Development of an electricity, heat and mobility concept at district level under consideration of sector coupling for the Lagarde Campus Bamberg

摘要

The integration of electricity and heating systems as well as a large number of electric vehicles into existing grid infrastructure represents a challenging task for urban grid operators and energy service providers, but also offers flexibility potentials. The conversion process of the former Lagarde barracks in Bamberg depicts a blueprint for development of an integrated energy system. A conceptual design of a multi-energy system for the heat and power supply of a city district of approx. 20 ha. in the middle of already existing urban grid structures is presented. This covers the electrification of the heat generation including a district heating grid, the integration of high penetration of electric vehicles and PV systems, as well as the integration of a thermal storage under consideration of the overall system performance regarding CO_2 emission and costs. The feasibility of a cross-sector implementation within the framework of the ambitious goals from the BMWi's funding context "Warmenetze 4.0" will be examined. This includes both an analysis of possible energy concepts from a technical and economic point of view, as well as an examination of the non-technical needs and acceptance of future residents and various stakeholders.
