Modern power systems need to be controlled and optimized as dynamical systems in real time, rather than as stationary systems as is the case today. To properly deal with strong decentralization, new long distance DC transmission lines, and the increased randomness in power generation, we plan to set up complete model hierarchies of different modeling granularity that can be used for different simulation, control, and optimization tasks. As basis we will use energy-based models (port-Hamiltonian systems) of partial differential-algebraic equations that also allow the appropriate treatment of stochasticity and time-delay.
