Motivated by the potential transient oscillation risks in inverter based resource (IBR) dominated power systems, the paper is to identify the unwanted control interactions between traditional synchronous machines (SMs) and IBRs during system-split situations. Modal impedance analysis method is applied to reveal oscillation risk and the underlying m...
Local reactive power control in distribution grids with a high penetration of distributed energy resources (DERs) will be essential in future power system operation. Appropriate control characteristic curves for DERs support stable and efficient distribution grid operation. However, the current practice is to configure local controllers collectivel...

We introduce recent developments in the open source Python libraries pandapower and pandapipes. The purpose of pandapower is to provide an easy to use tool for power system analysis and enable a high degree of workflow automation. We describe the recent developments that extend the functionality of pandapower, such as new elements and controllers,...
The increasing penetration from intermittent renewable distributed energy resources in distribution grid brings along challenges in grid operation and planning. To evaluate the impact on the grid voltage profile, grid losses, and discrete actions from assets (e.g. transformer tap changes), quasi-static simulation is an appropriate method. Quasi-sta...
Power systems are rapidly and significantly changing due to the increasing penetration of distributed energy resources (DERs) and the rapid growth of widespread grid interconnections. An increasing number of grid operators is thus interested in the reduced equivalent representation of a large, interconnected power system to reduce the amount of req...
In the past decades, power systems worldwide have increased in size and complexity due to the increasing penetration of distributed energy resources and the rapid growth of widespread grid interconnections. The frequent grid state changes and the use of local controllers make the determination of appropriate grid equivalents challenging. Convention...
In this chapter, we introduce various applications for artificial neural networks in the context of power systems. Due to a fast pace of development in recent years, multiple libraries for setting up and training artificial neural networks are available as open-source software. In the field of power system analysis, the open-source software pandapo...
Im Rahmen des Projekts RPC2 (Reactive Power Control 2) wird eine netzebenen- und netzbetreiberübergreifende Betriebsführung vom Fachgebiet Energiemanagement und Betrieb elektrischer Netze (e2n) der Universität Kassel und dem Fraunhofer IEE mit den Verteilnetzbetreibern (VNBs) LEW Verteilnetz GmbH (LVN) und AllgäuNetz (AN) entwickelt und angewendet....
