  • Patent number: 11451061
    Abstract: Apparatus and methods are disclosed for restoring operation of a power grid comprising a plurality of reclosers and distributed energy resources (DERs) responsive to abnormal conditions by determining and implementing a reconfiguration for the power grid. The reconfiguration can specify respective new statuses for one or more of the reclosers and/or respective quantities of reactive power to be supplied by one or more of the DERs. The reconfiguration can be determined based on a plurality of constraints using an objective function, the constraints being determined based at least in part on recloser status data and/or DER power generation capability data. Respective cleared quantities of reactive power for the DERs to supply to the reconfigured power grid can be determined via a transactive control scheme, and the reconfiguration can be updated prior to implementation based on the results of the transactive control scheme.

  • Patent number: 11404875
    Abstract: Systems, methods and apparatuses are provided for reducing peak energy demand and to smooth intermittent energy profiles from onsite variable energy sources and loads. Some embodiments use system level and device level analysis and optimization to adaptively adjust the operation of a behind the meter energy storage (BMES) to smooth out energy generation variabilities and follow a reference load signal, including at short time resolutions.

  • Patent number: 11361392
    Abstract: 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.

  • Publication number: 20220179378
    Abstract: This document describes techniques, apparatuses, and systems for a blockchain-based transactive energy system. A blockchain-based transactive energy system receives a bid associated with a supply/demand curve of a utility from a transactive node through a smart contract. A universal identifier associated with the bid may be verified by consensus nodes of the blockchain-based transactive energy system to determine a verified set of bids. The universal identifier or other data associated with the bid may be stored in an immutable database provided by a blockchain. Based on the verified set of bids, a market-clearing price of the utility may be determined and used to satisfy the bid of the transactive node according to an actual production or consumption of the utility by the transactive node. The actual production or consumption of the utility may be stored in the immutable database for future audits or verification.

  • Publication number: 20220084139
    Abstract: Computing apparatus and methods to increase operational flexibility in an energy distribution system include using a transactive mechanism to adjust voltage supplied to a power grid by one or more distributed energy resources (DERs). In some examples of the disclosed technology, the transactive mechanism is configured to cause the one or more DERs to adjust a corresponding supply of voltage to the power grid in order to reach a targeted voltage difference across terminals of a switching device of the power grid, thereby enabling the switching device to be switched to increase reliability of the power grid.
