Profiles
🛈 In a specific profile, the research focus and research projects will be listed together with the membership in other research networks. Presentation of research competences and research interests is also given by profiles. Profiles can also be linked to research clusters for finding common interests and intersections between research groups.
In the finalized prototype all items for each profile are completely filled in and the current publications (including papers, data and simulation models) are also listed.

Research Projects
DEER

In the project "Decentralized Redispatch (DEER): Interfaces for Flexibility Provision", solutions for the integration of decentralized plants into the superordinate market-based redispatch process are being investigated. One focus is on modeling the flexibility of micro plants.

DERIEL

De-risking electrolyser motivation DERIEL (de-risking electrolyser) forms the link between the two aspects of series production of water electrolysers and the application of series-produced water electrolysers in an industrial environment. The prerequisite for reliable series production and a low-friction market ramp-up is a fundamental understanding of the degradation, error and interface mechanisms at all technical and economic levels. In DERIEL, the technical level is fundamentally investigated in relation to the operation of the electrolyzer up to the individual module size on a scale of 0.75 - 1 MW. All components of the electrolyzer are considered, starting with the electrocatalysts, membrane electrode assembly (MEA), cell, cell stack and electrolyzer-specific process engineering.

NFDI4Energy

The National Research Data Infrastructure (NFDI) addresses various challenges for the German science system, is to set standards and establish them in the respective subject communities in order to make the increasing amount of this data more accessible. NFDI4Energy focuses on data and software in energy system research, which are necessary, among other things, for research on forward-looking technologies related to the energy transition, increasing sector coupling, and the digitization of energy systems. This data must be traceable from the initial project idea to policy advice and should be made reusable as far as possible.

Redispatch 3.0

The "Redispatch 3.0" project aims to improve the integration of low-voltage systems and the cooperation and exchange of information between DSOs and TSOs. The aim is to further develop existing concepts from the "Redispatch 2.0" project and to implement, test and evaluate the resulting approaches on a pilot basis.

SiNED

The research project "SiNED - System Services for Secure Electricity Networks in Times of Advancing Energy Transition and Digital Transformation" aims to investigate the necessary adaptations of system services to the changed requirements due to digitalization and advanced energy transition. Solutions for the secure operation of future power grids - taking into account the special situation in Lower Saxony - are being developed and reviewed. Especially for the wind-strong regions of Lower Saxony, it is of particular importance to find improved solutions for system services to cope with fluctuating feed-in and for congestion management through electricity storage and connectable loads. Up to now, the system services (SDL) for secure operation of the power grids - e.g., control power, reactive power provision, and other grid-supporting services (instantaneous reserve, short-circuit power) - have been provided primarily by the synchronous generators of large power plants for decades. In the future, these system services will have to be provided by a large number of decentralized sources and loads in the distribution grids as part of a cross-sector energy transition. The increasing demands on the scope and resilience of the digitization of the energy system as a result of this also lead to new requirements for the economic and legal framework conditions of the future energy supply system. All necessary adjustments are being investigated due to closely networked interdisciplinary areas of expertise. In this way, both the system and grid technology and the information technology aspects of system service provision as well as the associated economic and energy law issues can be illuminated.

Wärmewende Nordwest

Digitalization for the implementation of heat transition and value-added applications for buildings, campuses, districts and municipalities in the Northwest.

ZLE

Digitization is a global megatrend that enables new functions and processes across industries and networks. In the safety-critical energy system, digitization is creating new interactions and sensitive interdependencies that on the one hand promise more efficient and sustainable operation, but on the other hand are largely unexplored in terms of their technical challenges and stability on a systemic and large scale. To research this topic, the Center for Digital Innovations Lower Saxony (ZDIN) therefore established the Future Lab "Digitization Energy" (ZLE). The goal of the ZLE is to investigate interactions in highly integrated quarter ICT and energy systems and to develop a platform for networking researchers and users to support the transfer of these and, prospectively, other research results. This results in the following two project pillars for the processing area of digitalized energy systems: I: The research and development of digitized energy systems II: The digitization of energy system research and development The elenia deals with the identification and modeling of PV, PV storage and electric mobility scenarios in the quarter scenario. A special focus is on the simultaneous multiple use of storage and the integration of smart home simulations in co-simulations to complement the purely software-based simulations with hardware components available in the elenia-energy-labs. In this context, requirement specifications for smart metering systems are also being developed, which are of particular relevance with regard to the integration of quarter ICT and energy systems in the future energy supply of Lower Saxony.

Summary
OFFIS has, since its formation in 1991, converted scientific know-how from computer science into prototypes which are then developed further into marketable products by commercial partners. Hereby, OFFIS provides research and prototype developments for companies and institutions – and this at the highest international level.
Energy, Society, Health and Manufacturing – these are the application-oriented research and development divisions that are now the OFFIS structure. The divisions are pervaded by the knowledge gained from the different fields of technology.
The result of this work takes effect on two levels: On the one hand, OFFIS has made nationally, as well as internationally, a name for itself as a Center of Excellence for chosen applied fields of computer science, and OFFIS developments are used by industries and institutions throughout the world. On the other hand, OFFIS considers itself a driving force for innovations, with concerns for regional politics through which knowledge remains in the region, and new sustainable jobs are established for northwestern Germany.
