This is Gourab Banerjee, an M.Sc. in renewable energy (EUREC) in the year 2013-14, worked in Fraunhofer IEE, Kassel, Germany from 2015 until 2017 and then in the department of “Energiemanagement und Betrieb elektrischer Netze (e2n)” at the University of Kassel, Germany in collaboration with Fraunhofer IEE, Kassel, Germany since 2017 as a researcher. My research focus is power system protection and grounding study for distribution grids. I recently have a publication in the IEEE SEST (Smart Energy Systems and Technologies) 2019 international conference, Porto, Portugal. Kindly find the abstract of the publication as follows:

Topic of the Paper: “Protection and Dynamic Analysis during Bottom-Up Restoration Process in MV/LV Microgrids”

Motivation and State of the Art

The purpose of this research is to investigate the protection behavior during power system restoration. In
islanded mode, the network is a weak grid, and therefore, frequency and voltage deviation might be
significant in case of switching or power flow variations. Furthermore, the trend to a larger share of
inverter-based generation leads to low inertia as well as decreased short-circuit level, and can affect the
efficiency of the protection systems. So, it is important to analyze if the classical settings of protections
are feasible for the grid operation in islanded mode.
