ANM4L

The ERA-NET project ANM4L started in December 2019. The project aims at demonstrating how innovative active network management (ANM) solutions can increase the integration of renewable energy sources (RES) in electricity distribution networks. ANM solutions will consider both management of active and reactive power to avoid overload situations, maintain voltages within limits, minimize the need of RES curtailment, and enable further RES uptake even when the theoretical design limit of the network has been reached.

InFIS

The realization of new laboratory facilities for design and assessment of next generation urban energy systems is on the way at RWTH Aachen University within the Urban Energy Lab 4.0 project. The InFIS, a subproject of Urban Enegy Lab 4.0 will enable the interconnection of laboratories into a unique research infrastructure for the holistic simulation and flexible testing of novel devices and solutions. The virtually interconnected research infrastructure comprises a real-time simulation environment, test bench for PV-Battery systems, wind turbine nacelle test bench (CWD), test bench for heat pumps (HELENA), user comfort and user behavior testing environment (Raumklimalabor) and test bed for building components (FlexFass).

Certification Investigation of Wind Energy Converters (WEC)

The experience from decades of WEC in operation shows that there are still unsolved reliability issues regarding electrical and mechanical components. Moreover, as the share of wind energy increases constantly, it is critical that the certification to be fulfilled before connection to the grid is clear and feasible. Designing the hardware in the loop test benches of the CWD at RWTH Aachen so that they realize repeatable conditions and are fit for certification is one of the main foci of ACS. More

 

Non-linear Power System Modeling, Simulation and Analysis in the Frequency Domain using Behavioral Modeling Approaches

In modern power systems, more and more non-linear components like power electronics devices are present. The non-linearities lead to voltage and current harmonics. Present frequency domain methods assume linear models, which are no longer valid in the presence of more and more power electronics devices. This project aims at developing a new power system theory based in the frequency domain. The used behavioral models of non-linear components are based on measurements. More
