Abstract

A distributed ledger based utility system architecture may be configured to enable secure payments, data transmission, and meter configuration of smart sensors. The utility system architecture may be a tiered architecture including multiple nodes at different levels of the architecture where each level may contain a different portion of the distributed ledger. As information is added to the distributed ledger, each portion of the distributed ledger may be updated based on whether the information is relevant to that node. The information may include rate contract transactions, meter configuration data transactions, payment transactions, or the like.

First claim

The invention claimed is:

1. A utility network system comprising:
a master node including a master node distributed ledger, the master node configured to receive a customer transaction and to update an instance of the master node distributed ledger indicating occurrence of the customer transaction;
a plurality of broker nodes configured to receive an activity instruction including a demand response instruction and meter configuration data for a plurality of smart utility meters located within an autonomous routing area, each broker node comprising an edge node of the autonomous routing area and including a broker node distributed ledger that is applicable to the respective broker node; and
the plurality of smart utility meters located within the autonomous routing area configured to:
receive the activity instruction including the demand response instruction and the meter configuration data,
wherein the demand response instruction includes an indication of which loads of a plurality of loads are needed to be altered in order to fulfill an amount of a resource indicated in the demand response instruction;
alter an amount of resource provided to at least one load of the plurality of loads; and
set a signal strength used by at least one smart utility meter of the plurality of smart utility meters based at least in part on the meter configuration data.

2. The utility network system of claim 1 , wherein the plurality of loads include at least one of an appliance, an electric vehicle charging station, a lighting system, an HVAC system, or a sprinkler system.

3. The utility network system of claim 1 , wherein the at least one smart utility meter alters the amount of resource provided to at least one load of the plurality of loads in response to a user turning off the at least one load.

4. The utility network system of claim 1 , further comprising a user device configured to receive a demand response offer from a supplier of the resource and wherein the customer transaction includes an indication that the supplier of the resource received a pledge from the user device to participate in a demand response event and the supplier of the resource is configured to register the at least one smart utility meter to participate in the demand response event in response to receiving the pledge from the user device to participate in the demand response event.

5. The utility network system of claim 4 , wherein the master node is further configured to:
determine that a predetermined threshold of an amount of utility has been met;
determine that the pledge received from the user device has been fulfilled; and
transfer funds to update a balance associated with the at least one smart utility meter.

6. The utility network system of claim 4 , wherein the demand response offer includes an indication of a credit to be provided to a smart utility meter associated with a user of the user device in response to the user agreeing to participate in the demand response event and the utility network system is further configured to provide the credit to the smart utility meter and updating the instance of the broker node distributed ledger indicating occurrence of providing the credit.

7. The utility network system of claim 1 , wherein the master node is further configured to:
determine that a predetermined threshold of an amount of utility has not been met; and
send a transmission to at least one broker node of the plurality of broker nodes causing the at least one broker node to determine additional loads of the plurality of loads needed to be altered such that the amount of utility meets the predetermined threshold.

8. A method implemented by a utility network system, the method comprising:
receiving, at a master node of the utility network system, a customer transaction and updating an instance of a master node distributed ledger indicating occurrence of the customer transaction;
receiving, at a broker node of a plurality of broker nodes of the utility network system, an activity instruction including a demand response instruction and meter configuration data for a plurality of smart utility meters located within an autonomous routing area, each broker node comprising an edge node of the autonomous routing area and including a broker node distributed ledger that is applicable to the respective broker node;
receiving, by the plurality of smart utility meters, the activity instruction including the demand response instruction and the meter configuration data, wherein the demand response instruction includes an indication of which loads of a plurality of loads are needed to be altered in order to fulfill an amount of a resource indicated in the demand response instruction;
altering, by the plurality of smart utility meters, an amount of resource provided to at least one load of the plurality of loads; and
changing metrology channels collected by at least one smart utility meter of the plurality of smart utility meters based at least in part on the meter configuration data.

9. The method of claim 8 , wherein the plurality of loads include at least one of an appliance, an electric vehicle charging station, a lighting system, an HVAC system, or a sprinkler system.

10. The method of claim 8 , wherein a respective smart utility meter alters the amount of resource provided to at least one load of the plurality of loads in response to a user turning off the at least one load.

11. The method of claim 8 , further comprising receiving, at a user device, a demand response offer from a supplier of the resource and wherein the customer transaction includes an indication that the supplier of the resource received a pledge from the user device to participate in a demand response event and the supplier of the resource is configured to register the at least one smart utility meter to participate in the demand response event in response to receiving the pledge from the user device to participate in the demand response event.

12. The method of claim 11 , wherein the master node is further configured to:
determine that a predetermined threshold of an amount of utility has been met;
determine that the pledge received from the user device has been fulfilled; and
transfer funds to update a balance associated with the at least one smart utility meter.

13. The method of claim 11 , wherein the demand response offer includes an indication of a credit to be provided to a smart utility meter associated with a user of the user device in response to the user agreeing to participate in the demand response event and the method further comprises providing the credit to the smart utility meter and updating the instance of the broker node distributed ledger indicating occurrence of providing the credit.

14. The method of claim 8 , wherein the master node is further configured to:
determine that a predetermined threshold of an amount of utility has not been met; and
send a transmission to at least one broker node of the plurality of broker nodes causing the at least one broker node to determine additional loads of the plurality of loads needed to be altered such that the amount of utility meets the predetermined threshold.

15. The method of claim 8 , wherein the at least one smart utility meter of the plurality of smart utility meters is further configured to receive a transmission indicating an update to a distributed ledger associated with the at least one smart utility meter, the update including an activity instruction to update a balance associated with the at least one smart utility meter.

16. The method of claim 8 , wherein the master node comp
