Abstract: A stability control method for a virtual synchronous generator (VSG) in a strong grid based on an inductance-current differential feedback is provided. A grid-connected topological structure of a VSG using the control method includes a direct-current (DC)-side voltage source, a three-phase inverter, a three-phase grid impedance and a three-phase grid. By controlling the VSG and controlling the inductance-current differential feedback, the method suppresses the oscillation of the output power from the VSG in the strong grid and implements the stable operation of an inner-loop-free VSG in the strong grid, without adding the physical inductance, increasing the cost of the filter and additionally providing a grid-side current sensor.

Abstract: The present disclosure provides a method and an apparatus for Mesh networking, and a gateway device. The method includes: monitoring a probe request frame on a target channel, wherein the probe request frame is automatically transmitted on the target channel by a gateway device to be connected in a state of no network configuration; in response to a monitored probe request frame indicating that the gateway device to be connected meets a networking condition and receiving a networking instruction, establishing a Wi-Fi Protected Setup (WPS) connection with the gateway device to be connected; and synchronizing networking configurations with the gateway device to be connected through the WPS connection, so that the gateway device to be connected is connected to the Mesh network based on the networking configurations.
