  • Patent number: 10101731
    Abstract: Systems and methods for low level central plant optimization are provided. A controller for the central plant uses binary optimization to determine one or more feasible on/off configurations for equipment of the central plant that satisfy operating constraints and meet a thermal energy load setpoint. The controller determines optimum operating setpoints for each feasible on/off configuration and generates operating parameters including at least one of the feasible on/off configurations and the optimum operating setpoints. The operating parameters optimize an amount of energy consumed by the central plant equipment. The controller outputs the generated operating parameters via a communications interface for use in controlling the central plant equipment.

  • Patent number: 10074983
    Abstract: The technology is generally directed towards characterizing primary frequency response parameters (e.g., frequency response coefficient, inertia, damping, droop) for an interconnection, region, and power plant utilizing phasor measure unit (PMU) data captured during an event (e.g., a generation trip event) that causes an imbalance in the power grid system. Pre-processing of localized PMU based frequency measurements combined with system identification techniques fit the observed frequency response to estimate parameters such as system inertia, frequency response coefficient, turbine time constant, system damping and governor droop that characterize the interconnection-wide frequency response.

  • Patent number: 9974210
    Abstract: A central information management console provides for real time management of airflow across an information handling system or across multiple information handling systems within one or multiple racks within an environment by estimating and prioritizing the volumetric airflow needs of each information handling system within the environment. Each information handling system or group of information handling systems may be given a priority setting based on one or more criteria and volumetric airflow may be provided based on the priority setting and a selected balancing option. Metrics and sensor readings are received by the central information management console in real time or at intervals to use in determining the amount of volumetric airflow to provide to each information handling system so as to balance volumetric airflow for efficient operation of the environment and to maintain volumetric airflow so as not to exceed a volumetric airflow limit.

  • Patent number: 9964943
    Abstract: When a command for outputting a movement amount at a specific reference value is included in a command block, a numerical controller which controls a position of a control axis in synchronization with a reference value by using tabular data registers the reference value and the movement amount of the command in a shift table while associating the reference value with the movement amount. Then, when the current reference value reaches the reference value registered in the shift table, the numerical controller superposes the movement amount of the control axis that is associated with the reference value in the shift table on a distributed movement amount to the control axis, and outputs the superposed movement amount as a movement amount of the control axis.
