Abstract
High-performance computing (HPC) is having a profound impact on scientific discovery and engineering in a variety of areas, and researchers are beginning to demonstrate how HPC can impact problems in energy grid planning and operations. Contemporary supercomputers can perform over 10 15 floating point operations per second and have more than 1.4 petabytes of memory — roughly 5 orders of magnitude greater than a commodity PC workstation. This level of computing power changes the very nature of problems that can be solved. Researchers at LLNL have used HPC systems to accelerate execution of a renewables planning study, by solving a thousand unit commitment and dispatch problems in parallel; this generated new insights and allowed for a more detailed study than would have been otherwise achievable. Ongoing work at LLNL includes the development and testing of new parallel algorithms for unit commitment problems, including multi-scenario stochastic unit commitment. These algorithms will enable greater grid and time resolution and provide more accurate solutions because of the increase in model fidelity.
