Abstract

A method and system for reducing demand on a power grid through demand side management includes receiving assigned priorities from a customer for smart appliances and for appliances plugged into sockets of one or more smart plugs of the customer, the assigned priorities indicative of a customer-preferred sequence for disconnection of, or adjustment of power to, the appliances from the power grid. The system determines whether to disconnect or adjust power to at least one of the appliances of the customer; and selects at least one of the appliances according to the assigned priorities to reduce demand on the power grid. The system sends one or more commands, the one or more commands indicative to the one or more smart plugs to disconnect or adjust power to the selected at least one of the appliances based on selecting at least one of the appliances.

First claim

We claim:

1. A device comprising:
a plurality of sensors configured to dynamically sense a plurality of power related operational parameters indicative of operation of respective customer appliances;
a smart plug comprising a plurality of sockets, the plurality of sensors coupled with respective sockets,
the smart plug further comprising a network interface configured to selectively communicate data comprising power related operational parameters received via the sockets over a first communication path or a second communication path, the first communication path via a customer home network, a customer router, and a public network for receipt by a smart plug headend at a central utility data center, and the second communication path via a smart meter through which the data is transmitted directly to the smart plug headend at the central utility data center over a dedicated smart grid infrastructure communication network; and
a processor configured to execute commands received over the first communication path or over the second communication path, the commands instructing the smart plug to selectively adjust power to the respective customer appliances.

2. The device of claim 1 , wherein the commands received over the first communication path or over the second communication path are indicative of a priority level, and the processor is configured to determine respective customer appliances for which power should be selectively adjusted based on the priority level associated with the respective customer appliances.

3. The device of claim 1 , wherein the sockets of the smart plug are each assigned a respective priority, and the respective customer appliances are supplied power from a respective socket of the smart plug in accordance with the respective priority of the respective socket.

4. The device of claim 1 , wherein the processor is further configured to calculate a consumed power and a power factor of a customer appliance based on power related operational parameters indicative of operation of the customer appliance.

5. The device of claim 1 , further comprising a smart gateway configured to communicate with the customer home network over the first communication path, the smart gateway operable as a network gateway for the smart plug and other smart plugs included in the customer home network.

6. The device of claim 1 , wherein the processor is further configured to identify corresponding sockets to which the one or more respective appliances to be disconnected or adjusted are connected, and the processor further configured to disconnect power to the corresponding sockets of appliances identified for disconnection by actuation of a relay or switch connected to the corresponding sockets of appliances to be disconnected; and the processor further configured to transmit a setpoint adjustment signal to a controller of corresponding sockets of appliances identified for adjustment of power.

7. The device of claim 1 , wherein a sensor included among the plurality of sensors is configured to sense power related operational parameters in a form of environmental data indicative of an environment in which the smart plug resides, the environmental data used in establishing the commands.

8. A method comprising:
dynamically sensing a plurality of power related operational parameters from a plurality of sensors, the plurality of power related operational parameters indicative of operation of respective customer appliances;
transmitting data comprising the plurality of power related operational parameters over a first communication path or a second communication path to a central utility data center, the first communication path including a customer home network and router through which the data is transmitted over a public network, and the second communication path including a smart meter through which the data is transmitted directly to the central utility data center over a dedicated smart grid infrastructure communication network;
receiving from the central utility data center over the first communication path and the customer home network or over the second communication path and the dedicated smart grid infrastructure communication network a command to selectively control operation of the respective customer appliances according to a priority associated with the respective customer appliances;
executing the command with certain of the respective customer appliances, according to the priority assigned, to dynamically disconnect or adjust power-related operation of the certain of the respective customer appliances; and
transmitting confirmatory data over the first communication path or the second communication path to the central utility data center indicative of confirmation that the command was successfully carried out by the certain of the respective customer appliances.

9. The method of claim 8 , wherein receiving from the central utility data center over the first communication path and the customer home network or over the second communication path and the dedicated smart grid infrastructure communication network a command comprises receiving the command via the second communication path from a smart gateway integrated in the smart meter, the smart meter on site at a customer location.

10. The method of claim 9 , wherein receiving from the central power control authority over the first communication path and the customer home network or over the second communication path and the dedicated smart grid infrastructure communication network a command comprises receiving the command via the router and an Ethernet interface of a smart gateway, the router and the smart gateway on site with the respective customer appliances.

11. The method of claim 8 , wherein executing the command with certain of the respective customer appliances, according to the priority assigned, to dynamically disconnect or adjust power-related operation of the certain of the respective customer appliances further comprises activating or deactivating a relay or switch in electrical communication with the respective customer appliance to disconnect or adjust the power-related operation.

12. The method of claim 8 , wherein the respective customer appliances are plugged into one of a plurality of respective sockets of a smart plug in communication over the first communication path or the second communication path, and the method further comprises disconnecting certain of the respective customer appliances by the smart plug deenergizing a respective socket of a respective customer appliance based on the received command.

13. The method of claim 8 , wherein the priority is a tiered priority, and the respective customer appliances are plugged into one of a plurality of respective sockets of a smart plug in communication over the first communication path or the second communication path, and the method further comprises the smart plug receiving in the command, an instruction to curtail a first tier, and the smart plug deenergizing the respective sockets of only those respective customer appliances in the first tier while leaving other respective customer appliances in other tiers energized.

14. The method of claim 8 , wherein each of the respective customer appliances are plugged into one of a plurality of respective sockets of a smart plug in communication over the first communication path or the second communication path, and the method further comprises the smart plug gathering data from sensors in communication with at least some of the respective sockets, the smart plug transmitting the data via a network interface included in the smart plug over one of the first communication path or the
