    Abstract: Architectures, apparatuses, methods, systems, and techniques for controlling electrical power distribution network are disclosed. Embodiment distributed, hierarchical controls including layered locational energy service control variables may be utilized to determine and control the provision of energy services, including real power, reactive power (VAR), and capacity reserves, by DERs in a distribution network. In a first ex-ante iteration a simulation may be performed to calculate a set of subnetwork-specific control variables based on subnetwork locational energy service prices and a plurality of sets of DER-specific control variables based on DER locational energy service prices. A second ex-ante iteration calculates a set of actual subnetwork-specific control variables based on subnetwork locational energy service prices and a plurality of sets of actual DER specific control variables based on DER locational energy service prices.

  • Patent number: 11850555
    Abstract: A dual-layer membrane and a method for preparing thereof. By adding a modifying monomer containing an active group and a characteristic group to a dope solution or spinning solution during the preparation of the dual-layer membrane, the grafting reaction occurs between the active group of the monomer and the polymer in the dope solution or spinning solution, and the intermolecular interaction with other polymers is enhanced by the characteristic group of the monomer, to improve the miscibility between the polymers. The method is suitable for preparing both a dual-layer flat sheet membrane and a dual-layer hollow fiber membrane, and can realize the preparation of a dual-layer membrane with an interpenetrated structure at the interface under mild preparation conditions.

  • Patent number: 11728640
    Abstract: Systems and methods for fault detection and protection in electric power systems that evaluates electromagnetic transients caused by faults. A fault can be detected using sampled data from a first monitored point in the power system. Detection of fault transients and associated characteristics, including transient direction, can also be extracted through evaluation of sample data from other monitored points in the power system. A monitoring device can evaluate whether to trip a switching device in response to the detection of the fault and based on confirmation of an indication of detection of fault transients at the other monitored points of the power system. The determination of whether to trip or activate the switching device can also be based on other factors, including the timing of receipt of an indication of the detection of the fault transients and/or an evaluation of the characteristics of the detected transients.

  • Patent number: 10365676
    Abstract: Methods and systems for secured control of circuit breakers in an electric power substation against undesired direct operation. Consequences of a malicious action are prevented or mitigated using a validation approach that either blocks the command or ensures a negligible effect on system operation. An example method, suitable for implementation in a monitoring device in an electric power substation, includes receiving a command to open or close a circuit breaker. In response, one or more state parameters for the electric power network that comprises the substation are then predicted, the predicted state parameters reflecting an operating state for the network under the assumption that the received command is executed. The method further comprises comparing the predicted one or more state parameters to corresponding operational limits. Execution of the command is then blocked, in response to determining that one or more of the predicted state parameters violate the corresponding operational limits.
