  • Method and device for accessing a network hotspot device by an unconfigured device
    Patent number: 11490323
    Abstract: Embodiments of the present disclosure provide methods and devices for accessing a network hotspot device by an unconfigured device. The network hotspot device is configured to create a first hotspot and a second hotspot. The method can include reporting, by the unconfigured device, device information of the unconfigured device to one or more network hotspot devices through the first hotspot of the one or more network hotspot devices for sending the device information to a server.

  • Systems and methods for hybrid dynamic state estimation
    Patent number: 11119462
    Abstract: A power system energy management system with dynamic state estimation (DSE) is disclosed wherein system dynamic states are estimated using SCADA measurements, PMU measurements, signals of controllers, digital recorders, protection devices, and smart electronic devices. The DSE is solved first by Unscented Kalman Filter, and if the Unscented Kalman Filter is failed, weighted lease square is used to solve the DSE. If weighted lease square is failed, integration method is used to calculate the dynamic states. In another aspect, Unscented Kalman Filter, weighted lease square, and integration calculation are applied to solve the DSE by nodal parallel computing for each generation system.
