Patent number: 11592788Abstract: The present disclosure describes systems and techniques that enhance effectiveness and efficiency of a contingency analysis tool that is used for studying the magnitude and likelihood of extreme contingencies and potential cascading events across a power system. The described systems and techniques include deploying the contingency analysis tool in a high-performance computing (HPC) environment and incorporating visual situational awareness approaches to allow power system engineers to quickly and efficiently evaluate multiple power system simulation models. Furthermore, the described systems and techniques include the power system contingency-analysis tool calculating and coordinating protection element settings, as well as assessing controls of the power system using small-signal nomograms, allowing power system engineers to more effectively comprehend, evaluate, and analyze causes and effects of cascading events against a topology of a power system.Type: GrantFiled: March 23, 2020Date of Patent: February 28, 2023Assignee: Battelle Memorial InstituteInventors: Nader A. Samaan, Bharat GNVSR Vyakaranam, Jeffery E. Dagle, Yousu Chen, Marcelo A. Elizondo, Mallikarjuna R. Vallem, Pavel V. Etingov, Qiuhua Huang, Xinya Li, Blaine J. McGary, Kirsten L. Pierce, George Chin, Jr., Dimitri V. Zarzhitsky

Patent number: 11206278Abstract: Technology related to risk-informed autonomous adaptive cyber controllers is disclosed. In one example of the disclosed technology, a method includes generating probabilities of a cyber-attack occurring along an attack surface of a network. The probabilities can be generated using sensor and operational data of a network as inputs to an attack graph. The risk scores can be determined using a plurality of fault trees and the generated probabilities from the attack graph. The respective risk scores can correspond to respective nodes of an event tree. The event tree and the determined risk scores can be used to determine risk estimates for a plurality of configurations of the network. The risk estimates for the plurality of configurations of the network can be used to reconfigure the network to reduce a risk from the cyber-attack.Type: GrantFiled: June 5, 2019Date of Patent: December 21, 2021Assignee: Battelle Memorial InstituteInventors: Arun Veeramany, William James Hutton, III, Siddharth Sridhar, Sri Nikhil Gupta Gourisetti, Garill A. Coles, Mark J. Rice, Paul M. Skare, David O. Manz, Jeffery E. Dagle, Stephen D. Unwin
