Official code, datasets, and numerical results for a solver-oriented AC Optimal Power Flow framework.
This repository provides implementations and numerical evaluation tools for an alternative AC Optimal Power Flow (AC OPF) formulation developed to improve numerical behavior when solved with interior-point nonlinear programming methods.
The framework is designed to integrate seamlessly with standard OPF toolchains and enables systematic evaluation of solver performance, robustness, and scalability across a wide range of benchmark power-system networks.
