Within the energy and economic research area long term tendencies of energy system developments are analysed by the help of energy system models for operation and extension planning. These build a foundation for entrepreneurial or political decisions of a strategic kind and nowadays become of increasing importance (turnaround in energy policy). However, at the modelling stage, the electrical power network is often only modelled in a rudimentary way. This is due to the fact, that the technical and physical correct model of the networks within optimized energy system models is highly complex with respect to the mathematical challenges regarding the nonlinear and non-convex structures. Therefore, in practice often a linearized approach is considered for the computation of the power flow within energy system models. However, important electrotechnical features are missed. The scope of the proposed research project includes the development of appropriate mathematical models as well as efficient numerical solvers, which are able to take into account the physical correct power flows integrated in energy system models. The goal is to decouple the problem at modelling stage, such that nonlinear power flows can be computed separately from the linear economic optimization in an iterative way.

在能源和经济研究领域，借助用于运行和扩展规划的能源系统模型来分析能源系统发展的长期趋势。这些为战略性的创业或政治决策奠定了基础，并且如今变得越来越重要（能源政策的转变）。然而，在建模阶段，电力网络通常仅以基本方式进行建模。这是因为，优化能源系统模型中网络的技术和物理正确模型对于非线性和非凸结构的数学挑战非常复杂。因此，在实践中，通常考虑使用线性化方法来计算能源系统模型内的功率流。然而，重要的电技术特征被遗漏了。拟议研究项目的范围包括开发适当的数学模型以及高效的数值求解器，这些模型能够考虑能源系统模型中集成的物理正确功率流。目标是在建模阶段解耦问题，以便可以以迭代方式与线性经济优化分开计算非线性功率流。
