EE Faculty Colloquium: Development of Parallel Solvers for Bulk Power Systems Time Domain Simulations

Title: Development of Parallel Solvers for Bulk Power Systems Time Domain Simulations

Speaker: Dr. Gurunath Gurrala, Associate Professor, Dept of Electrical Engineering, Indian Institute of Science

Venue: MMCR, EE

Time: 4 pm, Friday, 20 September 2024

Abstract:
This talk introduces two different time domain simulation paradigms, phasor domain, and electromagnetic transient simulations, typically used for bulk power systems simulation. It also introduces other simulation approaches explored in the literature and compares computational aspects. Motivates the audience about the need to converge these paradigms due to the penetration of renewable sources. Computational challenges that arise in this convergence will be discussed. Introduces the need for realistic modeling of the practical power systems for cascading failure analysis and associated computing challenges. The need for scalable parallel algorithms to speed up the time domain simulations will be discussed. Introduces efficient PARALLEL algorithms and modeling approaches developed by the PhD students of the Grid Control Automation and Modelling Lab (GridCAM), EE, IISc in the past 5 years.
