Analysis of the electrical characteristics of medium-voltage grids regarding the optimization during high energy input from wind energy systems

(Analyse der elektrischen Eigenschaften von Mittelspannungsnetzen in Hinsicht auf eine Optimierung bei hoher Einspeisung aus Windenergieanlagen)

The aim of the project is to accurately analyze the behavior of medium-voltage grid. A measurement system by using parallel inverters will be designed and implemented to analyze grid impedance and also harmonics. The grid impedance at certain frequency is based on the injection of non-characteristic harmonic current and the extraction of resultant voltage harmonic. Additionally, the system can function as reactive power supply and active power filter. [read more].

The research findings enable improved guidelines and grid codes for the medium-voltage grid, which leads to a better integration of renewable energy systems. The project benefits from the cooperation with FH Kiel and six partners from industry and will be run for 3 years involving 3 PhDs and Post-Docs at Kiel University.

Research

  • Our research is focused on the design of high efficient and reliable PWM-based power converter architectures (single-cell, multi-cell, multilevel), their modelling and control to exploit commercial as well as new power semiconductor devices with minimum over design.
    We develop controllers for electric drives and we are particularly skilled in the integration of renewable energy systems into the electric grid.
