  • Patent number: 11385605
    Abstract: A controller for operating building equipment of a building including processors and non-transitory computer-readable media storing instructions that, when executed by the processors, cause the processors to perform operations including obtaining a first setpoint trajectory from a cloud computation system. The first setpoint trajectory includes setpoints for the building equipment or for a space of the building. The setpoints correspond to time steps of an optimization period. The operations include determining whether a connection between the controller and the cloud computation system is active or inactive at a time step of the optimization period and determining an active setpoint for the time step of the optimization period using either the first or second setpoint trajectory based on whether the connection between the controller and the cloud computation system is active or inactive at the time step. The operations include operating the building equipment based on the active setpoint.

  • Patent number: 11336199
    Abstract: An improved AC power supply is described. The supply identifies the load through monitoring the current and voltage wave forms and phase relations with the AC Mains. The comparison is done in conditions where the power to the load is programmably varied through use of a control switch located in the line and neutral between the AC mains and the load. The program of controlling the switch is varied to optimize the ability to distinguish similar load types. The switch can be further used to control power to the load that varies according to a set of rules based upon the identity of the load. In a preferred embodiment, the design enables high efficiency with minimal components that may be fully integrated onto silicon.

  • Patent number: 11101653
    Abstract: A method for estimating an amount of solar generation capacity on a portion of the electrical grid such as a feeder. The method calculates maximum irradiance conditions for the feeder's geographic location and the time of year, and also records actual changes in electrical load measured periodically at a source over a time span such as a month. An additional analysis of active power against reactive power on the feeder is used to identify changes in load which were driven by real consumption versus those driven by changes in solar generation. A comparison of the actual changes in electrical load due to solar generation variation to the maximum irradiance curve yields a scaling factor and provides an estimate of the solar generation capacity on the feeder.

  • Patent number: 10955448
    Abstract: A system and method for detecting a high impedance fault in an electrical line strung along and between utility poles, where the line is part of an electrical power distribution network. A current sensor is provided on each line segment between the utility poles, where each current sensor harvests power therefrom and continuously monitors the current flow on the line segment. An observer/repeater device is provided on a number of the poles and each is in communication with certain select ones of the current sensors to receive the current measurements therefrom. One of the observer/repeater devices compares the current readings transmitted to it from the subordinate current sensors, and if a violation of Kirchhoff's current law exists, an indication of a high impedance fault occurs, where the observer/repeater device relays the current irregularity to an upstream recloser to take appropriate action.
