- W2989783330 abstract "Linear energy system models are often a crucial component of systemdesign and operations, as well as energy policy consulting. Such models can lead to large-scale linear programs, which can be intractable even for state-of-the-art commercial solvers|already the available memory on a desktop machine might not be sufficient. Against this backdrop, this article introduces an interior-point solver that exploits common structures oflinear energy system models to efficiently run in parallel on distributed memory systems. The solver is designed for linear programs with doubly borderedblock-diagonal constraint matrix and makes use of a Schur complementbased decomposition. Special effort has been put into handlinglarge numbers of linking constraints and variables as commonly observedin energy system models. In order to handle this strong linkage, a distributedpreconditioning of the Schur complement is used. In addition, thesolver features a number of more generic techniques such as parallel matrixscaling and structure-preserving presolving. The implementation isbased on the existing parallel interior-point solver PIPS-IPM. We evaluatethe computational performance on energy system models with up to 700million non-zero entries in the constraint matrix, and with more than 200million columns and 250 million rows. This article mainly concentrates onthe energy system model ELMOD, which is a linear optimization modelrepresenting the European electricity markets by the use of a nodal pricingmarket clearing. It has been widely applied in the literature on energysystem analyses during the recent years. However, it will be demonstratedthat the new solver is also applicable to other energy system models." @default.
