The integration of large shares of spatially and temporally distributed fluctuating energy resources, dependent on the supply, is an increasing challenge for the future of energy management. In order to integrate renewable energies into the power system while ensuring a stable supply at the same time, an extensive adjustment of the existing energy infrastructure is necessary.

Therefore, energy storage, inter-regional power transmission, demand side management as well as a flexible power generation will play a major role for the energy supply in the future. The main objective of the project INTEEVER is the investigation of the importance of these flexibility options on a regional, national and European level applying an integrated modelling approach. For this purpose the cooperation of DLR, IFK and IEE brings together experts in the fields of scenario development and energy system modelling.

In the contribution of Fraunhofer IEE, the main focus will be on the network planning and cost-effective grid expansion in the distribution grid level. In this context, local storage systems (for households as well as central batteries for a distribution grid level) will be particularly evaluated as a possible technology for reducing the need for classical grid reinforcement. In addition, the mutual influence of batteries on the upstream grid levels will be investigated.
