Emma Stewart completed her undergraduate degree in Electrical and Mechanical Engineering from the University of Strathclyde in 2004 and a PhD in Electrical Engineering in 2009. Her field of research included the electrical integration of hydrogen and renewable technologies to power systems and she spent a period of three years at Sandia National Laboratories as a visiting researcher. She joined BEW Engineering (now DNV KEMA) as a Power Systems Engineer in March 2009 and held the position of Senior Engineer in the Transmission and Distribution team. Dr. Stewart led distribution modeling and analysis and high renewable penetration studies for customers such as Hawaiian Electric Companies and Sacramento Municipal Utilities District and was a major contributor for both CSI RD&D 1 and 3 for these two utilities. During this work, Emma developed methodologies for quantifying high penetration of PV impacts on feeders, including transient analysis, flicker studies, voltage regulation and protection studies. Emma's focus is on distribution modeling and she is an expert in the use of numerous software packages including SynerGEE Electric, PSS/Sincal, PowerWorld and PSLF. Dr. Stewart joined Lawrence Berkeley National Laboratories in 2013, and is currently engaged in distribution measurement and analysis techniques for smart grid applications.

This publications database is an ongoing project, and not all Division publications are represented here yet.
