The current focus of the energy transition is mainly on power generation, transportation networks and electric mobility. However, in terms of creating a CO2-neutral energy supply, perspectives must be broadened because the energy cycle includes generation, conversion, transport, storage, and consumption in electricity, gas, and thermal grids.
Regardless of the energy medium, information technology and mathematics encounter a number of basic recurring problems in the modeling, simulation, and control of hierarchical energy grids with stochastic production and usage.
In Project MathEnergy, sponsored by the Federal Economics Ministry, the solution to this problem is to be found in the development of mathematical methods, collected in a software library, and demonstrated in the fields of gas and electricity and even in a coupling of the two.
The project is divided in the following segments:
- overall grid modeling
- model reduction
- scenario analysis
- state estimation
- control, overall integration and demonstrators
Our department, in particular, is working on a grid-independent, model-based monitoring and control concept for the planning and operation of the electricity transport and distribution grid.
