  • Patent number: 9589297
    Abstract: 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.

  • Publication number: 20160371796
    Abstract: Disclosed herein are exemplary embodiments of methods and systems that can be used to implement transactive control schemes for use in distributed transactive control power distribution systems. Embodiments of the disclosed technology include design methodologies that can be used to identify utility negotiation strategies that guarantee price-discovery in a finite time. Exemplary auctionless price discovery methods utilize a convergence acceleration factor that reduces the number of iterations between a supplier and a consumer transactive controller that are needed to reach agreement on an mutually acceptable price and quantity of electricity to transfer from the electricity supplier to the electricity consumer.
