Power Grid Behavioral Patterns and Risks of Generalization in Applied Machine Learning

no code implementations21 Apr 2023 Shimiao Li, Jan Drgona, Shrirang Abhyankar, Larry Pileggi

Recent years have seen a rich literature of data-driven approaches designed for power grid applications.

Towards Practical Physics-Informed ML Design and Evaluation for Power Grid

1 code implementation7 May 2022 Shimiao Li, Amritanshu Pandey, Larry Pileggi

This work formalizes a new concept of physical interpretability which assesses how a ML model makes predictions in a physically meaningful way and introduces an evaluation methodology that identifies a set of attributes that a practical method should satisfy.

Circuit-theoretic Line Outage Distribution Factor

no code implementations16 Apr 2022 Shimiao Li, Amritanshu Pandey, Larry Pileggi

This work presents the design of AC line outage distribution factor created from the circuit-theoretic power flow models.

A Convex Method of Generalized State Estimation using Circuit-theoretic Node-breaker Model

no code implementations29 Sep 2021 Shimiao Li, Amritanshu Pandey, Larry Pileggi

An accurate and up-to-date topology is critical for situational awareness of a power grid; however, wrong switch statuses due to physical damage, communication error, or cyber-attack, can often result in topology errors.

Combined Transmission and Distribution State-Estimation for Future Electric Grids

no code implementations14 May 2021 Amritanshu Pandey, Shimiao Li, Larry Pileggi

Instead, a more distributed yet coordinated approach for grid operation and control will emerge that models and analyzes the grid with a larger footprint and deeper hierarchy to unify control of disparate T&D grid resources under a common framework.

Dynamic Graph-Based Anomaly Detection in the Electrical Grid

1 code implementation30 Dec 2020 Shimiao Li, Amritanshu Pandey, Bryan Hooi, Christos Faloutsos, Larry Pileggi

Given sensor readings over time from a power grid, how can we accurately detect when an anomaly occurs?
