On the Choice of Loss Function in Learning-based Optimal Power Flow
Ge Chen, Junjie Qin
We analyze and contrast two ways to train machine learning models for solving AC optimal power flow (OPF) problems, distinguished with the loss functions used. The first trains a m…
Mobile Energy Storage in Power Network: Marginal Value and Optimal Operation
Utkarsha Agwan, Junjie Qin, Kameshwar Poolla +1
This paper examines the marginal value of mobile energy storage, i.e., energy storage units that can be efficiently relocated to other locations in the power network. In particular…
Weighted Difference Approximation of Value Functions for Slow-Discounting Markov Decision Processes
Yin-Lam Chow, Junjie Qin
Processes (MDPs) often require frequent decision making, that is, taking an action every microsecond, second, or minute. Infinite horizon discount reward formulation is still relev…
Distributed Online Modified Greedy Algorithm for Networked Storage Operation under Uncertainty
Junjie Qin, Yinlam Chow, Jiyan Yang +1
The integration of intermittent and stochastic renewable energy resources requires increased flexibility in the operation of the electric grid. Storage, broadly speaking, provides…
