Activate the Dual Cones: A Tight Reformulation of Conic ACOPF Constraints
Saba Rafiei, Samuel Chevalier
By exploiting the observed tightness of dual rotated second-order cone (RSOC) constraints, this paper transforms the dual of a conic ACOPF relaxation into an equivalent, non-conic…

GPU-Accelerated DCOPF using Gradient-Based Optimization
Seide Saba Rafiei, Samuel Chevalier
DC Optimal Power Flow (DCOPF) is a key operational tool for power system operators, and it is embedded as a subproblem in many challenging optimization problems (e.g., line switchi…

Towards Perturbation-Induced Static Pivoting on GPU-Based Linear Solvers
Samuel Chevalier, Robert Parker
Linear system solving is a key tool for computational power system studies, e.g., optimal power flow, transmission switching, or unit commitment. CPU-based linear system solver spe…
