This repo contains the code for implementing a parallel and GPU-accelerated large-scale, high-resolution macro energy system model for the ASEAN power grid in Southeast Asia based on GridPath.

It contains three folders. "gridpath-2026" contains the code for baseline and the solver-parallel method; "gridpath-2026_Hybrid" contains the code for the serial-parallel hybrid Benders' decomposition method; "gridpath-2026_NVIDIA_cuOpt" contains the PDLP/Barrier implementation of NVIDIA's cuOpt based on Pyomo.
