InEEd-DC 3-stage optimization model sector coupling

Motivation und objective

Within the framework of InEEd-DC, a variable, parameterizable mathematical model framework for depicting and optimizing prosumers and neighborhood classes is being developed. It can be used to present a calculation and evaluation tool for the holistic consideration of all networked components in order to identify new potentials and to support companies active in the respective field in their decisions, as well as to determine boundary conditions that make sense from an urban planning perspective. The focus is on presenting different technologies, as well as the modularized illustration of DC technologies in the neighborhood, especially with regard to mobility. Only in the context of a holistic view of all coupled energy sectors an evaluation of novel, DC-based and cross-sectoral technology options is meaningful and plausible, which altogether underpins the relevance of the topic in the context of the research campus FEN.

Approach und methodology

In order to advance developments in the field of sector coupling, a new optimization environment with a special focus on DC technologies will be researched and developed in InEEd-DC. The methodology to be developed starts from the modeling of single semi-autonomous prosumers (e.g. buildings) and extends the interconnection of prosumers to larger units. The use of established mathematical methods from the research project to capture the multi-criteria solution spaces forms the basis on which a novel optimization environment will be created using accelerated model solution algorithms. In addition, information and communication technology (ICT) based control options that are technically applicable in a digitized world will be tested. Examples include instruments such as a price signal or stability indicators.

The InEEd-DC project is being funded as part of the 2nd funding phase of the FEN research campus and with the support of the jury of the "Research Campus - Public-Private Partnership for Innovation" funding initiative of the German Federal Ministry of Education and Research (BMBF) with a total sum of around 1.4 million euros over a period of five years.

To achieve the ambitious project goals, close cooperation between industry and research institutions is granted under the leadership of the research campus FEN. The participating research institutes of RWTH Aachen University are the Institute for Power Generation and Storage Systems (PGS), the Institute for Energy Efficient Buildings and Indoor Climate (EBC) and the Institute for Automation of Complex Power Systems (ACS). In addition to the RWTH's scientific collaborative partners, E.ON SE and Kiepe Electric GmbH are associated as non-funded partners in this project. In the various work packages, connecting points are defined, where a contribution is made by the associated partners with a focus on DC applications in the mobility sector and development of new business models in the project.
