Patent number: 11361392Abstract: Methods and apparatus provide flexible allocation and regulation of scheduled energy transfers between energy storage devices (“batteries”) and a power grid. Piecewise mappings having at least one sloping segment enable gradual variations in scheduled energy transfers as cleared values of a medium of energy exchange deviate from predicted values of the medium of energy exchange. Thereby deviations from a battery's predicted energy transfer schedule can be reduced, and overall smoother operation of a power grid can be achieved. Two sloping linear segments can be separated by a dead band, a portion of the mapping in which the scheduled energy transfer amount is invariant. A dead zone can increase the likelihood of a battery meeting its predicted schedule.Type: GrantFiled: November 1, 2019Date of Patent: June 14, 2022Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Bishnu P. Bhattarai, Bilal Ahmad Bhatti, Robert G. Pratt, Donald J. Hammerstrom, Steven E. Widergren

Patent number: 9589297Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems for distributing a resource (such as electricity) using a resource allocation system. One of the disclosed embodiments is a method for operating a transactive thermostatic controller configured to submit bids to a market-based resource allocation system. According to the exemplary method, a first bid curve is determined, the first bid curve indicating a first set of bid prices for corresponding temperatures and being associated with a cooling mode of operation for a heating and cooling system. A second bid curve is also determined, the second bid curve indicating a second set of bid prices for corresponding temperatures and being associated with a heating mode of operation for a heating and cooling system. In this embodiment, the first bid curve, the second bid curve, or both the first bid curve and the second bid curve are modified to prevent overlap of any portion of the first bid curve and the second bid curve.Type: GrantFiled: April 28, 2011Date of Patent: March 7, 2017Assignee: Battelle Memorial InstituteInventors: Jason C.

Nested, hierarchical resource allocation schema for management and control of an electric power grid
Patent number: 9425620Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems for distributing a resource (such as electricity) using a resource allocation system. In one exemplary embodiment, a system is disclosed comprising a first feeder network configured to deliver electrical power to a first plurality of customers. The first feeder network is controlled by a first market-based pricing system that computes a first feeder network price of electrical power at first periodic intervals. The system of this embodiment further comprises a second feeder network configured to deliver electrical power to a second plurality of customers. The second feeder network is controlled by a second market-based pricing system that computes a second feeder network price of electrical power at second periodic intervals.Type: GrantFiled: January 12, 2010Date of Patent: August 23, 2016Assignee: Battelle Memorial InstituteInventors: David P.

Patent number: 9342850Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems for distributing a resource (such as electricity) using a resource allocation system. One of the disclosed embodiments is a method for generating a bid value for purchasing electricity in a market-based resource allocation system. In this embodiment, a desired performance value indicative of a user's desired performance level for an electrical device is received. Price information from an electricity futures market is received. A bid value for purchasing electricity from a local resource allocation market sufficient to operate the electrical device at the desired performance level is computed. In this embodiment, the computing is performed based at least in part on the desired performance value and based at least in part on the price information from the electricity futures market.Type: GrantFiled: March 18, 2013Date of Patent: May 17, 2016Assignee: Battelle Memorial InstituteInventors: David P.
