Abstract

A system and method for detecting anomalies in the measurement and distribution of utilities is disclosed. Utility metering data obtained at a utility meter is received through a communications network. A utility consumption associated with an entity is then measured based on the utility metering data. The utility consumption can then be monitored for anomalies based on entity profile characteristics associated with the entity. The utility analytics system and method can be applied to the electrical utility industry, but also applicable to gas and water distribution, and other utilities.

receiving, through a communications network, utility metering data obtained at a utility meter of a plurality of network elements characterizing a network topology, the plurality of network elements comprising a plurality of meters including the utility meter, a plurality of transformers, a plurality of circuits, and at least one substation;

measuring, based on the utility metering data, a utility consumption associated with an entity, the entity being a physical property; and

monitoring the utility consumption for an anomaly based on entity profile characteristics associated with the entity, the monitoring comprising computing real-time values of utility consumption characteristics of at least one peer grouping including a plurality of entities with similar entity profile characteristics, the plurality of entities including the entity, the at least one peer grouping comprising one or more peers of the entity, the at least one peer grouping being refined when new data associated with the utility consumption is received, the monitoring comprising comparing the real-time values of the at least one peer grouping with the utility consumption associated with the entity to determine the anomaly, the at least one peer grouping being refined by executing a plurality of weighting algorithms on updated peer profile data associated with the entity, the utility consumption characteristics comprising a ratio of current load on a transformer of the plurality of transformers to an average load on the transformer during a predetermined period of time, the monitoring comprising determining changes in the network topology, the monitoring being further based on patterns of utility consumption of the entity, the patterns being updated in real-time.

2. A method in accordance with claim 1, wherein:

the monitoring further comprises comparing the utility consumption associated with the entity to one or more peer profiles associated with the entity; and

the monitoring is based on at least one of a construction date and renovation date associated with the entity.

3. A method in accordance with claim 2, further comprising generating one or more peer groupings based on the one or more peer profiles associated with the entity.

4. A method in accordance with claim 3, further comprising linking the utility consumption associated with the entity to at least one of the one or more peer groupings.

5. A method in accordance with claim 3, further comprising:

receiving the updated peer profile data associated with the entity before the refining using the plurality of weighting algorithms.

6. A method in accordance with claim 2, further comprising normalizing the utility consumption associated with an entity based on the entity profile characteristics and peer profiles associated with the entity.

7. A method in accordance with claim 1, wherein the entity profile characteristics associated with the entity comprise:

a postal code of the physical property, a square footage size of the physical property, a number of bedrooms in the physical property, whether the physical property includes a pool, and standard industry codes associated with the physical property.

8. A method in accordance with claim 1, wherein the utility consumption associated with an entity characterizes an amount of gas and water used at the physical property.

9. A method in accordance with claim 1, wherein the monitoring further comprises determining fluctuations based on weather patterns, daylight savings, and affluence of a particular neighbourhood of the physical property.

10. A utility analytics system comprising:

an analytics computer adapted to receive utility metering data obtained at a utility meter of a plurality of network elements characterizing a network topology, the plurality of network elements comprising at least a transformer, the analytics computer adapted to measure a utility consumption associated with an entity based on the utility metering data, and to monitor the utility consumption for one or more anomalies based on entity profile characteristics associated with the entity, the monitoring comprising computing real-time values of utility consumption characteristics of at least one peer grouping that includes a plurality of entities having similar profile characteristics, and comparing the real-time values of the at least one peer grouping with the utility consumption associated with the entity, the at least one peer grouping being refined by executing a plurality of weighting algorithms on updated peer profile data associated with the entity, the utility consumption characteristics comprising a ratio of a monthly load on the transformer of the plurality of transformers to an average load on the transformer, the monitoring accounting for changes in the network topology, the at least one peer grouping being modified when new data associated with the utility consumption is received in real-time, the monitoring being further based on data presented by one or more peers of the entity, the data presented by the one or more peers indicating a change in the entity profile characteristics associated with the entity, the monitoring being further based on patterns of utility consumption of the entity, the patterns being updated in real-time.

11. A system in accordance with claim 10, wherein the analytics computer is further adapted to compare the utility consumption associated with the entity to one or more peer profiles associated with the entity.

12. A system in accordance with claim 11, wherein the analytics computer is further adapted to generate one or more peer groupings based on the one or more peer profiles associated with the entity.
