In the course of the so-called "Energiewende" in Germany the power supply becomes more local and more fluctuating, especially due to the transition towards renewable energies. Those changes have to be considered in net planning not only in the high voltage grid, but also in middle and low voltage grids. Newly planned grids have to be particularly stable in voltage. To guarantee stability at all times, a robustness to fluctuations in load and supply is necessary. This robustness is analyzed by conducting a parametric sensitivity analysis, when the power in a network is considered as an optimization parameter in the classical power-flow problem. Simulative results are obtained on a real-world 20 kV voltage network.
