Abstract
Methods, systems, and apparatus, including computer programs encoded on a storage device, for determining whether a distributed energy resource is connected at a location. Electrical load data is obtained for a location over a time period. The electrical load data is analyzed to determine one or more signals from the electrical load data. The signals are compared to one or more load profiles for the location. Each load profile can indicate one or more baseline electrical patterns for the location. A likelihood that at least one distributed energy resource is in use at the location is determined based on the comparison. In response to determining that the likelihood is more than a threshold, one or more actions are performed.
Claims23
A computer-implemented method for determining whether a distributed energy resource is connected at a location, comprising:
- obtaining electrical load data for a portion of an electric power grid over a time period, wherein the portion of the electric power grid comprises at least one substation and at least one electrical feeder;
- analyzing the electrical load data to determine at least one signal from the electrical load data;
- comparing the at least one signal to at least one load profile for the location, wherein each load profile indicates one or more baseline electrical patterns for the location;
- determining a likelihood that at least one distributed energy resource is in use at the location based on the comparison;
- and
- in response to determining that the likelihood is more than a threshold:
- generating distributed energy resource capacity information for the at least one distributed energy resource based on the comparison;
- and
- balancing one or more feeders based on the distributed energy resource capacity information.
A system comprising one or more computers and one or more storage devices on which are stored instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations for determining whether a distributed energy resource is connected at a location comprising:
- obtaining electrical load data for a portion of an electric power grid over a time period, wherein the portion of the electric power grid comprises at least one substation and at least one electrical feeder;
- analyzing the electrical load data to determine at least one signal from the electrical load data;
- comparing the at least one signal to at least one load profile for the location, wherein each load profile indicates one or more baseline electrical patterns for the location;
- determining a likelihood that at least one distributed energy resource is in use at the location based on the comparison;
- and
- in response to determining that the likelihood is more than a threshold:
- generating distributed energy resource capacity information for the at least one distributed energy resource based on the comparison;
- and
- balancing one or more feeders based on the distributed energy resource capacity information.
A non-transitory computer storage medium encoded with instructions that, when executed by one or more computers, cause the one or more computers to perform operations for determining whether a distributed energy resource is connected at a location comprising:
- obtaining electrical load data for a portion of an electric power grid over a time period, wherein the portion of the electric power grid comprises at least one substation and at least one electrical feeder;
- analyzing the electrical load data to determine at least one signal from the electrical load data;
- comparing the at least one signal to at least one load profile for the location, wherein each load profile indicates one or more baseline electrical patterns for the location;
- determining a likelihood that at least one distributed energy resource is in use at the location based on the comparison;
- and
- in response to determining that the likelihood is more than a threshold:
- generating distributed energy resource capacity information for the at least one distributed energy resource based on the comparison;
- and
- balancing one or more feeders based on the distributed energy resource capacity information.
