MathEnergy - Mathematical Key-Technologies for Energy Grids in Transition, Subproject: analysis of scenarios of coupled gas and electricity nets

For a sustainable and CO2-neutral energy supply the entire energy cycle in electricity, gas and heat nets has to be taken in to account. For a reliable supply and efficiency of net load and upgrading, respectively, supply and demand should be balanced and flexibilities among energy sources should be used by storage. This requires vertical communication among the net levels as well as horizontal communication among the energy sources. In spite of rapid progress in hard- and software, energy economics is only insufficiently prepared for the overriding problems of monitoring and control as well as the exchange of data and models. The MathEnergy network project is designed to overcome this deficiency. Altogether, the network aims at developing a software library for hierarchical, parametric, nonlinear, switch und dynamical net models with stochastically varying quantities as well as work flows and standardization for an integrated simulation and analysis of multi network scenarios of energy supply with electricity and gas. Within the subproject at the institute of mathematics at the Humboldt-University Berlin various new mathematical models and methods for the analysis of scenarios of separate and coupled gas and electricity nets are developed, implemented and tested for an efficient control of such nets. Here, focus is on nettopological decompositions, model reductions by means of parameter differences as well as the application of splitting methods.
