Physics-Informed Tensor Completion with Application to Distribution System State Estimation
Alexander While, Anil Aswani, Chen Chen +1
State estimation in power distribution networks often involves sparse, noisy, and heterogeneous measurements, making classical weighted least-squares methods unreliable in low-obse…

An Alternating Primal Heuristic for Nonconvex MIQCQP with Dynamic Convexification and Parallel Local Branching
Yongzheng Dai, Chen Chen
We develop a novel primal heuristic for nonconvex Mixed-Integer Quadratically Constrained Quadratic Programs (MIQCQPs). The method is built around a convex approximation that is dy…
