  • Patent number: 11462909
    Abstract: A method for identifying report triggering events in a power grid to improve stability in the power grid is provided. Energy flow information in the power grid is measured and report triggering events during a predetermined period of time are identified. The report triggering events include at least a predetermined number of load flow transitions where energy flows back from a load associated with the power grid to the power grid during the predetermined period of time and/or exceeding a threshold of time where an energy flow phase angle between voltage and current remains at or near 90 or 270 degrees indicating pure volt-ampere reactive (VAR) operation during the predetermined period of time. A report associated with each of the identified report triggering events is generated and includes a location indicating where the report triggering event occurred in the power grid. The reports are transmitted.

  • Patent number: 11362545
    Abstract: An apparatus is disclosed for a hybrid foreign-object detection and position system. In an example aspect, a foreign object detection (FOD) system of the base power-transfer system detects a passive beacon of an electric vehicle power-transfer system based on a beacon loop of the passive beacon overlapping an array of FOD sense loops effective to cause a change in impedance or admittance of one or more of the FOD sense loops. In aspects, the impedance reflects a modulation signal from the passive beacon. A position detection system integrated with the FOD system determines a passive beacon response in the input data based on the modulation frequency from the passive beacon. Then, a position of the beacon loop is determined relative to the array of FOD sense loops using a result of the passive beacon response canceled from input data.
