Abstract

Methods, systems, and computer program products for load profile selection in islanding using batteries are provided herein. A computer-implemented method includes generating a usage pattern model for a battery based on (i) information pertaining to consumers of the battery, (ii) information pertaining to usage of the battery, and (iii) information pertaining to network outages, wherein the network is linked to the battery; selecting a subset of the consumers of the battery to supply energy from the battery, during a network outage, based on (i) the usage pattern model, (ii) the lifespan of the battery, (iii) performance of the network, (iv) historical consumption data attributed to each of the consumers, and (v) a predetermined minimum amount of energy required to be supplied to the consumers during a network outage; and outputting instructions to activate and/or deactivate distribution components within the network based on said selecting.

First claim

selecting a subset of the multiple consumers of the battery, to supply energy from the battery during a network outage, based on (i) the generated usage pattern model for the battery, (ii) a metric pertaining to the lifespan of the battery, (iii) a metric pertaining to performance of the network, (iv) historical consumption data attributed to each of the multiple consumers, and (v) a predetermined minimum amount of energy required to be supplied to the multiple consumers during a network outage; and
outputting instructions, based on the selected subset of consumers, to at least one of (i) activate multiple distribution components within the network and (ii) deactivate multiple distribution components within the network;
wherein the steps are carried out by at least one computing device.

2. The computer-implemented method of claim 1 , wherein the one or more items of information pertaining to multiple consumers of the battery comprises identification of a location of each of the multiple consumers.

3. The computer-implemented method of claim 1 , wherein said generating the usage pattern model for a battery is further based on one or more bounds for energy usage for each of the multiple consumers derived from historical usage data attributed to each of the multiple consumers.

4. The computer-implemented method of claim 1 , wherein the one or more items of information pertaining to usage of the battery comprises historical usage data of the battery.

5. The computer-implemented method of claim 1 , wherein the one or more items of information pertaining to usage of the battery comprises manufacturer data pertaining to one or more characteristics of the battery.

6. The computer-implemented method of claim 1 , wherein the one or more items of information pertaining to one or more network outages comprises a duration measure for each of the one or more network outages.

7. The computer-implemented method of claim 1 , wherein the one or more items of information pertaining to one or more network outages comprises a frequency measure for each of the one or more network outages.

8. The computer-implemented method of claim 1 , wherein the metric pertaining to performance of the network comprises a system average interruption frequency index.

9. The computer-implemented method of claim 1 , wherein the metric pertaining to performance of the network comprises a system average interruption duration index.

10. The computer-implemented method of claim 1 , wherein the metric pertaining to the lifespan of the battery comprises a number of charging and discharging cycles of the battery.

11. The computer-implemented method of claim 1 , comprising:
outputting one or more discharge profiles pertaining to the battery.

12. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to:
