Abstract

A computer-implemented method for an energy generation site includes detecting an energy storage device and its storage capacity, detecting an electrical grid operatively coupled to the energy generation site, and receiving event data corresponding to an event affecting the electrical grid. The method further includes determining a probability that the electrical grid will experience a power outage based on the event data, and charging the storage device according to a first charging profile or a second charging profile based on the probability. A maximum charge set point of the storage device for the first charging profile is less than the maximum storage capacity of the storage device, and the maximum charge set point for the second charging profile is at the maximum storage capacity of the storage device. The event data can be weather data, geological data, social media, or local alert data.

Claims (50)

1 . A computer-implemented method for an energy site, the method comprising:

detecting, by a processor, an energy storage device operatively coupled to the energy site;

determining, by the processor, an energy storage capacity of the energy storage device;

detecting, by the processor, an electrical grid operatively coupled to the energy site;

receiving, by the processor, event data corresponding to an event affecting the electrical grid;

determining, by the processor, a probability that the electrical grid will experience a power outage based on the event data;

charging the storage device according to a first charging profile when the probability is below a predetermined threshold value; and

charging the storage device according to a second charging profile when the probability is at or above the predetermined threshold value.

2 . The method of claim 1 wherein the event data is associated with at least one of local weather data, geological data, social media data, or local alert data.

3 . The method of claim 1 wherein the event data corresponds to the event occurring over a predetermined period of time.

4 . The method of claim 1 wherein the storage device is charged according to the first charging profile under normal operating conditions.

5 . The method of claim 1 further comprising:

receiving a user input corresponding to a manual selection of the second charging profile; and

charging the storage device according to the second charging profile.

6 . The method of claim 1 further comprising:

receiving a control signal from a control server, the control signal corresponding to an automated selection of the second charging profile; and

charging the storage device according to the second charging profile.

7 . A computer-implemented system comprising:

one or more processors;

one or more non-transitory computer-readable storage mediums containing instructions configured to cause the one or more processor to perform operations including:

determining an energy storage capacity of an energy storage device operatively coupled to a grid-connected energy generation site;

receiving weather data corresponding to a weather forecast over a predetermined period of time;

calculating a probability that the electrical grid will experience a power outage based on the weather data;

charging the storage device according to a first charging profile in response to the probability being below a predetermined threshold value; and

charging the storage device according to a second charging profile in response to the probability being at or above the predetermined threshold value.

8 . The system of claim 7 wherein a maximum charge set point of the storage device for the first charging profile is less than the maximum storage capacity of the storage device, and wherein the maximum charge set point of the storage device for the second charging profile is greater than the maximum charge set point of the first charging profile.

9 . The system of claim 7 further comprising instructions configured to cause the one or more processors to perform operations including limiting a time of using the second charging profile to extend the life of the storage device.

10 . The system of claim 7 wherein the storage device is charged according to the first charging profile under normal operating conditions.

11 . The system of claim 7 further comprising instructions configured to cause the one or more processors to perform operations including:

receiving a user input corresponding to a manual selection of the second charging profile; and

charging the storage device according to the second charging profile.

12 . The system of claim 7 further comprising instructions configured to cause the one or more processors to perform operations including:

receiving a control signal from a control server, the control signal corresponding to an automated selection of the second charging profile; and

charging the storage device according to the second charging profile.

13 . The system of claim 7 further comprising instructions configured to cause the one or more processors to perform operations including receiving event data corresponding to an event affecting an output of the electrical grid, wherein the calculated probability is further based on the event data.

14 . The system of claim 13 wherein the event data is associated with at least one of local geological data, social media data, or local alert data.

15 . The system of claim 7 further comprising:

a set of one or more photovoltaic cells used, at least in part, to charge the storage device according to the first charging profile or the second charging profile.

16 . A computer-implemented method comprising:

controlling, by a processor, a charging of an energy storage device according to a first charging profile under normal operating conditions, wherein the energy storage device is operatively coupled to an energy generation site, and wherein the energy generation site is operatively coupled to an electrical grid;

receiving, by the processor, event data corresponding to an event that could affect the electrical grid;

determining, by the processor, a probability that the electrical grid will experience a power outage based on the event data; and

charging the storage device according to a second charging profile when the probability is above a predetermined threshold value.

17 . The method of claim 16 wherein the energy storage device has a maximum storage capacity,

wherein a maximum charge set point of the energy storage device for the first charging profile is less than a storage capacity of the storage device, and

wherein the maximum charge set point of the storage device for the second charging profile is at the maximum storage capacity of the storage device.

18 . The method of claim 16 wherein the maximum charge set point for the first charging profile is 90% of the storage capacity of the storage device, and

wherein the maximum charge set point for the second charging profile is 100% of the storage capacity of the storage device.

19 . The method of claim 16 wherein the event data is associated with at least one of local weather data, local geological data, social media data, or local alert data.

20 . The method of claim 16 wherein the event data is associated with a local natural disaster including at least one of an earthquake, a fire, a tornado, hail, high winds, an avalanche, volcanic activity, a landslide, or an epidemic.
