  • Patent number: 10971949
    Abstract: A method for performing energy management for a building includes generating a stack of energy loads representative of a plurality of building energy loads. The energy loads are prioritized from highest priority energy loads to lowest priority energy loads. The prioritized energy loads are then compared to a building power threshold. The lowest priority energy loads are shed until a sum of remaining energy loads is equal to or less than the building power threshold. The remaining energy loads are serviced. The processes of prioritizing the energy loads, comparing the prioritized energy loads to a building power threshold, and shedding the lowest priority energy loads is repeated in response to changes in circumstances affecting the building.

  • Publication number: 20200358283
    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.
