Ein offenes netzebenen- und sektorenübergreifendes Planungsinstrument zur Bestimmung des optimalen Einsatzes und Ausbaus von Flexibilitätsoptionen in Deutschland - Projektabschlussbericht

The transformation of the energy system is a key task of our time. In order to investigate the challenges and opportunities of this transformation, qualified and open energy system models and planning tools need to be created and applied. The eGo^n research project addressed these tasks. It thereby pursued a comprehensive open source and open data strategy so that all data, tools and results are available under free licences.

The data model created as part of the project includes the coupling of electricity grid models over all voltage levels with a gas grid model, demands and flexibilities from the mobility, heat and hydrogen sectors as well as the integration of other electrical flexibilities. It is characterized by a high spatial resolution within Germany, while surrounding countries are considered in an aggregated form.
The developed cross-voltage-level planning tool eGo enables the determination of a cost-optimized energy system. It combines the planning tools eTraGo and eDisGo in a top-down approach.
Both tools contain various innovative methods for the adequate reduction of complexity in spatial and temporal dimensions in order to enable both calculations with sufficient accuracy and acceptable computing resources.

The analyses carried out show that integrated planning of the electricity, heating, gas and mobility sectors as well as all voltage levels are essential to be able to map their various interactions and obtain efficient, cost-effective systems. Further, by quantifying grid and storage expansion requirements in various scenarios, the relevance of the activation of flexibility to better integrate renewable feed-in and thus reduce CO2 emissions, system costs and dependence on energy imports is shown.
