Power Grid Research For Practical Application

Together with 20 partners, Helmuth Schmidt University researches novel grid impedance measurements on high-voltage levels

The energy and climate goals defined in the energy concept by the German Federal Government can only be achieved through a strong increase of Renewable Energy Sources (RES) in the power production. For this task, a simultaneous grid expansion is needed to integrate large wind farms in Northern Germany into the existing grid structure. Timing and planning of this expansion is crucial for the success of the energy concept.

HSU Supports Energy Transition With Research

Hamburg-based Helmuth Schmidt University (HSU) is actively supporting Germany’s energy transition with numerous research projects, including the modeling of grid connected wind energy converters, the BMWi projects for the development of a device for measurements of time- and frequency-dependent grid impedances at medium voltage level and high-voltage level, and the EU project “Facilitating energy storage to allow high penetration of intermittent renewable energy”. Further research topics include pumped-water plants in former open coal mining areas for usage as longtime storage, and grid storage concepts by integration of electromobility.

New Measuring Device For High AC Voltages

Recent results of research include a new device. Developed by HSU, it allows to measure AC voltages up to 20,000 volts. The Hamburg scientists worked five years on its development. The special feature of the power-measuring device: it rates the “inner life” of energy supply networks with high voltages. In addition, it measures the frequency response of the networks, which previously has was not possible. The Federal Ministry of Economy and Energy (BMWi) supported the three-year research project “Network harmony” in the context of the research initiative “Future electricity networks” with a total of 5.2 million euro. Helmut Schmidt University Hamburg (HSU) received 867,000 euro of funds.
