Abstract

A method and system for controlling distributed energy resources is provided. Notification of an upcoming regional power distribution event is received and a distributed energy resource affected by the upcoming event is determined or identified. A first notification message is sent to an affected distributed energy resource asset owner or other administrator to notify the distributed energy resource asset of the event. An event data process is initiated to monitor and collect data associated with the event and an event control process is initiated to control one or more affected distributed energy resource asset during the event. The event control process and the event data process are terminated at the end of the event.

Claims

1. A method for controlling distributed energy resources, the method comprising:

receiving notification of an upcoming regional power distribution event;

determining a distributed energy resource affected by the upcoming event;

determining an optimal control threshold for controlling an affected distributed energy resource asset using facility conditions and/or electric grid conditions;

sending a first notification message to an affected distributed energy resource asset administrator to notify the distributed energy resource asset administrator of the event;

in response to the first notification message, initiating an event data process to monitor and collect data associated with the event and initiating an event control process utilizing the optimal control threshold to control the affected distributed energy resource asset during the event;

terminating the event control process at the end of the event; and

terminating the event data process.

2. A method according to claim 1, wherein the receiving notification of an upcoming regional power distribution event includes receiving a request to reduce demand of electricity from the electric power distribution grid.

3. A method according to claim 2, wherein the receiving a request to reduce demand of electricity from the electric power distribution grid includes receiving a request to reduce demand of electricity from the electric power distribution grid according to a predefined program.

4. A method according to claim 3, wherein the predefined program identifies one or more distributed energy resource assets available to respond to the event.

5. A method according to claim 1, further comprising sending a second notification message to the distributed energy resource asset administrator, the second notification message identifying distributed energy resource assets affected by the event.

6. A method according to claim 5, wherein the second notification message provides means by which the distributed energy resource asset may opt to be excluded or included in the event.

7. A method according to claim 5, wherein the second notification message is sent based on the site configuration of the distributed energy resource asset.

8. A method according to claim 1, wherein sending a first notification message to an affected distributed energy resource asset administrator to notify the distributed energy resource asset administrator of the event initiates a first event timer which stops timing when the event starts.

9. A method according to claim 8, wherein a second event timer is initiated when the first event timer stops timing, and the second event timer stops timing upon receipt of an event termination signal.

10. A method according to claim 1, further comprising verifying data transfers associated with the regional power distribution event.

11. A method according to claim 1, further comprising confirming states associated with affected distributed energy resource assets.
