Modern power systems are increasingly complex. The current trend is in the growing penetration of renewables. The evolution path is often through the integration of modern technologies based on power electronics devices. Such devices require accurate circuit-based simulation methods such as those used for the computation of electromagnetic transients in power systems. The circuit-based approach is now extending into the simulation and analysis of electromechanical transients. The research on more accurate and more efficient simulation methods is increasingly more challenging within the context of large scale power systems with renewables.
This presentation is on various techniques for accelerating the computation of power system electromagnetic transients. Such techniques include research on model performance, frequency dependent network equivalents, waveform relaxation, interfacing of different domain methods and parallelization. In several approaches the automation of tasks and accuracy control remain complex.
Research on parallelization through sparse matrices is emphasized through the presentation of methods and applications for large scale power system benchmarks. It includes research on efficient re-factorization methods with nonlinear models and other time-varying models.
Biography: Jean Mahseredjian received the Ph.D. degree from the Polytechnique Montreal, Canada, in 1991. From 1987 to 2004, he was at IREQ (Hydro-Québec) working on research and development activities related to the simulation and analysis of electromagnetic transients. In December 2004, he joined the Faculty of Electrical Engineering at Polytechnique Montreal.
