  • Patent number: 10324483
    Abstract: An energy storage system for a building includes a battery and an energy storage controller. The battery is configured to store electrical energy purchased from a utility and to discharge stored electrical energy for use in satisfying a building energy load. The energy storage controller is configured to generate a cost function including a peak load contribution (PLC) term. The PLC term represents a cost based on electrical energy purchased from the utility during coincidental peak hours in an optimization period. The controller is configured to modify the cost function by applying a peak hours mask to the PLC term. The peak hours mask identifies one or more hours in the optimization period as projected peak hours and causes the energy storage controller to disregard the electrical energy purchased from the utility during any hours not identified as projected peak hours when calculating a value for the PLC term.

  • Patent number: 9983610
    Abstract: A method includes separating a collection of devices configured for participation in a DR event into an On-to-Off DR device set (On-to-Off set) and an Off-to-On DR device set (Off-to-On set). The method includes portioning into transition groups devices of the On-to-Off set and/or devices of the Off-to-On set based at least partially on latency involved in command communication with one or more of the devices. The method includes scheduling state transitions of the transition groups such that an energy curtailment during the state transitions meets a curtailment margin of a total curtailment of the DR event. The method includes executing a micro DR event that includes the state transitions in which the devices in the transition groups are transitioned from a current state to an alternative state and the micro DR event curtails a portion of a total energy curtailment for the DR event.

  • Patent number: 9964980
    Abstract: An optimal power flow (OPF) problem formulates constraints and operation of an electric power system. A method and system is provided for generating a secure OPF solution that solves the OPF problem. A list of contingencies is created from system data. An OPF solution is computed for the electric power system to optimize an objective function value under the constraints of the electric power system. Voltage stability analysis is performed on the electric power system that operates in states represented by the OPF solution. Then the contingencies are ranked according to load margins of the electric power system. If there is at least an insecure contingency with a non-positive load margin in the list of contingencies, a set of preventive controls are computed and applied to control components in the electric power system. The method is performed iteratively to obtain the secure OPF solution.

  • Patent number: 9940666
    Abstract: A system and method of conducting a computer-based, simultaneous, multiple round, descending clock auction for basic generation services (BGS) includes receiving bids by an application server host application for processing bids according to auction rules, for tranche units of BGS products, calculating next round prices, and sending round results to bidders, the subsequent round prices and a notice of the number of tranches bid during the previous round and/or the amount of excess supply offered. Subsequently, an electronic withdrawal request to remove tranches from a product and reduce a maximum number bids the bidder can make in future rounds, and/or bidder exit price, is received, but may be partially or fully refused. When the number of tranches bid are equal to or less than a certain threshold for each of the products, the auction may end and bidders are awarded an ending price for each of the products won.

    Abstract: A method for controlling the ratio between injected and extracted electric energy in an electric energy supply grid with a number of grid participants, which are selected from a group including producers, consumers, and storage devices, with at least two of the group being included. A grid state variable is used as a control variable, the value of said variable depending on the ratio between inserted and extracted electric energy and being ascertainable from the grid by the grid participants. The invention is characterized in that a number of grid participants ascertain the grid state variable from the grid and use said variable at least indirectly to control the grid in a decentralized manner based on a respective specific grid participant behavior.
