How to speed-up computing time of energy system models: Key findings from the BEAM-ME project

This paper provides results from the BEAM-ME project. The project was conducted by an interdisciplinary team of energy modelers, software developer, experts in high performance computing and operation research. One aim of the project was to develop a novel approach for distributed computing and application of energy system models to high performance computing. Further the project investigated conceptual speed-up methods. In this paper we provide an overview of the main lessons learned from the different approaches. It outlines difficulties that arise for modelers when applying energy system models based on linear programming on large scale distributed machines. Further it offers suggestions for modelers how speed-up of energy system models could be reached from a modelling perspective. The BEAM-Me project is funded by the German Ministry of Economic Affairs and Energy.
