Content Foreword

The NEIS conference of 2021 was held under special circumstances. Just like last year, the ongoing pandemic prevented us from hosting our conference the usual way. Even more so, Covid showed us once more the high importance of independent, sustainable and reliable energy supply. For over a year now, we all have been forced to adapt our research and general working environment to new and mostly virtual surroundings. Not only does this result in limited research possibilities, but also the personal exchange and the work in research groups was very restricted. This shows that, now more than ever, we need a safe, flexible and reliable energy supply to secure amongst other things also our further digital research exchange. Surely, we will also continue to have more online communication and less presence than before the pandemic.

The 9th NEIS conference in 2021 was organized with the technical support of IEEE PES Germany Chapter, of the IEEE Germany Section and with support from the Cluster Agency Renewable Energy Hamburg and 50Hertz Transmission. For the second time in a row, we had to adapt to the ongoing pandemic by hosting the conference completely online. Even though this way of scientific exchange remains unfamiliar and somewhat impersonal, this format allowed the incorporation of even more keynote presentations and webinars than usual. Also, we were able to attract more research from foreign countries, who might not have been able to attend in person. In the end, we can say that we are once more very grateful for the active participation, the interesting scientific discussions and for the very nice atmosphere that we have grown accustomed to over the years. With careful preparation and detailed planning of all eventualities, we look back on a very successful conference that fulfilled all our expectations.
Detlef Schulz received the Dipl.-Ing. in 1997 from Technical University Cottbus, Germany. From 1997 to 1999 he was with ABB Industrial Automation in Cottbus. In 2002 he received the Dr.-Ing. degree from the Technical University Berlin, Germany. The venia legendi was finished at the Technical University Berlin in 2006. From 2004 to 2005 he was a Professor for Electrical Engineering and Wind Energy at the University of Applied Sciences in Bremerhaven/Competence Center Wind Energy. Since 2005 he has been a Full Professor and the Head of the Institute of Electrical Power Systems, Helmut Schmidt University, University of the Bundeswehr, Hamburg, Germany. His research areas are electrical power systems and on-board electrical systems: grid integration and grid conformity of distributed generation and electro-mobility, grid impedance measurement, grid protection and internal electrical control of fuel cells. The research is assigned to the DLab – Distributed Energy Laboratory. He is a Full Member and since 2019 a spokesmen of the working group "Hydrogen for Northern Germany" of the Academy of Sciences and Humanities in Hamburg, a member of the VDE ETG and senior member of IEEE. Since 2013 he is Member of the Board of the Research Association Wind Energy and other Distributed Energies – FGW and since 2020 CEO of the Board of the "Grid Impedance Association".
