Many Energy System Models (ESMs) result in large-scale Linear Programs (LPs) that are computationally intractable for state-of-the-art LP Solvers. BEAM-ME is a project for Economic Affairs and Energy (BMWi) that addresses the need for efficient solution strategies for ESMs. The investigated solution approaches involve changes to the formulation of the ESMs, parameter tuning to improve the performance of general-purpose LP solvers but also the development of new solution algorithms that focus on parallelization to utilize the power of High-Performance Computers (HPC). Many ESMs have a block structure that is not well exploited by general purpose LP solvers but that makes the model in general suitable for structure exploiting parallel algorithms. BEAM-ME is an ongoing research project but first results already show significant speedup potentials for particular solution approaches.
