QCQP-Net: Reliably Learning Feasible Alternating Current Optimal Power Flow Solutions Under Constraints

no code implementations11 Jan 2024 Sihan Zeng, Youngdae Kim, Yuxuan Ren, Kibaek Kim

At the heart of power system operations, alternating current optimal power flow (ACOPF) studies the generation of electric power in the most economical way under network-wide load requirement, and can be formulated as a highly structured non-convex quadratically constrained quadratic program (QCQP).

APPFL: Open-Source Software Framework for Privacy-Preserving Federated Learning

1 code implementation8 Feb 2022 Minseok Ryu, Youngdae Kim, Kibaek Kim, Ravi K. Madduri

Federated learning (FL) enables training models at different sites and updating the weights from the training instead of transferring data to a central location and training as in classical machine learning.

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).
