Business Methods in a Power Aggregation System for Distributed Electric Resources
Systems and methods are described for a power aggregation system. In one implementation, a method includes determining a level of renewable energy on a power grid, determining a price of electricity on the power grid, and scheduling a charging of an electric resource connected to the power grid as a function of the price of electricity on the power grid and the level of renewable energy on the power grid.
1 . A method, comprising:
determining a level of renewable energy on a power grid; and
scheduling a charging of an electric resource connected to the power grid to occur when the level of renewable energy on the power grid is greater than a predicted value.
2 . The method of claim 1 , wherein the renewable energy on the power grid comprises wind energy.
3 . The method of claim 1 , wherein the renewable energy on the power grid comprises solar energy.
4 . The method of claim 1 , wherein the renewable energy on the power grid comprises hydroelectric energy.
5 . The method of claim 1 , wherein the renewable energy on the power grid comprises geothermal energy.
6 . The method of claim 1 , wherein the renewable energy on the power grid comprises biomass energy.
7 . The method of claim 1 , wherein the predicted value is a function of user preferences of the electric resource.
8 . The method of claim 1 , wherein the electric resource comprises an electric vehicle, a hybrid electric vehicle, or a vehicle that obtains at least some power for motion from an electric storage system.
9 . The method of claim 1 , wherein the electric resource is connected to a power aggregation system.
10 . A method, comprising:
determining a price of electricity on a power grid; and
scheduling a charging of an electric resource connected to the power grid to occur when the price of electricity on the power grid is less than a predicted value.
11 . The method of claim 10 , wherein determining the price of electricity on the power grid comprises determining a rate structure of the power grid.
12 . The method of claim 11 , wherein the rate structure of the power grid is a function of time of use (TOU), critical peak pricing (CPP), and real time pricing (RTP).
13 . The method of claim 10 , wherein the predicted value is a function of user preferences of the electric resource.
14 . The method of claim 10 , wherein the predicted value is a function of electric resource type and/or state-of-charge.
15 . The method of claim 10 , wherein the electric resource comprises an electric vehicle, a hybrid electric vehicle, or a vehicle that obtains at least some power for motion from an electric storage system.
16 . The method of claim 10 , wherein the electric resource is connected to a power aggregation system.
17 . A method, comprising:
charging an electric resource connected to a power grid;
metering an amount of energy transferred from the power grid to the electric resource; and
purchasing proof that a portion of the amount of energy transferred was generated from a renewable energy source.
18 . The method of claim 17 , wherein the proof comprises a renewable energy certificate (REC).
19 . The method of claim 17 , wherein the electric resource comprises an electric vehicle, a hybrid electric vehicle, or a vehicle that obtains at least some power for motion from an electric storage system.
20 . The method of claim 17 , wherein the electric resource is connected to a power aggregation system.
21 . A method, comprising:
determining a price of electricity on a power grid;
determining a level of renewable energy on a power grid; and
scheduling a charging of an electric resource connected to the power grid as a function of the price of electricity on the power grid and the level of renewable energy on the power grid.
22 . The method of claim 21 , further comprising:
determining a status of the electric resource; and
scheduling a charging of the electric resource as a function of the status of the electric resource.
23 . The method of claim 22 , wherein the status comprises a state of charge of the electric resource.
24 . The method of claim 21 , further comprising:
determining a user preference of the electric resource; and
scheduling a charging of the electric resource as a function of the user preference of the electric resource.
25 . The method of claim 24 , wherein the user preference comprises frequency of use.
26 . The method of claim 24 , wherein the user preference comprises a user override.
27 . The method of claim 21 , wherein the electric resource comprises an electric vehicle, a hybrid electric vehicle, or a vehicle that obtains at least some power for motion from an electric storage system.
28 . The method of claim 21 , wherein the electric resource is connected to a power aggregation system.
