ET PES/PELS Joint Chapter Invited Talk - Concerns Related to DER Integration


Please join us as we invite Dr. Xiaojie (Jane) Shi to give a technical talk on some of the major concerns arising from the integration of distributed energy resources (DER).

Today, DER such as solar photovoltaic (PV) and battery storage play a significant role in the electric grid. As the penetration of these intermittent energy resources increases, there is a concern that their variable power output and high-frequency injection may bring power quality challenges like flicker and harmonics to grid-served customers. In addition, enabled by DER inverters, it is possible for a portion of the grid to remain energized when not intended. This, however, can have serious consequences such as jeopardizing safety of line workers and the public, exposure of utility equipment and controls not designed for islanded operation, and risk of damaging DER inverters due to out-of-phase reclosing. This presentation will shed light on these concerns, and evaluate the impact of DER inverters on the traditional grid as well as their capabilities on the prevention of unintended islanding operation.



Xiaojie (Jane) Shi received her M.S. degree from Zhejiang University, Hangzhou, China, in 2011, and Ph. D degree from the University of Tennessee, Knoxville, in 2015, both in electrical engineering. She was a Research Assistant Professor with the University of Tennessee, Knoxville, from 2016 to 2017. Since 2017, she has been an Engineer/Scientist II at the Electric Power Research Institute (EPRI), Knoxville, TN. Dr. Shi has authored/coauthored over 60 publications in international conferences and journals, two book chapters, and five patents pending. Her research interests include integration of distributed energy resources, microgrid, high power grid-connected converters, and HVDC transmission systems.
