profile：
vijay vittal was born in bangalore, india. he received the b.e. degree from the b.m.s. college of engineering, bangalore, india, in 1977; the m.tech. degree from the indian institute of technology, kanpur, india, in 1979; and the ph.d. degree from iowa state university, ames, in 1982 all in electrical engineering.
from 1982 – 2004 he served as a faculty member at iowa state university. in 2005 he joined arizona state university where he is the ira a. fulton chair professor and the asu foundation professor in power systems engineering at the school of electrical, computer and energy engineering.
his research interests are in power system dynamics, dynamic security assessment of power systems, power system operation and control, and application of robust control techniques to power systems.
during 1993-1994 he was the program director of the power systems program at the u. s. national science foundation. in 1997, he was elected as a fellow of ieee. he was the recipient of the 2000 ieee power engineering society outstanding power engineering educator award. from 1998-2000 he was the chairman of the ieee power engineering society system dynamic performance committee. he was the technical program chair for the 2001 ieee pes summer power meeting. he was elected to the u.s. national academy of engineering in 2004. in 2013 he was awarded the ieee herman halperin t&d field award. in 2018 he received the utility variable-generation integration group (uvig) achievement award and the ieee power and energy society prabha s. kundur power system dynamics and control award. in 2019 he was awarded the ieee power and energy society prize paper award.
since 2005 he has also served as the director of the power system engineering research center, a phase iii national science foundation, industry/university collaborative research center consisting of 12-member universities and 30 industry members.
abstract：
the phrase water-energy nexus is commonly used to describe the inherent and critical interdependencies between the electric power system and the water delivery system (wds). in this work, an analytical framework capturing the interactions between these two critical infrastructures is examined and a mathematical model to describe the associated dynamics is developed. based on the time-scale of the associated dynamics, the electric network behavior is represented using time-series power flows following unit commitment and optimal power flow solutions. the wds is represented using continuity equations at the delivery junction nodes and energy equations around the delivery loops and from tanks and reservoirs to the network. an integrated simulation engine of the interdependent infrastructure systems is formulated to conduct long-term simulations. test cases have been conducted to show the impact of mega droughts and electric supply disruptions on the two interdependent systems.
