Biography

Sai Pushpak joined Pacific Northwest National Laboratory (PNNL) in 2018. Currently, at PNNL, he is working on effective utilization and integration of Distributed Energy Resources (DERs) for normal stable operation and also to provide service during extreme events. Prior to joining PNNL, he was a research assistant at Iowa State University where he focused on understanding the effect of parametric uncertainty, communication/sensor uncertainty in networked dynamical systems and applied it to understand various problems in power systems. Most importantly, he worked on the stochastic small-signal stability of power network with uncertain wind generation. Further, he developed a sparsity promoting algorithm to achieve power-sharing among generators in a Microgrid. In 2017, he was an intern at PNNL where he worked on the demand side control to achieve frequency regulation.
