This talk will present our research group¹s efforts on accelerating dynamics (transient stability) simulation of very large-scale power grids. Using scalable numerical solvers and adaptive time-stepping, our preliminary work shows that real-time simulation of large-scale power grids (tens of thousands of buses) is achievable. This talk will also cover basics on high-performance computing for power system analysis and an introduction to the open-source numerical library 'Portable Extensible Toolkit for Scientific Computing¹ (PETSc) will be presented.
Shrirang Abhyankar is a staff scientist in the Energy Systems Division at Argonne National Laboratory. Prior to this position, he was a post-doctoral appointee in the Mathematics and Computer Science Division at Argonne National Laboratory. He received M.S. and Ph.D. degrees from Illinois Institute of Technology in 2011. His research interests include high-performance computing techniques for power system analysis, combined transmission-distribution simulation, and power system visualization. Since 2009, he is a developer of the high performance numerical library Portable Extensible Toolkit for Scientific Computing.
