All-in-one renewable energy supply

The Press and Communication Office published a news article on the university’s home page about our participation in the project “RENBuild”, which started in January this year. Goal of the project funded by the German Federal Ministry for Economy Affairs and Energy for a duration of four years is the development and monitoring of an overall system for the combined regenerative supply of buildings with heat, cold, electricity and fresh air.

We are excited about the university’s interest in our research topics and would like to share the article here (in German).

Kick-Off-Meeting RENBuild in Würzburg

On February 12th, KET management board member Matti Grabo (FVT) visited ZAE Bayern in Würzburg to take part in the kick-off meeting of the project RENBuild. With the project partners from industry (PA-ID, Neuberger, Ratiotherm, Hölscher, Renz, Hanse Haus and ESDA) and academia (Responsible Manager Jülich, ZAE Bayern) the development and monitoring of an overall system for the combined regenerative supply of buildings with heat, cold, electricity and fresh air were discussed. Matti Grabo presented the KET and its tasks in the project, which officially started on January 1st, 2020 and is funded by the Federal Ministry for Economic Affairs and Energy (BMWi) with up to € 235,000 for a four-year duration.


"Microgrid Forum: The Energy Infrastructure of the Future" - Kick-off event at Paderborn University

On December 2nd, the kick-off event for the “Microgrid Laboratory” project took place at Paderborn University. The Department of Power Electronics and Electrical Drives (LEA) and KET in cooperation with Energie Impuls OWL invited participants from industry, research and politics to the lecture hall L. Project goals and opportunities for participation were presented. The participants also discussed the potential that the Microgrid Laboratory offers for intelligent energy systems of the future.

Under the leadership of the LEA department, KET develops the infrastructure which can be used to simulate the behavior of battery storage, wind turbines or combined heat and power plants in the laboratory. The Microgrid Laboratory in Paderborn creates a platform for future research and development projects to test and verify new innovative concepts under realistic conditions. This also strengthens the competitive position of the local industry.

New junior professorship for KET

The profile of KET will be sharpened with a junior professorship initiated and co-funded by WestfalenWIND GmbH. The focus of the new professorship will be on energy system technology, which addresses the integration of renewable energies into existing energy networks and the coupling of the electricity, heat and mobility sectors. The corresponding appointment procedure will be finished soon. WestfalenWIND will grant € 70,000 per year to set up and finance the new professorship, which will be incorporated into the Faculty of Electrical Engineering, Computer Science and Mathematics. The remaining funding is provided by Paderborn Unversity.


KET receives EFRE.NRW 3.5 Mio. € funding for Microgrid-Laboratory

KET successfully applied for the 4th round of the EFRE.NRW funding competition "Research Infrastructures". Under the leadership of the Department of Power Electronics and Electrical Drives (LEA), the concept "Microgrid Laboratory - Energy Infrastructure of the Future" was submitted in spring this year and has recently been suggested for the final project proposal submission. Six concepts were selected from a total of 21 applications, while KET's Microgrid Laboratory obtained a large part of the total € 15 million budget,with a project volume of around € 4 million and a funding sum of € 3.5 million. After submission of the formal documents, the three-year project is expected to start in spring 2019.


KET awarded for two projects at KlimaExpo.NRW

KET was awarded for two projects at KlimaExpo.NRW, thus making a critical contribution to the energy transition in North Rhine-Westphalia. The Chair of Thermodynamics and Energy Technology (ThEt) of Prof. Vrabec achieved the reduction of the energy consumption of household refrigerators by up to 17 percent with the project "Efficient Refrigerators" using latent heat and cold storage based on integrated phase-change materials (PCM). The project "Power to Heat OWL", which was carried out by the Department of Power Electronics and Electric Drive Technology (LEA) by Prof. Böcker, successfully demonstrated that the intelligent control of heating systems can adapt the electricity consumption to the fluctuating electricity production from renewable energies and thus reliving the electricity grids. KlimaExpo.NRW is an initiative of the NRW state government and awards positive examples of climate protection in North Rhine-Westphalia until 2022.

Project „MoLaWS“ successfully started

In cooperation with ESDA Technologie GmbH, the project MoLaWS - "Development of a modular heat storage system using high-capacity, innovative latent heat storage elements " has been successfully started with a kick-off meeting at Paderborn University. The aim is to develop a new, modular, air-guided heat storage system consisting of innovative low-pressure-loss and cascadable high-performance latent heat storage elements. The aim is to adapt the heating and cooling supply to the current demand and to minimize the cost-intensive consumption of electricity and fossil fuels. The focus of KET is on the modeling and CFD-based investigation of the heat transfer processes induced by the phase change as well as on the design of the heat storage elements in regards to optimal heat transfer. The project is funded by the German Federal Ministry for Economic Affairs and Energy (BMWi) as part of the Central Innovation Program for SMEs (ZIM) with €188,690.

Increasing the lifetime of PV-Modules

KET has started the €535,000 funded project “SoLifE”
In cooperation with Solarword AG and ESDA Technologie GmbH, KET started a project aimed at increasing the lifetime of PV-modules. Within the next three years, the practical integration of phase-change materials into the next generation of PV-modules will be investigated under the coordination of Prof. Dr. Stefan Krauter. The main factors contributing to the degradation of the modules can be limited using targeted cooling and temperature stabilization of the solar cells. The German Federal Ministry for Economic Affairs and Energy (BMWi) supports this project by contributing €535,000.

“Storages from North Rhine-Westphalia for a step change in the Energy Sector” at a NRW parliament event on 30.10.2015

KET discussed the topic of energy storages with representatives from research, industry, and parliament and presented ongoing projects; for example “Intelligent Domestic Appliances as Virtual Large-Scale Consumers.”
