  • Patent number: 10734810
    Abstract: A method for providing frequency load shedding in a power distribution network. The network includes a number of distributed switch-gear assemblies that control whether AC power is provided to groups of loads. The distributed switch-gear assemblies monitor the frequency of the AC signal to determine if a frequency event is occurring and also determine the direction of the power flow at the time of the event. The switch-gear assembly may open in an underfrequency event only if the loads are drawing power from the network, and the switch-gear assembly may open in an overfrequency event only if there is reverse power flow during the event. In addition, the order of operation of which switch-gear assemblies may open first in response to the frequency event is determined in advance by the location of the switch-gear assembly in the network and a corresponding time delay and coordinated frequency set-points.

  • Patent number: 10622837
    Abstract: When a vehicle approaches a parking space, a ground controller excites a power transmission coil using an excitation pattern signal containing identification data, and a vehicle controller acquires the identification data from the excitation pattern signal received by at least one of subcoils. Then, a communication unit transmits the acquired identification data to the ground unit. The ground controller pairs the power transmission coil and the power reception coil with each other when the identification data contained in the excitation pattern signal and the identification data transmitted from the vehicle controller match each other. Also, the pairing is canceled if the identification data received by the subcoil provided on the front side and the identification data received by the subcoil provided on the rear side are different from each other.
