  • Patent number: 12255452
    Abstract: A method for constructing a dynamic security region of a power grid based on an extended phase trajectory theory includes: obtaining a system transient stability condition and a power angle leading generator group by transient simulation of an initial operation point of a system; for generators in the leading generator group A, changing output of each of the generators to search for a dominant instability critical point; calculating the reciprocal of the slope of the tangent line of the trajectory of n swings of an extended phase plane based on angular velocity-angular acceleration in a fourth quadrant, and changing a small disturbance output of the generator at the dominant instability critical point to solve a sensitivity of the extended phase trajectory; and constructing a multi-modal practical dynamic security region based on the extended phase trajectory.

  • Publication number: 20240342752
    Abstract: A composition and method for a microtexture hydrophobic or superhydrophobic coating. The microtexture coating includes a coating layer disposed on a substrate with hydrophobic or superhydrophobic particles dispersed on top of or partially embedded in the coating layer to form an outer layer. The outer layer exhibits water repellant properties. Use of the microtexture coating permits large scale, durable hydrophobic or superhydrophobic coating applications. The microtexture coating is a useful for application on wind turbines, airplanes, solar panels, windows, or cooling systems.

  • Patent number: 11882566
    Abstract: A communications method includes: sending a scheduling request to a terminal device through a PDCCH, where the scheduling request indicates the terminal device to send data to a network device based on a preset time interval; in response to not receiving the data that is sent by the terminal device through a PUSCH, determining, based on measurement gap configuration information of the terminal device, whether a time point at which the terminal device does not send the data is within a measurement gap window; and if it is determined that the time point at which the terminal device does not send the data is within the measurement gap window, sending, to the terminal device, a redundancy version number used for a next HARQ retransmission.
