Power-system Modeling & Control for the Era of Inverter-based Resources
Add to Google Calendar
Abstract: Power networks all over the world are experiencing dramatic upheaval in compositional form and anticipated functionality. With retirement of fossil-fuel-driven synchronous generators, integration of renewable energy, and adoption of electrified transportation, there is a pronounced change in the energy-conversion interfaces that form the backbone of the grid. Particularly, energy processing in future grids will be dominantly handled by semiconductor-based power-electronics circuits termed inverter-based resources (IBRs). This talk will provide snapshots of how classical power-system modeling problems can (and will have to) be revised to accommodate these emerging technologies. In particular, we will present insights on synchronization of IBRs with a variety of control methods, provide a system-theoretic solution to normalizing dynamic models of diverse grid assets, and overview a time-domain network-reduction method for large-scale electrical networks. Each topic will be presented with an effort to acknowledge the rich history of personalities, methods, and venues relevant to power engineering over the 20th century.
