Abstract

A network for managing distributed resources (DRs) is connected to an electric power system (EPS). The network includes a set of controllers, and multiple sets of the DRs, wherein each controller is connected to one of the sets of the DRs by a personal area network (PAN). A management system connects the EPS and the set of controllers by a wide area network (WAN). The EPS generates commands for selected DRs to take actions, the commands are routed to the selected DRs via the WAN and PANs.

Claims

1. A network for managing distributed resources (DRs) connected to an electric power system (EPS), comprising:

a set of controllers;

a plurality of sets of the DRs, wherein each controller is connected to one of the sets of the DRs by a personal area network (PAN);

a management system connected to the EPS and the set of controllers by a wide area network (WAN), wherein the EPS generates commands for selected DRs to take actions, the commands are routed to the selected DRs via the WAN and PANs.

2. The network of claim 1, further comprising:

a plurality of communication interfaces for interconnecting the sets of the DRs, the set of controllers, the management system, and the EPS.

3. The network of claim 1, wherein the WAN uses one-way or two-way communication interactions

4. The network of claim 1, wherein the controllers provide real-time direct control of the DRs.

5. The network of claim 1, further comprising:

an on-site management system connected to a subset of the controllers using a local area network (LAN).

6. The network of claim 1, wherein a particular controller is implemented in one of the DRs.

7. The network of claim 1, wherein a particular communication interface includes a wired and a wireless transceiver to receive duplicate copies of the command.

8. The network of claim 1, wherein the DRs generate a status report in response to the commands.

9. The network of claim 8, wherein the status report is need-based.

10. The network of claim 8, wherein the status report is request-based.

11. The network of claim 1, wherein the DRs include generator and storages.

12. The network of claim 4, wherein the real-time direct control is initiated by the EPS.

13. The network of claim 1, wherein the management system prevents islanding.
