The electrification of the mobility sector represents a key element of the ongoing energy system transition. Together with a growing share of renewable energy sources in electricity generation,
electric mobility, as a consumer of electricity from renewable sources, can make a fundamental contribution to an extensive reduction in greenhouse gas emissions caused by the transport sector. At the same time, however, the large-scale integration of electric mobility into the energy system will also be accompanied by a significant increase in demand for electricity and results in a higher complexity of the energy system. In addition to these challenges, sector coupling offers new opportunities to provide additional flexibilities for the power grid, with electric vehicles being used as flexible storage units for grid-serving applications.

With its broad-based consortium, the unIT-e² project addresses the holistically optimized and sustainable integration of electric mobility into the energy system and the associated challenges. For this purpose, real-world laboratories are being created that focus on different regions and issues and offer stakeholders with sometimes competing interests a cross-sectoral exchange and research platform to work together on solutions under scientific supervision. The real-world laboratories will be structured in four clusters and enable the interdisciplinary development and testing of interoperable solutions with the participation of stakeholders from all sectors with interfaces to electric mobility: automotive industry, development of smart meter gateways (SMGW), grid operators, energy suppliers, development of charging stations, aggregators, software development, operators of charging stations and research.

The contributions of the researchers based at the Chair for Energy System Economics (FCN-ESE) address in particular the investigation of repercussions of electric mobility on the energy system. In order to ensure a sustainable and socially accepted renewal of the mobility sector, it is essential that the integration into the energy system proceeds without endangering the security of electricity supply for other consumers. Accordingly, it is necessary to quantify and evaluate the impact of the market ramp-up of electric mobility on the security of electricity supply in a model-based manner. For this purpose, existing probabilistic simulation models are further developed and applied with respect to different scenarios.


The assessment of the security of electricity supply is based on a comparison of electricity demand and supply over the course of the year in hourly resolution. In order to adequately map the influence of the market ramp-up of electric mobility and the associated increase in demand for electricity, taking simultaneity effects into account, it is necessary to generate synthetic load profiles at an aggregated level for the federal territory of Germany in hourly resolution. At the same time, the electrification of the mobility sector can also have a positive impact on the security of electricity supply due to the flexibility potential of charging processes. Here, the probabilistic model will be used to derive the requirements for flexibility in charging behavior that a certain level of security of electricity supply imposes on the overall system.
