SC Lab

Scientific Computing Lab

The SC Lab brings together key competencies in scientific computing relevant to the mathematical modeling, simulation, and optimization of cross-sector energy systems. The SC Lab develops methods and software solutions in the areas of co- and real-time simulation of multi-energy systems, improved forecasting methods for renewable energies, efficient optimization algorithms for complex energy grids, and multi-scale modeling and simulation of power-to-X technologies. Furthermore, the SC Lab provides advisory and operational support to the EIZ facilities in all aspects of mathematical modeling, data analysis, high-performance computing, and the structured documentation and archiving of scientific data. The goal is the provision of robust, scalable and practical computing tools for energy and systems research.

Background and objectives

The European languages are members of the same family. Lor separately exists and is a myth. Por scientie, musica, sport etc, litot Europe usa li sam vocabulary. Li lingues differe solmen in li grammatica, li pronunciation e li plu common vocabules. Omnicos directe al desirabilite de a new lingua franca:
On refusa continuar payar custosi traductores. At solmen va esser necessary far uniform grammatica, pronunciation e plus sommun paroles. Ma quande lingues coalesce, the grammatica del resultant lingue es plu simple e regulari quam ti del coalescent lingues. The new lingua franca is more simple and regular than it exists in European languages. It is simply as Occidental in fact, it is Occidental. A un Angleso it va semblar a simplificat Angles, quam a skeptic Cambridge amico dit me que Occidental es.
