Cloud-Based Demand Response
Methods, systems, and apparatus for implementing cloud-based demand response are provided. Cloud-based demand response may be performed by publishing a demand response request at a communications node, the published demand response request including at least a load reduction request and an incentive price; initiating a load reduction bidding process in response to the published demand response request, the load reduction bidding process being accessible to customer nodes; and determining an updated incentive price based on at least one load reduction bid received from the customer nodes. The updated incentive price may be determined by a bisection function, and the at least one load reduction bid may be autonomously generated based on a customer cost function.
1 . A method comprising:
publishing an electric power demand response request at a communications node, the published demand response request including at least a load reduction request and an incentive price;
initiating a load reduction bidding process in response to the published demand response request, the load reduction bidding process being accessible to customer nodes; and
determining an updated incentive price based on at least one load reduction bid received from the customer nodes.
2 . The method of claim 1 , further comprising determining a time for stopping the load reduction bidding process based on the updated incentive price, wherein the updated incentive price at the time when the load reduction bidding process is stopped is the optimal incentive price.
3 . The method of claim 2 , further comprising transmitting the optimal incentive price to an electric utility provider.
4 . The method of claim 1 , further comprising publishing the updated incentive price.
5 . The method of claim 1 , further comprising determining whether the load reduction bidding process is feasible based on at least one load reduction bid.
6 . The method of claim 1 , wherein the updated incentive price is determined based on a bisection function.
7 . The method of claim 1 , further comprising selecting an arbitrary node for determining the updated incentive price, wherein the arbitrary node may be a customer node or a specialized computing node.
8 . The method of claim 7 , further comprising selecting the arbitrary node based on a hash function.
9 . The method of claim 1 , wherein the demand response request is based at least in part on electricity usage data collected from at least one customer node.
10 . The method of claim 1 , wherein the at least one load reduction bid is autonomously generated based on a customer cost function.
11 . The method of claim 1 , wherein the demand response request is determined by an electric utility provider and the customer nodes comprise an electric utility region.
12 . A communications node comprising:
a control hub adapted to:
publish an electric power demand response request, the published demand response request including at least a load reduction request and an incentive price;
initiate a load reduction bidding process in response to the published demand response request, the load reduction bidding process being accessible to customer nodes; and
determine an updated incentive price based on at least one load reduction bid received from the customer nodes.
13 . The communications node of claim 12 , wherein the control hub is further adapted to determine a time for stopping the load reduction bidding process based on the updated incentive price, wherein the updated incentive price at the time when the load reduction bidding process is stopped is the optimal incentive price.
14 . The communications node of claim 13 , wherein the control hub is further adapted to transmit the optimal incentive price to the electric utility provider.
15 . The communications node of claim 12 , wherein the control hub is further adapted to publish the updated incentive price.
16 . The communications node of claim 12 , wherein the control hub is further adapted to determine whether the load reduction bidding process is feasible based on at least one load reduction bid.
17 . The communications node of claim 12 , wherein the control hub is further adapted to determine the updated incentive price based on a bisection function.
18 . The communications node of claim 12 , wherein the control hub is further adapted to select an arbitrary node for determining the updated incentive price, wherein the arbitrary node may be a customer node or a specialized computing node.
19 . The communications node of claim 18 , wherein the control hub is further adapted to select the arbitrary node based on a hash function.
20 . An article of manufacture including a non-transitory computer-readable medium having instructions stored thereon, that in response to execution by a computing device causes the computing device to perform operations comprising:
publishing a demand response request from an electric utility provider at a node of a communications network, the published demand response request including at least a load reduction request and an incentive price;
initiating a load reduction bidding process in response to the published demand response request, the load reduction bidding process being accessible to customer nodes within a utility region; and
determining an updated incentive price based on at least one load reduction bid received from the customer nodes.
21 . A customer node, comprising:
a smart meter adapted to monitor electric power usage by a customer and determine a customer cost function based on the monitored electrical power usage; and
an energy management system unit in communication with the smart meter, the energy management system unit adapted to generate a load reduction bid based on the customer cost function in response to a published load reduction bid request.
22 . The customer node of claim 21 , wherein the energy management system unit is further adapted to determine whether to generate a load reduction bid in response to a published load reduction bid request.
23 . The customer node of claim 22 , wherein the energy management system unit is further adapted to determine whether to generate a load reduction bid for each iteration of a load reduction bidding process.
24 . A communications node, comprising:
an energy management system unit adapted to:
receive a signal indicating a selection to determine an updated incentive price for a load reduction bidding process;
receive load reduction bids generated based on a published demand response request for the load reduction bidding process; and
determine an updated incentive price based on the load reduction bids.
25 . The communications node of claim 24 , wherein the energy management system unit is further adapted to determine the updated incentive price based on a bisection function.
26 . The communications node of claim 24 , wherein the energy management system unit is further adapted to publish the updated incentive price.
