NEIS 2021

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.
