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.
