PNNL

Elizondo is a chief power system research engineer in the Electricity Infrastructure and Buildings division at Pacific Northwest National Laboratory (PNNL), where he joined in 2009. His research encompasses a diverse range of topics from bulk electric systems planning and resilience to electromagnetic and electromechanic dynamics in distribution systems and microgrids. He leads a portfolio of projects for Department of State on regional cross-border power systems, transmission expansion, renewable integration, electricity markets, and stability analysis. He also leads projects for the Department of Energy on power system modeling for resilience, including continental-level transmission modeling and high penetration of power electronics equipment in transmission and generation sectors, and transmission and distribution resilience evaluations for grids transiting to 100% renewables. Elizondo has helped develop planning tools for dynamic cascading failure analysis (DCAT), electric grid resilience and assessment system (EGRASS), sub-transmission reactive power planning (CReST-VCT), generation flexibility assessment (GRAF-Plan), electromechanic and phasor-dynamics for distribution resilience (added to GridLAB-D), as well as for the national-scale energy resilience planning and situational awareness (NAERM). Before joining PNNL, Elizondo was an international power system consultant in Mercados Energéticos Consultores, Argentina, where he led projects on wind generation grid access, and was involved in the technical design of a new ancillary services market. He earned his engineering and PhD degrees in power systems from the Universidad Nacional de San Juan, Argentina in 2002 and 2008, respectively. He was also a graduate visiting scholar at Carnegie Mellon University from 2003 to 2005, and undergraduate visiting student at Supélec, France, in 2001.
