Real-Time Risky Fault-Chain Search using Time-Varying Graph RNNs
Anmol Dwivedi, Ali Tajer
This paper introduces a data-driven graphical framework for the real-time search of risky cascading fault chains (FCs) in power-grids, crucial for enhancing grid resiliency in the…
RL for Mitigating Cascading Failures: Targeted Exploration via Sensitivity Factors
Anmol Dwivedi, Ali Tajer, Santiago Paternain +1
Electricity grid's resiliency and climate change strongly impact one another due to an array of technical and policy-related decisions that impact both. This paper introduces a phy…
Cascading Failure Prediction via Causal Inference
Shiuli Subhra Ghosh, Anmol Dwivedi, Ali Tajer +2
Causal inference provides an analytical framework to identify and quantify cause-and-effect relationships among a network of interacting agents. This paper offers a novel framework…
Blackout Mitigation via Physics-guided RL
Anmol Dwivedi, Santiago Paternain, Ali Tajer
This paper considers the sequential design of remedial control actions in response to system anomalies for the ultimate objective of preventing blackouts. A physics-guided reinforc…
GRNN-based Real-time Fault Chain Prediction
Anmol Dwivedi, Ali Tajer
This paper proposes a data-driven graphical framework for the real-time search of risky cascading fault chains (FCs). While identifying risky FCs is pivotal to alleviating cascadin…
