Abstract

Techniques are described for incorporating distribution network analysis in the demand response scheduling process. In one example, a method includes receiving demand response (DR) request from a DR initiator, transmitting the DR request to an aggregator, for each customer, receiving customer location information and a customer DR value from the aggregator, aggregating DR at a distribution transformer in a distribution system, determining if there are any violations in the distribution system, determining an aggregated DR value for each electric node affected by the DR request, and transmitting each determined DR value to the DR initiator.

Claims

1. A method comprising:

receiving demand response (DR) request from a DR initiator;

transmitting the DR request to an aggregator;

for each customer, receiving customer location information and a customer DR value from the aggregator;

aggregating DR at a distribution transformer in a distribution system;

determining if there are any violations in the distribution system;

determining an aggregated DR value for each electric node affected by the DR request; and

transmitting each determined DR value to the DR initiator.

2. The method of claim 1, wherein the electric node is a substation.

3. The method of claim 1, wherein the electric node is a feeder.

4. The method of claim 1, further comprising:

determining a topological model of the distribution system.

5. The method of claim 4, wherein determining a topological model of the distribution system comprises:

receiving topological input data on the distribution system;

verifying the input data; and

determining a plurality of nodes on the distribution system and a plurality of branches on the distribution system, and determining connections between the plurality of nodes and the plurality of branches.

6. The method of claim 1, further comprising:

determining a status of at least one switch on the distribution system.

7. The method of claim 1 further comprising:

determining at least one violation on the distribution system based on the aggregated DR value associated with a respective electric node affected by the DR request.

8. The method of claim 7, wherein the at least one violation is related to cold load pickup.

9. The method of claim 7, wherein the at least one violation is related to asymmetric DR balancing between phases.

10. A computer-readable storage medium comprising instructions that, when executed by a processor, cause the processor to:

receive demand response (DR) request from a DR initiator;

transmit the DR request to an aggregator;

for each customer, receive customer location information and a customer DR value from the aggregator;

aggregate DR at a distribution transformer in a distribution system;

determine if there are any violations in the distribution system;

determine an aggregated DR value for each electric node affected by the DR request; and

transmit each determined DR value to the DR initiator.

11. The computer-readable storage medium of claim 10, wherein the electric node is a substation.

12. The computer-readable storage medium of claim 10, wherein the electric node is a feeder.

13. The computer-readable storage medium of claim 10, further comprising instructions that, when executed by a processor, cause the processor to:

determine a topological model of the distribution system.

14. The computer-readable storage medium of claim 13, wherein the instructions that cause the processor to determine a topological model of the distribution system further comprise instructions that, when executed by a processor, cause the processor to:

receive topological input data on the distribution system;

verify the input data; and

determine a plurality of nodes on the distribution system and a plurality of branches on the distribution system, and determining connections between the plurality of nodes and the plurality of branches.

15. The computer-readable storage medium of claim 10, further comprising instructions that, when executed by a processor, cause the processor to:

determine a status of at least one switch on the distribution system.

determine at least one violation on the distribution system based on the aggregated DR value associated with a respective electric node affected by the DR request.

17. The computer-readable storage medium of claim 16, wherein the at least one violation is related to cold load pickup.

18. The computer-readable storage medium of claim 16, wherein the at least one violation is related to asymmetric DR balancing between phases.

19. A system comprising:

means for receiving demand response (DR) request from a DR initiator;

means for transmitting the DR request to an aggregator;

for each customer, means for receiving customer location information and a customer DR value from the aggregator;

means for aggregating DR at a distribution transformer in a distribution system;
