Extended horizon methodology improves LDES dispatch efficiency in high VRE grids.
Résumé
This study compares traditional and extended horizon methods for optimizing long-duration energy storage (LDES) dispatch in renewable-dense grids. The extended horizon approach shows superior performance despite longer solution times, reducing degenerate solutions. Trade-offs between computational efficiency and storage dispatch improvement are highlighted. Degeneracy issues in high VRE systems impact revenue outcomes for LDES operators. Refinement of modeling techniques is crucial for future energy systems.
Stats
The difference between the total production cost for traditional and extended horizon runs is $89M.
PowerSimulations storage dispatch for LDES and SDES is higher by 3020 GWh and 2731 GWh, respectively, in the traditional simulation.
PowerSimulations stores significantly more energy compared to PLEXOS, affecting VRE generation and thermal generation costs.
