  • Computer-implemented methods and systems for avoiding divergence in multi-area power grid state estimation
    Patent number: 11418057
    Abstract: Divergence of state estimation solutions for multi-area power grids typically occurs due to a single anomaly in the measurement set or network model, yet will cause failure of the state estimator to provide the solution for the entire system. Disclosed herein are methods and systems that allow detection, identification and isolation of the anomaly during the state estimation solution so that a large percentage of the system states can still be estimated, while isolating the anomaly that is causing the divergence for the estimator.
    Type: Grant
    Filed: December 11, 2020
    Date of Patent: August 16, 2022
    Assignee: Northeastern University
    Inventors: Ali Abur, Pengxiang Ren
  • Techniques for processing power system network information
    Patent number: 11176289
    Abstract: Techniques and apparatus for parameter error detection in a power system based on state estimation are described. In one embodiment, for example, an efficient process may be used to derive and compute only the necessary subset of the gain matrix and covariance matrix, thus avoiding the computation and storage of large dense matrices. The described efficient process can be applied either to single-scan or multiple-scan schemes. Other embodiments are described.
