Jan Sprafke then presented a test stand on which the soluble carbon (measured as COD) is separated from biowaste samples. The biowaste is exposed to various thermal and mechanical influences during defined periods using water as a solvent. Initial results are promising and corresponding follow-up tests will be carried out soon.
Science Minister Birgit Hesse visits the "Netz-Stabil" research association
During her research trip to the research alliances funded by the state's excellence research programme, the Minister of Education, Science and Culture of Mecklenburg-Western Pomerania also visited "Netz-Stabil".
After an introductory lecture by the project coordinator Prof. Dr.-Ing. Hans-Günter Eckel, she visited the Alfred-Leder-Halle. Within the scope of work package 10 "Grid stabilization by pump and fan systems", the excellent research environment in the anechoic chamber of the Chair of Turbomachinery can be used. By modifying the existing pump circuit, possible effects of grid-stabilizing pump control algorithms on the connected water supply network can be investigated. The aim is to describe the limits of such a network-related regulation.

3rd Meeting of PhD students
In addition to organisational aspects that enable a smooth running of the research project, the focus was again on technical issues. This time, the working groups “Bioenergy plants and storages" and " Framework conditions and incentive systems" presented their first results.
On 23 November 2017, this year's Forschungscamp took place in the Atrium, Konrad-Zuse-Haus. On a total of 70 posters, scientists from seven faculties and the Interdisciplinary Faculty, as well as from the University of Rostock's Medical Faculty and its associated institutes presented their research topics. Together with Prof. Bettina Eichler-Löbermann, Vice-Rector for International Affairs, Equality and Diversity Management and Prof. Rüdiger Köhling, Dean of the Interdisciplinary Faculty, Mr Christian Pegel, Minister for Energy, Infrastructure and Digitisation in Mecklenburg-Western Pomerania and patron of the 2017 Forschungscamp, embarked on an exciting journey through the fields of university research. Among other things, the tour led him to Dr Sidney Gierschner from the project "Grid stability with wind and bioenergy, storages and loads under consideration of an optimal sector coupling" (Netz-Stabil). The joint project is funded by the federal state of Mecklenburg-Western Pomerania as part of the Excellence Research Programme and deals with the stabilisation of the electrical supply grid with increasing feed-in from wind turbines and photovoltaics.
The joint project was also represented by the sub-project of the Chair of Waste and Resource Management. Dr Andrea Schüch gave interested participants an insight into the contribution of bioenergy in the country and the possibilities of biogas plants for flexible power supply.
The energy revolution is leading to the growing importance of distribution grids. The comprehensive installation of decentralised energy generation plants can provide an improved emergency supply for the critical infrastructure in off-grid operation and can also help restore power supply in the event of a breakdown.
The opportunities but also the challenges and the necessary prerequisites for such solutions were presented and discussed in the forum. In addition, results from research projects and field tests were presented and, in addition to the technical approaches, economic and legal questions were also addressed.
Dr Sidney Gierschner can incorporate the information gained into the further research of the association.
