This is Gourab Banerjee, an M.Sc. in renewable energy  (EUREC) in the year 2013-15, worked in Fraunhofer IEE, Kassel, Germany (formerly Fraunhofer IWES) from 2015 until 2017 and then in the department of “Energiemanagement und Betrieb elektrischer Netze” at the University of Kassel, Germany in collaboration with Fraunhofer IEE, Kassel, Germany as a researcher since 2017. My research topic is related to the protection study for distribution grids focusing on the grounding protection, and now concentrating on the grid planning for distribution grids. I recently have a publication in the IEEE SEST 2018 international conference, Spain. Kindly find the summary of the publication as follows:

Introduction and Motivation

The purpose of this research is to investigate the impact of the grounding design on the high voltage end (110 kV) during a bottom-up network restoration process during the different islanding formations from black-out. Compensated grids and resonant grounding are majorly used in Germany and Middle-Europe for medium and high voltage grids. To avoid the hazardous effect of the ground fault during network restoration processes with the connection of DER, it is important to analyse how the grounding is affected by the changing topology and grid configuration. Different grid configurations are analyzed in this paper and the grounding safety range is established during the investigation process
