Patent number: 12135344Abstract: Systems and methods for voltage stability monitoring and active/reactive power support are disclosed herein. In some embodiments, a smart electric meter of an end user in a grid power system can measure the voltage supplied to the end user via the grid power system, and can analyze the voltage data to detect critical voltage characteristics. The critical voltage characteristics may indicate that a voltage collapse event is likely. The smart electric meter can further estimate a voltage stability margin based on the voltage data. If necessary, the smart electric meter can control an electrical power source and/or an electric appliance positioned at or near the end user to increase the voltage stability margin.Type: GrantFiled: August 19, 2020Date of Patent: November 5, 2024Assignee: LAWRENCE LIVERMORE NATIONAL SECURITY, LLCInventors: Liang Min, Nan Duan

Patent number: 11914937Abstract: Techniques, systems, and devices are described for providing a computational frame for estimating high-dimensional stochastic behaviors. In one exemplary aspect, a method for performing numerical estimation includes receiving a set of measurements of a stochastic behavior. The set of correlated measurements follows a non-standard probability distribution and is non-linearly correlated. Also, a non-linear relationship exists between a set of system variables that describes the stochastic behavior and a corresponding set of measurements. The method includes determining, based on the set of measurements, a numerical model of the stochastic behavior. The numerical model comprises a feature space comprising non-correlated features corresponding to the stochastic behavior. The non-correlated features have a dimensionality of M and the set of measurements has a dimensionality of N, M being smaller than N.Type: GrantFiled: February 13, 2023Date of Patent: February 27, 2024Assignees: LAWRENCE LIVERMORE NATIONAL SECURITY, LLC, VIRGINIA TECH INTELLECTUAL PROPERTIES, INC.Inventors: Xiao Chen, Can Huang, Liang Min, Charanraj Thimmisetty, Charles Tong, Yijun Xu, Lamine Mili
