  • Publication number: 20180052478
    Abstract: The invention provides systems, methods, and devices relating to the provision of system-wide coordinated control voltage regulation support in power transmission and distribution networks using multiple inverter based power generation or absorption facilities, which are coupled to the power transmission and distribution networks for minimizing transmission and distribution line losses and for performing Conservation Voltage Reduction. The invention uses a novel control method of inverter based Distributed Generators as Static Synchronous Compensator (STATCOM) in a way that provides a dynamic voltage regulation/control with the inverter capacity remaining after real power generation or absorption, thereby decreasing system line losses and performing Conservation Voltage Reduction.

  • Publication number: 20180041460
    Abstract: A system and method for aggregating user response data in a communication system such as an instant messaging (IM system). Aggregation is performed according to a hierarchical group addressing structure into which users are arranged. Data may be input, output and distributed in a structured data format. Aggregating information comprises collating, in each group in the hierarchical group addressing structure, information contained in responses from individual users in that group. Aggregating said information may further comprise collating, for each group in the hierarchical group addressing structure, information contained in responses from all child groups subordinate to that group. Because the grouping structure for addressing or routing is pre-existing, no additional grouping or categorising of individuals or responses is required.

  • Publication number: 20180027068
    Abstract: In an instant messaging system users can be assigned groups to assist in distributing messages quickly and easily among designated users. A hierarchical grouping structure can be defined to provide increased control of groups and message routing. Parent and child groups can be defined, and a cascaded message flow can route messages from parent to child groups, but not from child to parent groups, which is particularly useful in very large systems with large numbers of users.

  • Patent number: 9767892
    Abstract: Integrated circuits with an array of memory cells are provided. Each memory cell may include at least one pair of cross-coupled inverters, write access transistors, and optionally a separate read port. The cross-coupled inverters in each memory cell may have a positive power supply terminal. The positive power supply terminal of each memory cell along a given column in the array may be coupled to a corresponding pull-up transistor. The pull-up transistor may receive a control signal from a pull-up weakening control circuit. The control signal may be temporarily elevated during write operations and may otherwise be driven back down to ground to help optimize read performance. The pull-up weakening control circuit may be implemented using a chain of n-channel transistors or a resistor chain.

  • Publication number: 20170250540
    Abstract: Systems, methods, and devices relating to operating a power generation facility to contribute to the stability of the power transmission system. A controller operates on the power generation facility to modulate real power or reactive power or both in a decoupled manner to contribute to the stability of the power transmission system. Real power produced by the power generation facility can be increased or decreased between zero and the maximum real power available from the PV solar panels, as required by the power system. Reactive power from the power generation facility can be exchanged (injected or absorbed) and both increased or decreased as required by the power transmission system. For solar farms, the solar panels can be connected or disconnected, or operated at non-optimal power production to add or subtract real or reactive power to the power transmission system.
