This project investigates the flexibility potential of buildings to stabilize electrical distribution networks. The multiphysics simulation platform developed within the project enables the integrated calculation of a variety of possible scenarios, particularly with regard to settlement structure and development of renewable electricity generation. It can provide important insights for future planning and modification of new and existing energy systems. In particular, the assessment of grid stability, the necessary expansion of electricity distribution networks and the identification of technology pathways for buildings and system engineering represent important objectives of the project. An economic assessment of technological development paths can identify new business models and thus identify risks and opportunities for the energy industry.

To analyze the potential of the technologies to compensate for local residual load, the project develops a variable, scalable simulation environment, which has a high degree of automation. Using this environment, a large number of neighborhoods is examined, with individual parameters (number of buildings, composition, predominant system engineering, user behavior, network topology, etc.) that can be varied. Through time-resolved dynamic simulations, conclusions about the suitability of certain technologies and their optimal dimensioning and distribution depending on the considered quarters can be drawn. Furthermore, the influence of these thermal-electric plants can be analyzed for the stability of the electrical distribution network and the necessary interaction with higher grid levels. Through the investigation and assessment of a variety of different scenarios, the complexity of future decentralized energy systems is covered and improves the understanding of the system.
