Advanced Control Methods for Power Systems and HiL


The growth of renewable energy generation results in a massive transformation of the power system due to the large-scale integration of power electronic converters. This transformation calls for advanced control and protection methods as well as rigorous testing of new concepts using, for example, a hardware in the loop (HiL) approach. Our team addresses performs research in the following topics:

  • Modelling and control of power electronic converters in power systems
    • Distributed control and optimization
    • Model predictive control
    • HVDC and MVDC control & protection
  • Microgrids
    • Grid-forming
    • Islanded microgrids
  • Stability analysis
    • Wideband impedance measurement
    • Harmonic stability assessment
  • Hardware in the Loop (HiL)
    • Power-HiL for wind turbine testing
    • Distributed real-time power system simulations

ENSURE Phase 3

ENSURE (Neue EnergieNetzStruktURen für die Energiewende) is one of the four Kopernikus projects launched by the German Federal Ministry of Education and Research (BMBF) in 2016. As the most important research initiative for implementing the energy transition, it brings together 29 partners from industry, research and education. Phase 3 started in August 2023 and will run for three years. More



VirTuOS is a research project funded by the BMWK that aims to establish a distributed test infrastructure for wind turbines (WT) at component level. As part of the project, a component test bench for testing the main converter of a WT is being developed and commissioned. The underlying idea is to replace parts of the overall system of the real WT by real-time simulations of the missing components. More


Junior Research Group: “Design and Verification of Control & Protection in DC Systems”

This junior research group explores integrated design and verification methods for DC systems. The developed methods address the complexity of a quickly changing electricity grid and its involved software. This research happens on the border between power systems and power electronics and aims for a better understanding between these two domains. In particular, the aim is to reduce planning and commissioning time and - through optimization - reduce cost. A particular emphasis is put on digital solutions based on artificial intelligence, graph theory, and open-source software. More



The future electricity network envisioned by READY4DC will be characterized by a growing role of multi-terminal multi-vendor (MTMV) HVDC solutions within the current AC transmission networks both onshore and offshore. READY4DC is contributing to this synergistic process by enabling commonly agreed definitions of interoperable modelling tools, model sharing platforms, clear processes for ensuring interoperability, and an appropriate legal and political framework. The project partners are: ENTSO-E, University of Groningen , SuperGrid Institute, T&D Europe, Tennet and WindEurope. More


REDeFINE - REflex-based Distributed Frequency control for power Networks

REDeFINE is a DFG-funded research project with the goal of developing distributed frequency control for future power grids. Within the project, especially approaches of model predictive control and the interaction with grid-forming converters are investigated. Communication systems play an important role and the influence of communication delays as well as data loss will be analyzed. The project is conducted in cooperation with the communication chair COMSYS of RWTH and with the partner project aDaptioN in the USA. More


FEN ESCape: Einheitliche Schutzarchitektur für DC-Netze auf System- und Komponentenebene

A mature protection architecture for smart power grids of the future, in particular direct current (DC) grids, is the key to the broad acceptance and market penetration of these grids. Requirements based on application scenarios will be evaluated for the necessary protection architecture, and the individual protection components. In addition, the higher-level coordination of all components involved in protection will be adapted to these requirements. Furthermore, the individual faults must be automatically detected, localized and cleared. In turn, reliable protection components are required to clear the faults, depending on the requirements imposed by the grid used. More


FEN DC-Sek: Control and Automation of Hybrid AC/DC Distribution Grids, with consideration of Cyber-physical Security Aspects

High integration of power electronics-interfaced distributed energy resources (DER) is a key factor of the energy transition in the modern power systems. This can be facilitated through DC systems, integrated in the existing AC distribution grids, forming hybrid AC/DC networks. More
