My research area is resilient operation of the electricity networks. Several initiatives such as integration of Distributed Energy Resources (DERs), demand management (DEM), smart metering, etc. have also made the smart grid networks more susceptible to both reliability failures such as faults and security failures such as cyber-physical attacks. I have modeled these failure scenarios as attacker-defender games, and formulated multi-level optimization problems to determine optimal attacker and defender strategies. I am particularly interested in the utilization of the DERs for resilient operation of the smart grid. I am interested in developing decision support tools to help quickly identify failure scenarios, determine optimal response strategies, and use them to minimize the impact on smart grid operations.
