located within the receptacle; and

one or more power management gateways in bidirectional communication with the plurality of receptacles;

wherein the power module of each of the plurality of receptacles includes at least one sensor and a processor to collect and communicate energy consumption information to the one or more power management gateways.

52. The communication system according to claim 51, wherein the at least one sensor is configured for measuring current and voltage.

53. The communication system according to claim 51, wherein the processor is configured for collecting, analyzing, and communicating the energy consumption information.

54. The communication system according to claim 51, wherein the power module of each of the plurality of receptacles is configured to include notification means.

55. The communication system according to claim 51, wherein the power module of each of the plurality of receptacles is configured to measure and control electricity consumption.

56. The communication system according to claim 51, wherein the power module of each of the plurality of receptacles is configured to control at least one parameter selected from the following:

voltage present in an AC line, AC current consumed by a load, wattage consumed by the load, apparent power consumed by the load, a power factor, and kilowatt-hours consumed by the load.

57. The communication system according to claim 51, wherein the one or more power management gateways are connected to one or more smart-grid servers, the one or more smart-grid servers being connected to one or more external smart hubs.

58. The communication system according to claim 51, wherein the one or more power management gateways are configured to be controlled by a single central power management gateway.

59. The communication system according to claim 51, wherein the plurality of receptacles are configured to be separated into a plurality of subsets, each subset collectively managed by the one or more power management gateways.

60. The communication system according to claim 51, further including a converter configured to enable communication between the one or more power management gateways and a plurality of networks.

61. The communication system according to claim 51, further including a converter configured to enable communication between the plurality of receptacles and the one or more power management gateways.

62. The communication system according to claim 51, wherein each of the one or more power management gateways is configured to rank the plurality of receptacles connected thereto based on at least one criterion.

63. The communication system according to claim 51, wherein external power generating devices are configured to provide power to the communication system, the communication system reconfigures power usage of the plurality of receptacles based on the amount of the external power received from the external power generating devices.

64. The communication system according to claim 51, wherein each of the plurality of receptacles is configured to be controlled from a remote location.

65. The communication system according to claim 51, wherein each of the plurality of receptacles is configured to be associated with an Internet Protocol (IP) address for bidirectional communication with the one or more power management gateways.

66. A receptacle comprising:

a front plate, a back plate, at least one outlet, a meter unit; and

at least one sensor located within the receptacle for measuring an electrical usage parameter;

wherein the meter unit is configured to collect and communicate the measured electrical usage parameter to one or more power management gateways.

67. The receptacle according to claim 66, wherein the meter unit of the receptacle is configured for measuring current and voltage via the at least one sensor.

68. The receptacle according to claim 66, wherein the meter unit of the receptacle is configured to include a processor for collecting, analyzing, and communicating the energy consumption information.

69. The receptacle according to claim 66, wherein the meter unit of the receptacle is configured to measure and control electricity consumption.

70. The receptacle according to claim 66, wherein the meter unit of the receptacle is configured to control at least one parameter selected from the following:

voltage present in an AC line, AC current consumed by a load, wattage consumed by the load, apparent power consumed by the load, a power factor, and kilowatt-hours consumed by the load.

71. The receptacle according to claim 66, wherein the receptacle includes a display unit for displaying information related to the receptacle in communication with the one or more power management gateways.

72. The receptacle according to claim 71, wherein the display unit includes one or more audio indicators, one or more visual indicators and/or a display screen.

73. The receptacle according to claim 66, wherein historical usage and cost data is extracted from a memory unit included in the receptacle.

74. The receptacle according to claim 66, wherein the receptacle is configured to be controlled from a remote location.
