Abstract

Systems that allow energy allocation for energy storage cooperation are disclosed, with specific methods outlined concerning allocating energy stored by an energy storage device between a utility provider, a customer, and/or a third party. The methods may include allocating a portion of stored energy for a utility provider'"'"'s benefit which may be gained as a result of a part of the allocated energy being dispatched into a utility network and allocating another portion of energy stored in the energy storage device for the benefit of the customer. Additional embodiments disclose the dispatching of the energy stored, signals used to bring about a dispatch, the nature of the relationship between the utility provider, the customer, and the energy stored, methods for making energy available to a utility provider without a prearranged reservation of the energy, penalties for misallocating energy, apparatus for allocating energy and causing dispatch, and more.

Claims

1. A method of allocating energy storage between a utility provider and a customer, the method comprising:

providing a power management system at a site of a customer of a utility provider, the power management system including a system controller and an energy storage device connected to a utility network of the utility provider, the system controller being configured to manage the charge and discharge actions of the energy storage device;

allocating a first portion of energy stored in the energy storage device for use by the utility provider upon discharge of the first portion of energy into the utility network and allocating a second portion of energy stored in the energy storage device for use by the customer, wherein the first and second portions of energy are allocated by at least one of physically partitioning, electrically partitioning, or virtually partitioning the first and second portions of energy from each other;

providing direct control to the utility provider over the dispatch of the first portion of energy into the utility network by granting control over the system controller to the utility provider;

providing an incentive to the customer to reserve the first portion of energy stored in the energy storage device for use by the utility provider without transferring the first portion of energy to the utility provider;

compensating a party other than the customer as a result of the party other than the customer allocating the second portion of energy for the use of the customer independent of the utility provider.

2. The method of claim 1, further comprising storing the first portion of allocated energy and the second portion of allocated energy in the energy storage device.

3. The method of claim 1, further comprising yielding part of the first portion of allocated energy to the utility network.

4. The method of claim 3, wherein the yielding of allocated energy is performed at the discretion of the utility provider.

5. The method of claim 1, further comprising receiving part of the first portion of allocated energy into the utility network.

6. The method of claim 1, further comprising preventing the customer from consuming a portion of allocated energy.

7. The method of claim 1, further comprising compensating the customer for allocating the first portion of energy stored in the energy storage device for the use of the utility provider.

8. The method of claim 1, further comprising connecting the energy storage device to the utility network.

9. The method of claim 1, wherein the first portion of allocated energy is stored in a division of the energy storage device and is cycled between said division and one or more other divisions of the energy storage device.

10. The method of claim 1, wherein the first portion of allocated energy is allocated from an energy storage device operated by the customer.

11. The method of claim 1, wherein the second portion of allocated energy is allocated from an energy storage device operated by a party other than the customer.

12. The method of claim 1, wherein the benefit to the utility provider includes demand reduction in the utility network.

13. The method of claim 1, wherein the energy storage device is part of one of (a) a backup power source, (b) a power management system, (c) a load leveling device, and (d) a peak mitigation device.

14. The method of claim 1, wherein the utility provider is represented by an agent, employee, or other representative acting under the direction of a utility production or distribution administrator.

15. A method comprising:

receiving part of a first allotment of energy that has been discharged into a utility network from an energy repository, the first allotment of energy having been reserved for use by a utility network administrator, the first allotment of energy having been stored in the energy repository with a second allotment of energy that has been reserved for use by a customer, the first and second allotments of energy having been at least one of physically partitioned, electrically partitioned, or virtually partitioned from each other at the energy repository;

compensating a party other than the customer as a result of the party other than the customer allocating the second portion of energy for the use of the customer, wherein the party other than the customer allocates the second portion of energy for the use of the customer independent of the utility provider;

wherein the first allotment of energy is discharged into the utility network under direct control of the utility network administrator.

16. The method of claim 15, wherein the discharged reserved energy supplements another energy source in the utility network.
