Renewable energies are the key to a sustainable and climate-friendly energy supply. However, the volatility and supply dependency of generation requires new technical and economic concepts for far-reaching integration. Sector coupling is becoming increasingly important in this context, as interconnected energy sectors open up a large field of possible energy supply paths, within which the efficiency of the overall system is increased by utilizing the inherent storage capacity of the individual sectors.
The EffiziEntEE project is about developing a modern market design that optimally exploits the flexibility of the integrated energy system. Project partners are various institutes of the Hamburg University of Technology (TUHH) and the Technische Universität Dresden. The object is to develop a multi-layer optimization for operation. In the higher layer, the schedule for the following day is first calculated using a market model, which includes a simplified steady-state network model for the electrical transmission network. This already includes congestion management measures based on load flow calculations taking into account actor behavior, power-to-X technologies and the flexibility of representative distribution grid models. In the second layer of the model, dynamic simulations are used to consider stability and resilience, which represent restrictions for the market in the first layer. After market clearing, schedules and uncertainties are evaluated according to resilience and sustainability criteria using simulative studies. Within the market constraints, further optimization can thus be performed to further improve the target values for plants. The overall goal is a toolchain developed jointly with all project partners, which is freely available afterwards.
In the EffiziEntEE project, the TUHH primarily deals with the second layer for modeling and simulation of sector-coupled, or multi-modal energy networks. The central tool is the open description and modeling language Modelica with the TransiEnt Library developed in it.
In this context, many research fields arise. In case of interest - for example for project work and theses - the mentioned staff members are available.
