Long Duration Battery Sizing, Siting, and Operation Under Wildfire Risk Using Progressive Hedging

no code implementations18 Apr 2024 Ryan Piansky, Georgia Stinchfield, Alyssa Kody, Daniel K. Molzahn, Jean-Paul Watson

Extending traditional progressive hedging techniques, we consider coupling in both placement variables across all scenarios and state-of-charge variables at temporal boundaries.

Sharing the Load: Considering Fairness in De-energization Scheduling to Mitigate Wildfire Ignition Risk using Rolling Optimization

no code implementations13 Apr 2022 Alyssa Kody, Amanda West, Daniel K. Molzahn

However, there may be many combinations of power lines whose de-energization will result in about the same reduction of system-wide wildfire risk, but the associated power outages affect different communities.

Optimizing Transmission Infrastructure Investments to Support Line De-energization for Mitigating Wildfire Ignition Risk

no code implementations18 Mar 2022 Alyssa Kody, Ryan Piansky, Daniel K. Molzahn

To reduce wildfire ignition risks, power system operators preemptively de-energize high-risk power lines during extreme wildfire conditions as part of "Public Safety Power Shutoff" (PSPS) events.

A Reinforcement Learning Approach to Parameter Selection for Distributed Optimal Power Flow

no code implementations22 Oct 2021 Sihan Zeng, Alyssa Kody, Youngdae Kim, Kibaek Kim, Daniel K. Molzahn

We train our RL policy using deep Q-learning, and show that this policy can result in significantly accelerated convergence (up to a 59% reduction in the number of iterations compared to existing, curvature-informed penalty parameter selection methods).

Modeling the AC Power Flow Equations with Optimally Compact Neural Networks: Application to Unit Commitment

no code implementations21 Oct 2021 Alyssa Kody, Samuel Chevalier, Spyros Chatzivasileiadis, Daniel Molzahn

Nonlinear power flow constraints render a variety of power system optimization problems computationally intractable.
