Ongoing Research Project

In the course of the energy transition, the share of power converter-based generation plants in the electricity grid is increasing rapidly, while at the same time conventional power plants are being taken off the grid. This poses new challenges for system stability, in particular due to the disconnection of conventional grid-forming plants and the reduction of the effective short-circuit ratio. The German Federal Ministry for Economic Affairs and Energy (BMWE) roadmap for system stability stipulates that power converter-based systems must also contribute to grid stability in the future. In order to gain practical experience with GFMIs in real distribution grids at an early stage, the SUREVIVE project is conducting a field test with several decentralized GFMIs. The pilot systems will be connected at the HV/MV substation level, where the first grid-forming systems will be introduced via market-based procurement processes starting in 2025. Starting in 2027, comprehensive integration of grid-forming systems is also planned through the specification of minimum technical requirements. | Laufzeit: 01/2023 - 12/2026

The heating and cooling supply systems of buildings are usually documented in schematics. These documents contain important information about the topology and the components of the systems that are useful for designers, building managers, and technical monitoring service providers along the complete building life cycle. However, these schematics are often only available in paper form, as CAD or pdf files and the information that they contain is almost not accessible digitally. This situation makes the data collection tedious and hampers the efficiency and cost-effectiveness of refurbishment or a technical monitoring projects. | Duration: 01/2023 - 12/2025

Currently, more than half of German households are heated by gas and oil boilers. In addition to a dramatic dependence on fossil fuels, this accounts for over 50% of the energy consumption of the entire heating supply. Thanks to their efficiency, electric heat pumps (HPs) are significantly more climate-friendly and, when operated with electricity from renewable energy sources, can make a significant contribution to decarbonizing the heat supply and moving away from fossil fuels. In addition, the use of environmentally friendly refrigerants such as propane (R290) or butane (R600) is increasingly being enforced by law. Due to the high flammability of these refrigerants, permanent, technical tightness is becoming the focus of current heat pump developments. | Duration: 08/2023 - 07/2027

Project in the business areas Energy Efficient Buildings; Power Electonics, Grids and Smart Systems; Topics: Ventilation and Air-Conditioning; System Integration - Electricity, Heat, Gas; Heat Pumps; Duration: December 2014 - September 2019

In the project » Integration of heat pumps in existing buildings with a focus on craftsmen«, Fraunhofer ISE, on behalf of the City of Freiburg and financed by the Zukunftsfonds Klimaschutz (Future Fund for Climate Protection), is supporting six companies from the sanitary, heating and cooling trades in Freiburg and the surrounding area in the installation and planning of heat pumps. Fraunhofer ISE staff documents the processes and then compares the process descriptions with each other to derive best practice methods. These findings will then be disseminated through the communication channels of the project partners. | Duration: 01/2023 - 12/2024

The EQWIN-P research project aims to improve the price-performance ratio of energy-efficient buildings by increasing the degree of automation in the processing of building envelope data. So far, building envelope data are processed within a software application, but usually the data are not compatible between different applications. They must therefore be transferred manually or in broken digital chains. This includes numerous proprietary formats, some of which are also only interpretable in certain knowledge contexts. In addition, many highly complex measurement data only acquire added value for planning purposes through algorithms, so that there is an urgent need to make relevant methods for evaluating building envelopes available to the broad market as uniformly as possible. | Duration: 01/2023 - 06/2026
