The project addresses research needs arising from the previous project INTEEVER (FKZ 03ET4020). On the one hand, this concerns the degree of abstraction and differentiation of technologies for balancing consumption and generation in the German and European electricity system, and thus the input data of the models, which have a significant impact on the results. On the other hand, the project aims for a close coupling of energy system modelling and power flow simulation in the European transmission grid.
The integration of scenario analysis will also be intensified between energy system modelling and the distribution grid level as well as with agent-based modelling. In this regard, INTEEVER II focuses on both macroeconomic and microeconomic analyses for the integration of PV battery systems and electric heat pumps, as well as for the controlled charging of battery electric vehicles and the role of decentralized hydrogen infrastructures.
Previous coupling of energy system model and power flow simulation has been based on data exchange, which requires a lot of work and allows only a limited number of integration cycles. In this project, an automated and tighter model coupling should be examined and implemented as well as options for a hard-coupling of the models on a high performance computer. The most promising approach will be implemented using a suitable integration software environment based on the data and methods developed in the project INTEEVER. Besides, the results of the BEAM-ME project (FKZ 03ET4023) will be used for this purpose. This enables both an improved solvability and a higher complexity of the applied linear programs..
In addition, it is planned to deduce suitable indicators for the assessment of security of supply within transformation paths of the energy system. Therefore, frequency and voltage stability as well as N-1 security should be considered for subsequent analyses. Moreover, also dynamic network calculations are planned to investigate these aspects in more detail.
